Special Publication No. 2014-513260

However, unlike hydrate-based and organic-based latent heat storage materials, metallic latent heat storage materials are corrosive and require a suitable protective layer to prevent erosion. Since this protective layer is consumed with use, periodic maintenance, such as recoating the protective layer, is necessary. In the case of integrated systems where metallic latent heat storage materials are stored in large tanks constructed on-site, it becomes difficult to guarantee the quality of the protective layer during on-site assembly and maintenance within the plant. Therefore, while it is preferable to assemble the aforementioned storage vessels in the factory from the standpoint of quality assurance and maintenance, this presents challenges in transporting the vessels and their placement on-site, hindering the practical application of regenerative heat exchangers using metallic latent heat storage materials.

This disclosure aims to solve the aforementioned problems and provide a regenerative heat exchanger utilizing a metallic latent heat storage material with an appropriately sized modular structure that enables quality assurance, transportation, and maintenance within the plant for the erosion prevention protective layer.

To achieve the above objective, the regenerative heat exchanger of this disclosure comprises at least one heat transfer tube for heat dissipation, a heat storage section disposed around the heat transfer tube, capable of exchanging heat with the heat transfer tube, and filled with a metallic latent heat storage material, a protective layer disposed at the interface between the heat storage section and other components, a holding container disposed around the heat storage section to hold the heat storage section, and a heating section capable of exchanging heat with the heat storage section and for heating the heat storage section.

Furthermore, the regenerative heat exchange system of this disclosure comprises a plurality of regenerative heat exchangers as described above, and a holding mechanism for holding the regenerative heat exchangers in parallel. The regenerative heat exchangers are provided with support beams that protrude horizontally from the holding container, and whose upper, lower, or both vertical surfaces are in contact with the holding mechanism.

Furthermore, the power generation system of this disclosure comprises the regenerative heat exchange system described above, a turbine supplied with high-temperature steam from the heat transfer tubes of the regenerative heat exchanger, a generator connected to the turbine, and a heat source that supplies heat to the heating section.

Furthermore, the operating method for the thermal energy storage heat exchange system described herein is the operating method for the thermal energy storage heat exchange system described above, wherein the system includes multiple storage compartments, identifies the compartment to be maintained from among the multiple storage compartments, and performs maintenance on the target compartment while operating the other compartments.

According to this disclosure, compared to an integrated design, quality assurance of the erosion-preventive protective layer and maintenance can be easily performed within the plant. Furthermore, during maintenance, only the affected module needs to be replaced with a pre-maintained module, thus reducing the decrease in plant operating rate associated with maintenance.

Preferred embodiments of this disclosure will be described in detail below with reference to the drawings.

Furthermore, the components in the embodiments include those readily conceivable by those skilled in the art, those that are substantially identical, and those within the so-called equivalent range.

<Power generation system>
Figure 1 is a schematic diagram showing a power generation system equipped with the regenerative heat exchange system of this embodiment. As shown in Figure 1, the power generation system 10 of this embodiment comprises a regenerative heat exchanger 13, a turbine 14, a generator 15, and a heating module 24. The heating module 24 of this embodiment is a power source that supplies power to the electric heater of the regenerative heat exchanger 13.

The regenerative heat exchanger 13 stores heat using energy supplied from the heating module 24. The regenerative heat exchanger 13 heats water/steam with the stored heat and supplies it to the turbine 14 via the heat dissipation circuit 20. The regenerative heat exchanger 13 will be described later.

The turbine 14 is supplied with heated steam from the heat dissipation circuit 20, and rotates due to the force of the steam passing through it. For example, the turbine 14 has rotor blades located in the rotating section and stationary blades located in the stationary section, arranged alternately in the direction of the rotation axis. Steam passes through the space between the rotor blades and stationary blades, applying a rotational force to the rotor blades, thereby rotating the rotating section. The structure of the turbine 14 is not particularly limited. The generator 15 is connected to the rotation of the turbine 14 and rotates together with the turbine 14 to generate electricity.

The heat dissipation circuit 20 is a conduit connecting the regenerative heat exchanger 13, the turbine 14, and the heat transfer fluid processing unit 22, circulating water (steam) in the order of regenerative heat exchanger 13, turbine 14, and heat transfer fluid processing unit 22. In this embodiment, water (steam) is used as the heat dissipation medium in the heat dissipation circuit 20, but various fluids such as various gases and liquids can be used as well as water. However, it is preferable to use a medium that undergoes a phase change from liquid to gas in the regenerative heat exchanger 13. This makes it possible to increase the power generation efficiency of the turbine 14. The heat dissipation circuit 20 receives water from the heat transfer fluid processing unit 22 via path 32, and supplies the steam generated by heating the water in the regenerative heat exchanger 13 to the turbine 14. The steam heated in the regenerative heat exchanger 13 rotates the turbine 14. The heat dissipation circuit 20 supplies the steam that has passed through the turbine 14 via path 32 to the heat transfer fluid processing unit 22. As a result, the heat dissipation circuit 20 circulates water (water vapor).

