POWER GENERATION SYSTEM AND METHOD COMBINING FOSSIL FUEL BOILER WITH HIGH-TEMPERATURE GAS-COOLED REACTOR

A power generation system combining a fossil fuel boiler with a high-temperature gas-cooled reactor. The system comprises a fossil fuel boiler (1), a high-temperature gas-cooled reactor (2), a steam turbine (3), a power generator (4), and an auxiliary machine system (5), wherein the fossil fuel boiler (1), the high-temperature gas-cooled reactor (2), the steam turbine (3) and the auxiliary machine system (5) are sequentially connected in a flow direction of a medium; a steam exhaust port of a high-pressure cylinder (31) of the steam turbine (3) is connected to the high-temperature gas-cooled reactor (2); and the steam turbine (3) is connected to the power generator (4), and steam from the fossil fuel boiler (1) is output as saturated steam or superheated steam. The system combines two heating power types of the fossil fuel boiler and the high-temperature gas-cooled reactor, and uses high-level, intermediate-level and low-level steam turbines, which is beneficial to improving initial parameters of the steam an
