One kind of lng / oxygen fuel MIXED direct power cycle power plant

One kind of LNG / oxygen fuel MIXED direct power cycle by the subsystem generator for power, regenerative cycle subsystem and liquid oxygen, and LNG supplied with CO2 capture subsystem; group combustion chamber at high pressure and reheat combustor Alternatively group and reheater boiler; after LNG / liquid oxygen and high pressure feed water temperature combustion products to produce a mixed H2O / CO2 mixed vapor expansion turbine power generation unit, the exhaust steam mixed refrigerant condensed water separated in the condenser, CO2 pre after cooling and liquefaction boosted. Due to the high pressure turbine and a working fluid inlet temperature, and a combustion control strategy adjustment unit load in the valley and the low pressure turbine electrical period splitting operation, can greatly improve the efficiency of the unit; size of energy storage in order to achieve zero CO2 and NOx emissions, high efficiency, peaking functions.