The heat transfer fluid processing unit 22 is located in the heat dissipation circuit 20 and processes the heat transfer fluid that has passed through the turbine 14 into a state that can be supplied to the regenerative heat exchanger 13. In this embodiment, the heat transfer fluid processing unit 22 includes a condenser that returns the heat transfer fluid that has passed through the turbine 14 back into a liquid, and a pump that controls the circulation of the heat transfer fluid. The heat transfer fluid processing unit 22 may also include a feedwater heater that heats the water that has passed through the condenser. The heat transfer fluid processing unit 22 controls the circulation of water (steam).

The heating module 24 supplies power to the regenerative heat exchanger 13 and heats the regenerative heat exchanger 13. While the heating module 24 can use various power sources, it is preferable to supply surplus power generated by the grid to the regenerative heat exchanger 13.

The regenerative heat exchanger 13 will be described below with reference to Figures 2 and 3. Figure 2 is a perspective view showing the schematic configuration of the regenerative heat exchanger. Figure 3 is a horizontal cross-sectional view showing the schematic configuration of the regenerative heat exchanger. Although Figures 2 and 3 show a single module of the regenerative heat exchanger 13, the power generation system 10 may be equipped with multiple modules of the regenerative heat exchanger 13.

The regenerative heat exchanger 13 is a structure filled with a heat storage material that stores supplied heat, and in this embodiment, it is a cylindrical structure. However, the external shape is not limited to this. The regenerative heat exchanger 13 comprises a heat storage section 100, a holding container 102, heat transfer tubes 104, a heating heater 106, and protective layers 108, 110, and 112. In this embodiment, a heating heater 106 is used as the heating module 24, but this is not limited to this, and heating tubes may also be used. This heat exchanger shape allows for quality assurance of the corrosion-preventive protective layer and enables maintenance within the plant.

The heat storage unit 100 is a latent heat storage material (PCM: Phase Change Material), which is made of metal, becomes a liquid phase when heated, and becomes a solid phase when heat is released. In other words, it is a metallic latent heat storage material. For example, the heat storage unit 100 can be made of aluminum mixed with other metals, or an aluminum-based metal.

The holding container 102 is a container that holds the heat storage unit 100. The holding container 102 is made of a material with a melting point higher than the operating temperature of the heat storage unit 100. For example, the holding container 102 is made of stainless steel. It is preferable that the holding container 102 surrounds the heat storage unit 100 with an insulating material or the like. The holding container 102 is provided with a support beam 120 that protrudes horizontally near its upper vertical end. The lower vertical surface of the support beam 120 contacts the horizontal support 64 of the holding mechanism 60 that supports the heat storage heat exchanger 13. In this embodiment, the explanation describes the case where the holding container 102 is suspended from above, but the holding container 102 may be supported by its bottom surface or its sides. The support beam 120 becomes the contact surface with the holding mechanism 60 and acts as a positioning member. The support beam 120 also includes a connection point for the suspension rod 130 used when moving the unit with a work crane, as described later.

The heat transfer tube 104 is a pipe connected to the heat dissipation circuit 20 and is inserted into the heat storage unit 100. Both ends of the heat transfer tube 104 are connected to the heat dissipation circuit 20, and the heat transfer medium flowing through the heat dissipation circuit 20 passes through it. In this embodiment, one heat transfer tube 104 is inserted into the heat storage unit 100. Note that the number of heat transfer tubes 104 is not limited to one; multiple tubes may be installed.

The heating element 106 is connected to the heating module 24 and generates electricity using power supplied from the heating module 24. When a heat transfer tube is used instead of the heating element, the portion of the heating element 106 becomes the heat transfer tube, which is a pipe connected to the heating circuit 18 and inserted into the heat storage unit 100. Both ends of the heat transfer tube are connected to the heating circuit 18, and the heat transfer medium flowing through the heating circuit 18 passes through it. In this embodiment, multiple heating elements 106 are inserted into the heat storage unit 100.

