Abstract

The invention relates to a combined heat and power generation system and method provided with an absorption heat pump and a steam ejector, the combined heat and power generation system comprises a steam turbine, a heater, a deaerator, the absorption heat pump and a steam ejector, the combined heat and power generation system is combined with the absorption heat pump, steam of the steam turbine is used as a heat source, and the steam ejector is used for ejecting steam. The heat supply capacity of the combined heat and power generation system is improved, and thermoelectric coupling of the combined heat and power generation system is relieved to a certain extent; meanwhile, the steam injection device is introduced to heat the return water of the heat supply network for three times, so that the heat utilization rate of the steam of the steam turbine is improved, the heating end difference is reduced, and the available energy loss caused by heat exchange is reduced.

Description

technical field [0001] The invention relates to the technical field of cogeneration, in particular to a cogeneration system equipped with an absorption heat pump and a steam ejector. Background technique [0002] In recent years, my country's industrial heat supply has continued to grow. China is a big coal-burning country. For a long time in the future, clean coal-fired district heating will still be the most effective way to balance environmental protection and cost pressure and achieve low-carbon heating. The cogeneration unit bears the electrical load and also bears the industrial and residential heat load in winter. When the traditional thermal power plant heats the residential heating water, the extraction steam directly heats the residential heating water. The temperature of the residential heating water is relatively low. The temperature of the heat exchange end is much higher than the temperature of the residential heating water. The large heating temperature differ...
