THERMAL POWER GENERATION SYSTEM

摘要

Provided is a thermal power generation system that has low operating costs given that the degradation of a denitration catalyst used in a denitration device is suppressed. Provided is a thermal power generation system 1 that is provided with a boiler 10 that burns a fuel, an exhaust path L1 through which an exhaust gas generated by the burning of the fuel in the boiler 10 flows, a desulfurization device 70 that is disposed in the exhaust path L1 and removes sulfur oxides from the exhaust gas, and a denitration device 90 that is disposed in the exhaust path L1 and removes nitrogen oxides from the exhaust gas by means of a denitration catalyst, wherein the denitration device 90 is disposed downstream of the desulfurization device 70 in the exhaust path L1 and the denitration catalyst has fine gold particles.
