The invention relates to a multi-mode operation air pre-heater and a waste heat recycling garbage power generation system with the same. The system comprises a garbage incineration boiler, a steam turbine, a power generator, the steam air pre-heater and a heat exchanger. The garbage incineration boiler communicates with the steam turbine, and the steam turbine communicates with the power generator. The garbage incineration boiler communicates with a steam inlet of the steam air pre-heater to form a boiler steam passage, the steam turbine communicates with the steam inlet of the steam air pre-heater to form a steam turbine steam passage, an air outlet of the steam air pre-heater communicates with an inlet of the garbage incineration boiler, a drain port of the steam air pre-heater communicates with an inlet of the heat exchanger, and the heat exchanger is used for providing heat exchange for a user system. Steam with different parameters can be extracted to serve as a heating steam source according to the operating load of a unit, the operating mode of the air pre-heater is optimized, the output power of the steam turbine is increased, gradient utilization of energy is achieved, waste heat can be recycled and supplied to the user system, and the energy utilization efficiency of the system is effectively improved.
