The invention discloses a fuel and power complementing type heating peak regulation system used for a heating station. The system comprises a natural gas boiler, a water storage tank and a plate typeheat exchanger; a smoke heat exchanger is arranged in a flue of the natural gas boiler, a working medium liquid storage tank and a throttling valve are connected between a tube pass inlet of a smoke heat exchanger and a fluid outlet of the plate type heat exchanger, a working medium pump is in parallel connection between an inlet and an outlet of the throttling valve, a first working condition switching valve is connected between a tube pass outlet of the smoke heat exchanger and a fluid inlet of the plate type heat exchanger, a compressor and a second working condition switching valve are connected between t he tube pass outlet of the smoke heat exchanger and an inlet of a gas and liquid separator, and a third working condition switching valve is connected between an outlet of the gas andliquid separator and the fluid inlet of the plate type heat exchanger. Under the heating station peak regulation working condition, an organic working medium heat circulation system is matched with the natural gas boiler to jointly run, and through the fuel and power complementing manner, the heating cost is reduced.
