Household garbage incineration waste heat boiler steam reheating system adopting main steam for heating

The utility model relates to a steam reheating system capable of improving energy utilization efficiency by improving steam parameters of a garbage incinerator. The household garbage incineration waste heat boiler steam reheating system adopting main steam heating comprises a waste heat boiler, a superheater, a steam reheater, a steam-water separator, a steam turbine high-pressure cylinder, a steam turbine low-pressure cylinder, a condenser, a deaerator, a water feeding pump and the like. Boiler main steam enters a steam turbine high-pressure cylinder and a steam reheater in two ways. Main steam enters the steam-water separator after acting on the turbine high-pressure cylinder, separated water enters the deaerator, the steam enters the steam reheater and exchanges heat with the other pathof main steam, and reheated superheated steam is introduced into the turbine low-pressure cylinder to act. According to the system, the energy utilization efficiency of the garbage incinerator is improved, corrosion of a ste
