The utility model discloses a boiler power generation system which comprises a first medium cold tank, a first medium cold pump, a boiler, a first medium hot tank, a first medium heat pump, a first heat exchanger and a second heat exchanger which are sequentially connected through a first medium loop, wherein the second heat exchanger is arranged on the smoke side of the boiler. A first medium in the first medium cold tank is pressurized through a first medium cold pump, then enters a second heat exchanger on the smoke side of the boiler, absorbs smoke heat at the position of the second heat exchanger, then is heated and enters the first medium hot tank to be stored, and the first medium in the first medium hot tank exchanges heat with condensed water in a condensed water system. The heated condensed water enters the water supply side of the boiler, and the first medium with the temperature reduced continues to enter the boiler to absorb smoke heat, so that the amount of steam entering a turbine from a boiler
