Abstract

PURPOSE: To prevent the flooding phenomenon in a tray chamber by separately forming the tray chamber and a spray chamber and introducing heater steam.

CONSTITUTION: Heated steam is introduced separately into a tray chamber 2 and a spray chamber 3. Namely, heated steam inlet pipes 4a and 4b equipped with a temperature controlling value 6 respectively are fitted separately on the tray chamber 2 and the spray chamber 3, and a thermometer 7a is mounted at the lower part of the spray chamber 3. The temperature of supplied water in the spray chamber 3 is detected by the thermometer 7a, and is transmitted to the temperature controlling valve 6, and the flow amount of steam which flows into the tray chamber 2 and the spray chamber 3 is controlled by opening and closing the temperature controlling valve 6. Thus, the amount of steam which flows into the tray chamber 2 is restricted, and the volume of steam in the tray chamber 2 is kept constant, so flooding phenomenon can be prevented. In the spary chamber 3, the water supplied is contacted with heated steam in high temperature, and heat exchange can be performed in a high efficiency.