The protective layers 108, 110, and 112 are positioned at the interface between the heat storage section 100 and other components. Protective layer 108 is positioned at the boundary between the heat storage section 100 and the holding container 102. Protective layer 110 is positioned at the boundary between the heat storage section 100 and the heat dissipation heat transfer tube 104. Protective layer 112 is positioned at the boundary between the heat storage section 100 and the heating heater 106. The entire outer surface of the heat storage section 100 is covered by the protective layers 108, 110, and 112. The protective layers 108, 110, and 112 are made of a material with high corrosion resistance to the metallic latent heat storage material of the heat storage section 100. The protective layers 108, 110, and 112 suppress the metallic latent heat storage material from corroding other components. The protective layer is not particularly limited as long as it is a material capable of preventing erosion of the metallic latent heat storage material, but zirconium oxide can be given as an example.

Furthermore, by using a metallic latent heat storage material in the heat storage section 100 of the regenerative heat exchanger 13, and by providing protective layers 108, 110, and 112 around the heat storage section 100, the usable temperature of the heat storage section 100 can be increased, for example, from 400°C to 650°C. This allows for the storage of more heat and suppresses corrosion of other components by the heat storage section 100. As a result, it can be used for a longer period and the frequency of maintenance can be reduced.

Furthermore, by using an electric heater as the heating element for the heat storage section 100 of the regenerative heat exchanger 13, solar cells can be used as the power source. Also, even when heating with electricity, if surplus electricity is generated, heat can be stored, and then released to generate electricity when electricity demand is high, thereby stabilizing the power grid.

In this embodiment, the heating module 24 heats the regenerative heat exchanger 13 by supplying power, but the heat source is not limited to this. The heating module 24 can utilize various heat sources for heating the heat transfer medium, such as a heating furnace that generates heat by burning fuel, a solar thermal energy concentrator that heats an object by concentrating sunlight and using the heat from that object to heat the heating medium, or a nuclear reactor.

Figure 4 is a schematic diagram showing a power generation system equipped with a regenerative heat exchanger of another embodiment. Figure 4 is an example of a system that heats the regenerative heat exchanger 13 using a heat transfer medium. The power generation system 10a shown in Figure 4 comprises a regenerative heat exchanger 13, a turbine 14, a generator 15, a heating module 16, a heating circuit 18, a heat dissipation circuit 20, and a heat transfer medium processing unit 22. The turbine 14, generator 15, heat dissipation circuit 20, and heat transfer medium processing unit 22 of the power generation system 10a are the same as those in the power generation system 10, so their description is omitted. In this embodiment, the regenerative heat exchanger 13 has heating tubes instead of a heating heater 106. The heating tubes are positioned in the same location as the heating heater 106.

The heating module 16 is a heat source that heats the regenerative heat exchanger 13. In this embodiment, the heating module 16 heats the heat transfer medium (heating medium) circulating in the heating circuit 18. The heating module 16 can utilize various heat sources for heating the heat transfer medium, such as a heating furnace that generates heat by burning fuel, a solar thermal energy concentrator that heats an object by concentrating sunlight and using the heat from that object to heat the heating medium, or a nuclear reactor.

The heating circuit 18 is a conduit connecting the regenerative heat exchanger 13 and the heating module 16, circulating a heat transfer medium (heating medium) between the regenerative heat exchange system 12 and the heating module 16. Various media that move through the conduit can be used as the heating medium, and can be either a gas or a liquid. The heating circuit 18 circulates the heat transfer medium by supplying the heat transfer medium heated in the heating module 16 to the heating tubes of the regenerative heat exchanger 13, and then sending the heat transfer medium, from which heat has been absorbed in the regenerative heat exchanger 13, back to the heating module 16.

The power generation system 10a generates heat in the heating module 16 and supplies it to the regenerative heat exchanger 13 by circulating the heating medium through the path 30 of the heating circuit 18. The regenerative heat exchanger 13 is heated by the passing heating medium in its heat storage section 100. The heat storage section 100 stores the supplied heat. When the temperature of the heat storage section 100 is heated above a predetermined level, it enters the liquid phase. The heating medium that has passed through the heat transfer tubes of the regenerative heat exchanger 13 returns to the heating module 16 via the heating circuit 18. In other words, it circulates through path 30. Furthermore, the power generation system 10a circulates water (water vapor) through the same path as the power generation system 10, namely through path 32 of the heat dissipation circuit 20.

