した蒸気をライン５から生成蒸気として取出す。 Conventionally, this type of steam generator employs a forced vaporization type or a bubbling type. Figure 1 shows a forced vaporization steam generator. In this method, while heating the evaporator 1 to a predetermined temperature by the heating means 2, the liquid to be evaporated is added to the evaporator 1 from a line 3, and gas is sent into the evaporator 1 from a line 4. The vapor generated by vaporizing the liquid on the inner surface of the tube is taken out from line 5 as generated vapor.

置では所望の蒸気濃度を長期間にわたり安定して
得ることはできない。 In a forced vaporizer, the concentration of generated vapor is controlled mainly by changing the discharge flow rate of the liquid feed pump. Fluctuations in the discharge flow rate of the liquid pump directly affect fluctuations in the concentration of generated steam, so
The vapor concentration fluctuates due to the pulsating flow of the pump, etc. In addition, a liquid pump for generating low-concentration steam of 10 ppm or less is quite small, and it is difficult for this type of pump to supply liquid stably. Furthermore, the concentration of generated vapor can only be changed within this pump flow rate adjustment range. In addition, the liquid dripped onto the inner wall of the evaporating pot causes the temperature distribution on the inner wall of the evaporating pot to become non-uniform, thereby causing fluctuations in the concentration of generated vapor. As described above, the forced vaporization type steam generator cannot stably obtain a desired steam concentration over a long period of time.

変動する。 In a bubbling steam generator, fluctuations in the concentration of generated steam depend on the bubbling state. The bubbling state is influenced by various factors such as gas flow rate, blowing pressure, liquid depth, and liquid temperature. Since fluctuations in these factors cannot be completely eliminated, the concentration of generated steam in a bubbling steam generator varies considerably.

The air used in the present invention may be collected from the atmosphere. This air may be directly supplied to the steam generator, but if desired, the air may be purified through a moisture adsorption tower 12 filled with silica gel or the like, an activated carbon adsorption tower 13, and a dust removal filter 14. The air thus purified is pumped by the pump 15. The pressure-fed air passes through line 16, and its flow rate is adjusted by mass flow meter 17. Since the mass flow meter 17 is normally open, the mass flow meter 17 is activated due to excessive flow when the pump 15 is activated. Therefore, at startup, an excessive flow rate of air is blown onto the liquid surface 21, resulting in a concentration higher than the set value. In this case, the generated steam is guided to a line 19 by a three-way valve 18 and exhausted, and after the steam concentration becomes constant, the steam is transferred to a line 10 and supplied to the main duct 11. This transient time is less than 1 minute. Although it is possible to practice the invention without the mass flow meter 17, if the set steam concentration is low, it is preferable to use the mass flow meter 17 to make the steam concentration more stable.
