Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明は燃料電池を組込んだ発電システムに関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application] The present invention relates to a power generation system incorporating a fuel cell.
現在、固体電解質燃料電池を用いた発電システムは主に
アメリカにおいて開発中であり、1990年代後半の実用化
が目標とされている。したがって、現在商用化されてい
るものはないが、そのシステム構成については種々検討
されている。そして、これらの発電システムでは従来の
発電システムでは得られない、約50％という高い熱効率
が達成できることが期待されている。Currently, a power generation system using a solid oxide fuel cell is under development mainly in the United States, and its practical application is targeted in the latter half of the 1990s. Therefore, although there is no commercialized one at present, various studies have been made on its system configuration. It is expected that these power generation systems can achieve high thermal efficiency of about 50%, which cannot be achieved by conventional power generation systems.
上述したような発電システムのうち石炭ガス化炉と固体
電解質燃料電池とを組み合わせたものにおいては、石炭
ガス化用のガス化剤として深冷分離法による酸素を、ま
た燃料電池での酸化剤として主に空気をそれぞれ用いる
ことが検討されている。Among the power generation systems as described above, in a combination of a coal gasification furnace and a solid oxide fuel cell, oxygen by a deep-separation method is used as a gasifying agent for coal gasification, and as an oxidant in a fuel cell. It is mainly studied to use air respectively.
しかし、石炭ガス化用の酸素を得るために深冷分離法を
用いた場合、起動に極めて長時間を要し、しかも負荷変
動に対しては対応が遅いため、迅速な起動・負荷変動を
要する発電用としては不向きである。また、深冷分離法
で製造される酸素は高純度（99％）であるが、石炭ガス
化炉のガス化剤としては必ずしもこのような高純度の酸
素を用いる必要はない。However, when the cryogenic separation method is used to obtain oxygen for coal gasification, it takes a very long time to start up, and it is slow to respond to load fluctuations, so quick startup and load fluctuations are required. Not suitable for power generation. Further, although oxygen produced by the cryogenic separation method has high purity (99%), it is not always necessary to use such high purity oxygen as a gasifying agent for a coal gasification furnace.
一方、燃料電池での酸化剤として空気を用いた場合に
は、効率が十分に高いとはいえず、効率向上の余地が残
されている。On the other hand, when air is used as the oxidant in the fuel cell, the efficiency cannot be said to be sufficiently high, and there is room for improvement in efficiency.

It is intended to provide a power generation system.

特徴とするものである。The fuel cell power generation system of the present invention has a pressure swing type oxygen-enriched air manufacturing apparatus that is supplied with air to generate oxygen-enriched air and nitrogen that is a by-product, a lock hopper, and a coal gasification furnace main body, and The lock hopper supplies coal to the coal gasification furnace main body using nitrogen supplied from the oxygen-enriched air manufacturing apparatus as a medium, and the coal gasification furnace main body supplies oxygen-enriched oxygen supplied from the oxygen-enriched air manufacturing apparatus. A coal gasification furnace that reacts air and coal supplied from the lock hopper to generate a fuel gas, oxygen-enriched air supplied from the oxygen-enriched air manufacturing apparatus, and the coal gasification furnace are supplied. And a fuel cell for generating electricity by reacting with a fuel gas, wherein the oxygen concentration of the oxygen-enriched air produced by the oxygen-enriched air production apparatus is 50 to 95% by volume. And It

効に用いられる。The pressure swing type oxygen-enriched production apparatus used in the method of the present invention is easy to start and stop, and has good followability to load fluctuations. Moreover, the operating temperature is close to room temperature,
Unmanned exercise is also possible. Further, in the coal gasifier, if the oxygen concentration of the oxygen-enriched air is high to some extent, the efficiency does not decrease so much as compared with the case of using high-purity oxygen. For fuel cells, if the oxygen concentration of the oxygen-enriched air is high to some extent, the efficiency will be much higher than with air. Further, the required power of the oxygen enriched production apparatus may be small when high-purity oxygen is not required. Therefore, high thermal efficiency can be obtained by using oxygen-enriched air as a gasification medium of a coal gasification furnace and an oxidizer of a fuel cell. Further, nitrogen, which is a by-product of the oxygen-enriched air manufacturing apparatus, is effectively used as a lock hopper medium for coal gasification furnaces.
なお、本発明において酸素富化空気の酸素濃度を50〜95
体積％としたのは以下のような理由による。すなわち、
50体積％未満では酸素富化空気製造装置の所要動力は小
さくてすむが、石炭ガス化炉及び燃料電池の効率が低い
ので全体的には高い熱効率が得られない。一方、95体積
％を超えると、石炭ガス化炉及び燃料電池の効率は高く
なるが、酸素富化空気製造装置の所要動力が非常に大き
くなってしまうので全体的には高い熱効率が得られな
い。In the present invention, the oxygen concentration of the oxygen-enriched air is 50 to 95.
The reason why volume% is set is as follows. That is,
If it is less than 50% by volume, the power required for the oxygen-enriched air manufacturing apparatus can be small, but the thermal efficiency of the coal gasification furnace and the fuel cell is low, so that high thermal efficiency cannot be obtained overall. On the other hand, if it exceeds 95% by volume, the efficiency of the coal gasification furnace and the fuel cell will be high, but the required power of the oxygen-enriched air production equipment will be very large, so high overall thermal efficiency cannot be obtained. .