Thus, heat can also be stored by providing heating heat transfer tubes in the regenerative heat exchanger 13 and circulating a high-temperature heat transfer medium through the heating heat transfer tubes. In this case as well, by providing a protective layer 110 at the boundary between the heating heat transfer tubes and the heat storage section 100, the same effect as when using a heating heater 106 in the regenerative heat exchanger 13 can be obtained.

Figure 5 is a schematic diagram showing a power generation system equipped with a regenerative heat exchanger of another embodiment. Figure 5 shows an example of a system that heats the regenerative heat exchanger 13 using a heat transfer medium. The power generation system 10b shown in Figure 5 comprises a regenerative heat exchanger 13, a turbine 14, a generator 15, a heating module 16, a heating circuit 18, a heat dissipation circuit 20, and a heat transfer medium processing unit 22. Except for the configuration of the heating circuit 18, the power generation system 10b is the same as the power generation system 10a.

The heating circuit 18 connects the heating module 16 to the regenerative heat exchanger 13 and supplies the heat transfer medium heated by the heating module 16 to the regenerative heat exchanger 13. The heating circuit 18 then discharges the heat transfer medium that has passed through the regenerative heat exchanger 13 to the outside.

As in power generation system 10b, the heat source for heating the regenerative heat exchanger 13 can be a heat transfer medium passing through the regenerative heat exchanger 13, and the heat transfer medium can not be circulated. Furthermore, in this embodiment, power generation system 10b can utilize exhaust gas from a combustion furnace or incinerator as the heat transfer medium.

In the above embodiment, a power generation system using a single regenerative heat exchanger 13 module was used, but a power generation system using multiple modules can also be used.

The following describes the case where the regenerative heat exchanger 13 is composed of multiple modules. First, using Figure 6, the schematic configuration of a regenerative heat exchange system 12 having multiple modules of regenerative heat exchanger 13 will be described. Figure 6 is a schematic diagram showing the schematic configuration of a regenerative heat exchange system. As shown in Figure 6, the power generation system 10c of this embodiment comprises a regenerative heat exchange system 12, a turbine 14, a generator 15, a heating module 16, a heating circuit 18, a heat dissipation circuit 20, and a heat transfer fluid processing unit 22. The power generation system 10c has the same configuration as the power generation system 10, except that the regenerative heat exchange system 12 has multiple modules of regenerative heat exchanger 13. The heating module 16, heating circuit 18, and heat dissipation circuit 20 have different piping configurations corresponding to the multiple modules of regenerative heat exchanger 13, but their functions are the same as those of the power generation system 10.

The following describes the regenerative heat exchange system 12. The schematic configuration of the regenerative heat exchange system 12 will be explained using Figure 7. Figure 7 is a schematic diagram showing the schematic configuration of the regenerative heat exchange system. The regenerative heat exchange system 12, which has multiple modules of regenerative heat exchangers, comprises multiple compartments 40, a work crane 42, and a maintenance unit 44, as shown in Figure 7. Note that the maintenance unit 44 of the regenerative heat exchange system 12 may not be adjacent, i.e., it may be located in a remote location. The multiple compartments 40 are arranged adjacent to each other within the same site. Each compartment 40 is equipped with numerous regenerative heat exchangers 13. The compartments 40 will be described later.

The work crane 42 is a work machine that can move between the multiple compartments 40 and the maintenance section 44 in the vertically upper area between the multiple compartments 40 and the maintenance section 44. The work crane 42 can suspend and move the regenerative heat exchanger 13, and is used for positioning the regenerative heat exchanger 50 in the compartments 40 and moving the regenerative heat exchanger 13.

The maintenance unit 44 performs inspections and repairs of the regenerative heat exchanger 13. The maintenance unit 44 also has a regenerative heat exchanger 13 for replacement. The maintenance unit 44 inspects and repairs the regenerative heat exchanger 13 transported by the work crane 42. The regenerative heat exchange system 12 uses the work crane 42 to supply the regenerative heat exchanger 50, which is located in the maintenance unit 44, and the maintained regenerative heat exchanger 13, to a loadable position in section 40.

Next, section 40 will be described using Figures 8 and 9. Figure 8 is a side view showing the schematic configuration of one section of the thermal energy storage heat exchange system. Figure 9 is a top view showing the schematic configuration of one section of the thermal energy storage heat exchange system.

As described above, compartment 40 is equipped with multiple regenerative heat exchangers 13. Compartment 40 includes multiple regenerative heat exchangers 13, a holding mechanism 60, insulation material 62, wiring 70, a heat dissipation medium supply unit 80, and a heat dissipation medium discharge unit 82.

