BIGCC solar thermal and BIGCC-integrated combined power generation system

摘要

The hybrid power generation system incorporating solar heat and BIGCC is composed of a solar collecting system (9), a biomass gasifier (1), an electricity generator (7) using gas fuel, a steam turbine (13) (14). The solar concentrate collection system 9 is connected to the solar energy heat exchange system 11. The biomass gasification apparatus 1 is connected to an electric generator 7 using gas as fuel through a gas compressor 3, a combustion chamber 5, and a gas turbine 6. The output of the gas turbine (6) is simultaneously connected to the gas remaining heat system (8). The low pressure steam output of the gas residual heat system (8) is connected to the medium / low pressure cylinder of the steam turbine (13). The high pressure steam output of the gas residual heat system 8 and the high pressure steam generated by the solar energy heat exchange system 11 are both connected to the steam mixing control system 12. [ The output of the steam mixing control system 12 is connected to the high pressure cylinder of the steam turbine 13. [ By using a steam mixing control system, mixing of steam at different temperatures is realized, and the temperature of the mixed steam is regulated and controlled to satisfy the steam condition of the variable parameter steam turbine.
