Abstract

The invention discloses a disc type solar-fuel gas and steam combined cycle power generation system. The system comprises a disc type solar system and a fuel gas and steam combined cycle power generation system. The disc type solar system comprises a disc type solar heat collection field and a central heat exchanger. The fuel gas and steam combined cycle power generation system comprises a fuel gas turbine generator unit, a waste heat boiler and a steam turbine generator unit. The disc type solar-fuel gas and steam combined cycle power generation system takes full advantages of high efficiency brought by disc type high parameters, thereby improving overall efficiency, saving energy and reducing environmental pollution.

Description

technical field [0001] The invention belongs to the field of power generation, in particular to a dish-type solar-gas-steam combined cycle power generation system. Background technique [0002] Solar thermal power generation has been widely valued because of its energy saving and environmental protection, but the pure solar thermal power generation system has been hindering its further commercialization process because of its high initial investment and low thermal performance. The composite thermal power generation system combining solar energy and fossil energy takes advantage of the large power adjustment range of fossil fuel units, eliminating the need for expensive heat storage systems and steam turbine systems in independent solar thermal power plants, thereby reducing power generation costs and achieving continuous and stable power generation dual purpose. At the same time, the solar thermal power generation system uses heat as an intermediate energy carrier, and it ...