装置１の副産物を利用すれば効率的である。H 2 , CO + O 2 → H 2 O, CO 2 ... The output (DC) of the solid electrolyte fuel cell 4 is converted into AC by the inverter 5. Further, the exhaust gas of the fuel cell 4 is exhausted after its heat quantity is recovered by the heat exchanger 6. The steam turbine 7 is operated by the amount of heat recovered by the heat exchanger 6. In addition, the oxygen-enriched air manufacturing apparatus 1
The by-product N 2 (partly containing O 2 ) can be used as an inert gas such as a lock hopper medium of the coal gasification furnace 2. That is, a lock hopper is provided at the raw material supply port of the coal gasification furnace 2 so as to supply coal to the gasification furnace body pressurized from the outside at atmospheric pressure. This lock hopper is composed of at least three stages of a normal pressure hopper, an intermediate hopper and a pressure hopper, and sequentially feeds coal by a valve operation using an inert gas as a medium. Coal is first fed from the atmospheric hopper at atmospheric pressure to the intermediate hopper by valve operation. Next, after closing the valve between the normal pressure hopper and the intermediate hopper to pressurize the intermediate hopper to the same pressure as the gasifier, coal is fed from the intermediate hopper to the pressure hopper by valve operation. Further, the coal is fed from the pressure hopper to the gasification furnace main body by the same valve operation. Since coal is kept under pressure in the intermediate hopper and the pressure hopper for a considerable time, using air as a medium may cause spontaneous combustion or explosion. Therefore, an inert gas is used as the lock hopper medium.
As described above, it is efficient to use the by-product of the oxygen-enriched air manufacturing apparatus 1 for this lock hopper medium.
上記発電システムの熱効率は酸素富化空気製造装置１で
製造される酸素富化空気の酸素濃度に応じて第２図に示
すように変化する。The thermal efficiency of the power generation system changes as shown in FIG. 2 according to the oxygen concentration of the oxygen-enriched air produced by the oxygen-enriched air producing apparatus 1.
（Ｉ）まず、石炭ガス化炉２とガス精製装置３の効率
は、酸素富化空気の酸素濃度が高くなればなるほど上昇
するが、酸素濃度がかなり高くなると上昇率は緩やかに
なる（第２図中Ｉで表示）。(I) First, the efficiencies of the coal gasifier 2 and the gas purifier 3 increase as the oxygen concentration of the oxygen-enriched air increases, but the rate of increase decreases as the oxygen concentration increases considerably (second (Indicated by I in the figure).
（II）燃料電池４の出力電圧は下記式で表わされる。(II) The output voltage of the fuel cell 4 is represented by the following formula.
Ｅ＝RTlnP′o2/P″o2 …… ここで、E:基準電圧、R:ガス定数、T:温度、Ｐ′o2：酸
化剤側のO2分圧、Ｐ″o2：還元剤側のO2分圧である。そ
して、Ｐ′o2は常圧の空気の場合0.21atmであるが、酸
素富化空気のO2分圧はこれより高くなり、電圧Ｅも高く
なる。したがって、燃料電池４の効率は酸素富化空気の
酸素濃度が高くなると上昇するが、酸素濃度が90体積％
以上になるとほとんど上昇しない（第２図中IIで表
示）。E = RTlnP′o 2 / P ″ o 2 …… where E: reference voltage, R: gas constant, T: temperature, P′o 2 : partial pressure of O 2 on the oxidant side, P ″ o 2 : reduction O 2 partial pressure on the agent side. Then, P'o 2 is 0.21 atm in the case of normal pressure air, but the O 2 partial pressure of oxygen-enriched air becomes higher and the voltage E also becomes higher. Therefore, the efficiency of the fuel cell 4 increases as the oxygen concentration of oxygen-enriched air increases, but the oxygen concentration is 90% by volume.
When it becomes above, it hardly rises (indicated by II in Fig. 2).
（III）一方、圧力スウィング方式の酸素富化空気製造
装置の効率ロス（主にコンプレッサ動力）は、酸素濃度
が90体積％以上になると極めて高くなってしまう（第２
図中IIIで表示。破線はロスであることを示す）。(III) On the other hand, the efficiency loss (mainly compressor power) of the pressure swing type oxygen-enriched air manufacturing apparatus becomes extremely high when the oxygen concentration becomes 90% by volume or more (second).
Shown as III in the figure. The broken line indicates loss).

ックホッパ媒体として有効に用いられる。The overall thermal efficiency is expressed as the sum of the above three factors (indicated by A in FIG. 2). As can be seen from the curve A in FIG. 2, there is an optimum value for the oxygen concentration of the oxygen-enriched air, considering the overall thermal efficiency. As a result of detailed investigation of the thermal efficiency and cost of the method of the present invention, the present inventors have found that the optimum oxygen concentration of the oxygen-enriched air produced by the oxygen-enriched air production apparatus is 50 to 95% by volume. I found it. Further, nitrogen, which is a by-product of the oxygen-enriched air manufacturing apparatus, is effectively used as a lock hopper medium for coal gasification furnaces.
