Abstract:
A thermal power generation system includes: a boiler; at least one steam turbine; a generator; a condenser; at least one low-pressure feed water; a high-pressure feed water pump; at least one high-pressure feed water heater capable of heating water pumped by the high-pressure feed water pump by utilizing extracted steam; a catalyst device including at least one kind of catalyst capable of promoting reduction reaction of nitrogen oxide and oxidation reaction of metallic mercury, the nitrogen oxide and the metallic mercury both being contained in the exhaust gas; at least one mercuric oxide removing device capable of removing mercuric oxide produced by the oxidation reaction of the metallic mercury from the exhaust gas; and an exhaust gas temperature adjustment device capable of adjusting a temperature of the exhaust gas at the catalyst device, by adjusting heating of the water by the at least one high-pressure feed water heater.

Claim (Index 1):
A thermal power generation system, comprising:\n a boiler including at least one internal heat exchanger being disposed in a circulation passage through which water is circulatable, and being capable of generating steam through heat exchange between the water and exhaust gas produced by burning fuel; at least one steam turbine being disposed in the circulation passage and being capable of outputting power by utilizing the steam; a generator capable of generating electric power by utilizing the power outputted from the steam turbine; a condenser capable of condensing the steam discharged from the steam turbine; at least one low-pressure feed water heater being disposed in a feed water path forming a part of the circulation passage, extending from the condenser to the at least one internal heat exchanger, and being capable of heating the water condensed by the condenser by utilizing steam extracted from the at least one steam turbine; a high-pressure feed water pump being disposed in the feed water path of the circulation passage so as to be positioned downstream of the at least one low-pressure feed water heater, and being capable of increasing a pressure of the water heated by the at least one low-pressure feed water heater and pumping the water; at least one high-pressure feed water heater being disposed in the feed water path of the circulation passage so as to be positioned between the high-pressure feed water pump and the at least one internal heat exchanger, and being capable of heating the water pumped by the high-pressure feed water pump by utilizing steam extracted by the at least one steam turbine; a catalyst device being disposed in an exhaust path of the exhaust gas extending from the boiler, and including at least one kind of catalyst capable of promoting reduction reaction of nitrogen oxide and oxidation reaction of metallic mercury, the nitrogen oxide and the metallic mercury both being contained in the exhaust gas; at least one mercuric oxide removing device being disposed in the exhaust path so as to be positioned downstream of the catalyst device, and being capable of removing mercuric oxide produced by the oxidation reaction of the metallic mercury from the exhaust gas; and an exhaust gas temperature adjustment device capable of adjusting a temperature of the exhaust gas at the catalyst device, by adjusting heating of the water by the at least one high-pressure feed water heater.
