Abstract
PURPOSE: To reduce plant investment greatly without degrading the effectiveness of the conventional plant and its function by providing another drain tank to convert heat recovery course and by minimizing the drain tank in capacity.
CONSTITUTION: Drain from the low-pressure secondary feed-water heater 7 is led to a drain tank 27 in connection to the low-pressure primary feed-water heater 6 by a flush pipe, and its steam generated by self-evaporation is recovered into the low- pressure primary feed-water heater 6. Drain in the low-pressure primary feed-water heater 6 is recovered into the drain tank 27 through a drain pipe 22 and fed into the upperstream condensation pipe 5 of a condensing dechlorination unit 4 by a pump 8. A volume of drain is controled by a control valve 33 which opens or closes depending on a signal of a water-level controller 31 of the drain tank 27
