ELECTRIC POWER GENERATION PLANT

摘要

An electric power generation plant (10) provided with: a gas turbine (11) using fuel gas as the fuel; a fuel gas cooler (13) for cooling, by means of cooling water, fuel gas which is pressurized by a fuel gas compressor (12) and recirculated; and a dust collection device (25) for separating and removing impurities from fuel gas led to the fuel gas compressor (12). The electric power generation plant is also provided with a heating means (51) for heating fuel gas, which is led to the dust collection device (25), using fuel gas utilized to cause an anti-thrust force to act on the rotor of the fuel gas compressor (12).
