Reheating power generation system located outside boiler and used for garbage power generation

The invention discloses a reheating power generation system located outside a boiler and used for garbage power generation. The reheating power generation system comprises the boiler, a steam turbinehigh-pressure cylinder, a reheating device, a steam turbine low-pressure cylinder, a condenser, a heating system, a feedwater pump and a high-pressure heating system which are sequentially communicated through a pipeline according to a steam circulation sequence. The steam turbine high-pressure cylinder is in transmission connection with the steam turbine low-pressure cylinder through a gearbox. The steam turbine low-pressure cylinder is in transmission connection with a generator. The reheating power generation system has the beneficial effects that the waste steam after work in the steam turbine high-pressure cylinder can be heated, the steam quality is improved, then the reheated steam is introduced into the steam turbine low-pressure cylinder to continue to do work, the humidity of thelast stages of a steam tu
