Abstract

The invention discloses a high-heat-to-power-ratio combined heat and power generation system of a nuclear power unit, and a working method of the combined heat and power generation system. The high-heat-to-power-ratio combined heat and power generation system comprises a reactor, a steam heat exchanger, an absorption heat pump and a heat supply network heater, wherein a gas outlet of the reactor is connected with a hot-end inlet of the steam heat exchanger, a hot-end outlet of the steam heat exchanger is connected with a high-temperature heat source end inlet of the absorption heat pump, a high-temperature heat source end outlet of the absorption heat pump is connected with a hot-end inlet of the heating network heater, a cold end of the heating network heater is connected with heating network water, a hot-end outlet of the heating network heater is connected with a low-temperature heat source end inlet of the absorption heat pump, and a low-temperature heat source end outlet of the absorption heat pump is connected with a gas inlet of the reactor. According to the invention, the temperature of steam entering the reactor is reduced, and heat energy utilization efficiency is improved.

Description

Technical field [0001] The present invention belongs to the field of nuclear power supply, involving a thermoelectric unit thermoelectric construction system for large thermoelectric ratio and its working methods. Background technique [0002] Nuclear electric heating is a nuclear energy system mainly based on output. It can be used for the heating and comprehensive utilization of urban residents. As a supplement of nuclear power, its promotion applies help to improve energy structures, reduce greenhouse gases and improve towns. Nuclear power supply has a good natural safety, simple system, reliable operation, can be built close to the residential dense area, saving the expensive cost of highlighting distance delivery. [0003] However, nuclear power supply has not yet been applied, mainly through the form of turfing, and the thermal electricity is relatively small. Inventive content [0004] SUMMARY OF THE INVENTION It is an object of the present invention to overcome the disad...
