Abstract

PURPOSE: To provide in an economizer part, relating to a boiler mentioned in the title in combined cycle power generation equipment, an economizer bypass pipe having a flow control valve so as to stabilize the operation and improve the thermal efficiency. CONSTITUTION: The exhaust gas from a gas turbine 22 is drawn from a duct 23 into an exhaust gas recovery boiler 10, made to flow through a superheater 6, evaporator 5, and economizer part 1 and is discharged to the atmosphere with heat exchange in the meanwhile. On the other hand, the economizer part 1 is supplied with water by a feedwater pipe 9, and after heat exchange, drawn into a drum 7. The saturated water in the drum 7 is sent by a circulating pump 25 to the evaporator 5 and the steam evolved is sent to the superheater 6. At this time if the warm water temperature at the outlet in the economizer part 1 rises, a three-way valve 15a is shifted so that the water supplied is directly led by a bypass pipe 15 to a header 17 so as to lower the warm water temperature at the outlet in the economizer 1. This method enables preventing abnormal phenomenon, or the like inside the economizer part.
