Abstract

The invention discloses a steam boiler system with a power generation function and a work method thereof. A high-pressure water pump of the system is connected with a boiler water inlet pipe of a pipe type boiler; a boiler steam output pipe of the pipe type boiler is connected with a steam turbine; the steam turbine is connected with a power generator and a steam turbine steam exhaust pipe; the steam turbine steam exhaust pipe is connected with a flue gas superheater which is connected with a flue gas waste heat recovery device through a low-temperature flue gas pipe; the flue gas waste heat recovery device is further connected with an input water pipe, a waste heat water pipe and a flue gas exhaust pipe; the waste heat water pipe is connected with the high-pressure water pump in a circulation manner; the pipe type boiler is further connected with the flue gas superheater through a boiler flue gas pipe; the flue gas superheater is connected with a condensate water pump through a condensate water pipe; and the condensate water pump is connected with the flue gas superheater through a spraying water pipe. By means of segmented utilization and stair utilization of energy of the steam boiler system with the power generation function, in the process that low-grade heat energy is supplied, phase change expansion caused by heating is fully utilized, high-grade energy is output preferentially, and comprehensive and efficient utilization of energy is achieved.

Description

technical field [0001] The invention relates to the technical field of steam boilers, in particular to a steam 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, those skilled in the art are devoting themselves to developing a steam boiler system with power generation function. Contents of the invention [0004] In view of the above-mentioned defects in the prior art, the technical problem to be solved by the present invention is to provide a steam boiler system with power generation function and its working method, through the segmental utilization and step utilization of energy, in the process...
