Abstract

PURPOSE:To enable to operate a power plant at a high efficiency and with a high reliability if fuel containing a high percentage of sulfur is used, by utilizing a portion of low-pressure steam supplied to steam turbine for heating an deaerator. CONSTITUTION:A portion of high-pressure, high-temperature water at the outlet of low-pressure economizer 21 is delivered through deaerator recirculating pipe 54 into fluish tank 36, where it is separated into low-pressure steam and drain. The low-pressure steam in the tank 36 is delivered to deaerator 35 through deaerator heating steam pipe 56. Here, pressure in the deaerator 35 is controlled by controlling an adjustment valve by pressure regulator 38 and thereby controlling the amount of steam supplied to deaerator 35 through pipe 56. Further, connecting pipe 62 having an adjustment valve 61 is provided between low pressure steam pipe 53 and deaerator 35. This adjustment valve 61 is controlled by a signal from pressure regulator 38. On the other hand, water supplied from deaerator 35 is delivered to low-pressure economizer 21 through main water supply pipe 55 by means of low- pressure boiler feed pump 37.
