Abstract:
1. A power plant comprising: a gas turbine that uses a fuel gas as a fuel; a fuel gas cooler that cools the fuel gas, which has been compressed by rotation of a rotor in a fuel gas compressor and which is to be re-circulated, using cooling water; and a dust collection device that separates/removes impurities from the fuel gas that is to be guided to the fuel gas compressor; wherein the rotor of the gas compressor is pushed toward one side along an axial direction of the rotor by a thrust force caused by compressing the fuel gas, and a part of the rotor is configured to be pushed by the compressed fuel toward the other side along the axial direction of the rotor so as to generate on the rotor an anti-thrust force against the thrust force, and wherein the power plant further comprises heating means that heats the fuel gas that is to be guided to the dust collection device using the fuel gas that has been used to generate the anti-thrust force.