The holding mechanism 60 holds multiple regenerative heat exchangers 13. The holding mechanism 60 is a structure combining columns and beams, such as steel frames, with a space for arranging the regenerative heat exchangers 13. The holding mechanism 60 has horizontal support members 64. The horizontal support members 64 have holes that are smaller in diameter than the support beams of the regenerative heat exchangers 13, allowing the main bodies of the multiple regenerative heat exchangers 13 to pass through. The horizontal support members 64 contact the support beams of the regenerative heat exchangers 13, thereby supporting the regenerative heat exchangers 13.

The insulation material 62 is placed on the outer wall surface of the holding mechanism 60 and covers the space where the multiple heat storage type heat exchangers 13 are arranged. The insulation material 62 suppresses heat exchange between the space where the multiple heat storage type heat exchangers 13 are arranged and the outer region, thereby suppressing the heat dissipation of heat held by the multiple heat storage type heat exchangers 13. Regarding the insulation material, methods other than the construction method shown in this embodiment, such as directly applying it to the heat storage type heat exchangers 13, can also be used.

The wiring 70 connects the heating module 24 to the multiple regenerative heat exchangers 13. The wiring 70 transmits the power supplied from the heating module 24 to the multiple regenerative heat exchangers 13.

The heat dissipation medium supply unit 80 connects the end of the heat dissipation circuit 20 to the multiple regenerative heat exchangers 13. The heat dissipation medium supply unit 80 acts as a header for the multiple regenerative heat exchangers 13, supplying the heating medium from the heat dissipation circuit 20 to the multiple regenerative heat exchangers 13. The heat dissipation medium discharge unit 82 connects the end of the heat dissipation circuit 20 to the multiple regenerative heat exchangers 13. The heat dissipation medium discharge unit 82 acts as a header for the multiple regenerative heat exchangers 13, discharging the heat dissipation medium that has passed through the multiple regenerative heat exchangers 13 back to the heat dissipation circuit 20.

Furthermore, the regenerative heat exchanger 13 can be easily transported by providing a support beam 120 and suspending it. In this embodiment, the explanation describes the case where the holding container 102 is suspended from above, but the holding container 102 may be supported on its bottom or its sides. The support beam 120 serves as the contact surface with the holding mechanism 60 and acts as a positioning member. The support beam 120 also includes a connection point for the suspension rod 130 used when moving the unit with a work crane. The regenerative heat exchanger 13 is moved by being suspended via the suspension rod 130.

The thermal storage heat exchange system 12 has a structure that provides multiple compartments 40, allowing heat storage and release in other compartments even when the thermal storage heat exchanger 13 in one compartment 40 is being maintained. This increases operating efficiency. Furthermore, as in this embodiment, by arranging the thermal storage heat exchangers 13 horizontally in parallel with their axial direction (longitudinal direction) being vertical, the thermal storage heat exchangers 13 can be easily removed and installed.

In this embodiment, in section 40, the regenerative heat exchangers 13 are arranged in a single vertical row and horizontally in a matrix within the holding mechanism 60. However, the arrangement method is not particularly limited. They may be arranged in a staggered horizontal configuration. The regenerative heat exchangers 13 may also be arranged in two vertical rows within the holding mechanism 60. Furthermore, the axial direction of the regenerative heat exchangers 13 is not limited to the vertical direction; they may also be arranged in an inclined direction relative to the vertical or horizontally.

Furthermore, the power generation system 10 may be installed alongside a power generation facility using a boiler. In this case, the turbine 14 can be the same turbine used in the power generation facility using a boiler. The power generation system 10 can use the waste heat from the boiler of the power generation facility, or the surplus electricity generated by the power generation facility using a boiler, as a heat source (heat source) for the regenerative heat exchanger. Also, if power generation is required but cannot be done with the regenerative heat exchanger, power can be generated using the boiler.

Furthermore, when the power generation system 10 uses a heat transfer medium for heating and heat dissipation of the regenerative heat exchanger, it may be structured so that the heating medium and heat dissipation medium flow through the same heat transfer tube. For example, a three-way valve may be provided connecting the piping of the regenerative heat exchange system 12 to the heating circuit 18 and the heat dissipation circuit 20, and the heat storage and heat dissipation of the regenerative heat exchange system 12 may be switched by switching the three-way valve.

Furthermore, although the thermal storage heat exchanger 13 of this embodiment was described as a case where stored heat is released to generate electricity, it may also be used as a heat source for purposes other than power generation. For example, the heat stored in the thermal storage heat exchanger 13 may be used for heating or as energy for a steam generation source.
