Embodiment 1
[0047] Such as figure 1 As shown, a schematic flow chart of an external combustion Breton combined cycle power generation device with solar heating of the present invention.
[0048] A Britton combined cycle power generation device with solar heating, which uses the high-temperature air discharged from the turbine in the top Bretton cycle of the external combustion type as the heat source of the bottom Bretton cycle, and recovers the flue gas discharged from the top cycle The waste heat is heated up by the cavity receiver of the solar heat concentrator, and then used for bottom cycle power generation, thus forming an external combustion Breton combined cycle power generation system with solar heating.
[0049] The top Breton cycle refers to that the combustion air 10 is pressurized by the top cycle compressor 11 to form top cycle compressed air 12, which is sent to the heat exchanger 14, and the formed top cycle high temperature air 15 is sent to the top cycle turbine 16 , dr...

The invention relates to an external-combustion type Britten combined cycle power generation device. The external-combustion type Britten combined cycle power generation device combines a top Britten circulating operation mode and a bottom Britten circulating operation mode and uses high-temperature air discharged from a turbine in the top Britten circulation of the external combustion type as a heat source of the bottom Britten circulation. Bottom circulation adopts air as working medium, waste heat of gas discharged by the top circulating turbine is recovered, and the air is heated by a cavity receiver of a solar heat accumulator and used for bottom Britten circulating power generation. By the external-combustion type Britten combined cycle power generation device, fuel selection range is enlarged, heat energy generated by combustion is more reasonably utilized, safety of a turbine is ensured, solar heat is effectively utilized, energy is saved and consumption is reduced. The external-combustion type Britten combined cycle power generation device is particularly applicable to the water-deficient area.
