The invention discloses a heating boiler system with a power generation function and a working method of the heating boiler system. A high-pressure water pump of the heating boiler system is connected with a boiler water inlet pipe of a tubular boiler; a high-pressure steam pipe of the tubular boiler is connected with a jet pump; the jet pump is connected with a steam turbine through a working steam pipe; the steam turbine is separately connected with a generator and a dead steam pipe; the dead steam pipe is connected with a condensing heat exchanger; the top part of the condensing heat exchanger is provided with an uncondensed steam exhaust head; the condensing heat exchanger is separately connected with a condensate pipe, an uncondensed steam pipe and a heat supply water outlet pipe; the uncondensed steam pipe is connected with a return extraction steam pipe through an air return valve; a boiler flue gas pipe of the tubular boiler is connected with a flue gas regenerator; the flue gas regenerator is connected with the condensing heat exchanger through a return water reheating pipe; and the flue gas regenerator is also separately connected with a heat supply water return pipe and a flue gas exhaust pipe. According to the heating boiler system disclosed by the invention, in a process of supplying low-grade heat energy, high-grade energy is output preferentially by fully utilizing phase change expansion caused by a heating process, and therefore comprehensive efficient utilization of the energy is realized.
Description
technical field [0001] The invention relates to the technical field of heating furnaces, in particular to a heating boiler system with power generation function and its working method. Background technique [0002] General power plants are designed for the purpose of power generation, and the waste heat generated by power generation is very large, so that it cannot be effectively used; because the boiler does not use the heating process, it cannot realize the step-by-step utilization and high-efficiency utilization of energy. [0003] Therefore, it is necessary to design a heating boiler system with power generation function and a method thereof. Contents of the invention [0004] In view of the above-mentioned defects of the prior art, the present invention provides a heating boiler system with power generation function and its working method. In the process of providing low-grade heat energy supply, the phase change expansion caused by the heating process is fully utiliz...
