Non-reheat parallel power generation system of nuclear energy and conventional energy

Abstract

The invention discloses a no-heating parallel-connected power generation system of nuclear energy and conventional energy sources. The no-heating parallel-connected power generation system of the nuclear energy and the conventional energy sources comprises a turbine generator set, a heat exchanger, a nuclear reactor, a heating device and a high pressure heater. The turbine generator set comprises a steam turbine and a power generator, the steam turbine is connected with the power generator and drives the power generator to generate electricity. The heat exchanger is connected with the turbine generator set. The nuclear reactor is connected with the heat exchanger, and steam generated from the nuclear reactor heats part of backwater coming from the turbine generator set through the heat exchanger. The heating device is connected with the heat exchanger and turbine generator set and used for heating steam coming from the heat exchanger and then supplying the steam to the turbine generator set through the conventional energy sources. The high pressure heater and the heat exchanger are in parallel connection between the turbine generator set and the heating device, the high pressure heater heats the rest backwater coming from the turbine generator set. The power generation system has better economical efficiency and wider application space, and energy consumption and pollution are reduced.

Description

technical field [0001] The invention relates to the technical field of nuclear energy application and conventional energy application technology, in particular to a non-reheat parallel power generation system of nuclear energy and conventional energy. Background technique [0002] Due to the limitation of the outlet steam temperature of the steam generator, the existing pressurized water reactor nuclear power plant can only produce low-quality steam to enter the steam turbine for power generation, so the power generation efficiency is only about 33%, while the conventional power unit of the same scale can use more For high-quality steam, the efficiency can reach more than 45%. For example, the temperature of the main steam of an ultra-supercritical conventional motor unit can reach 600°C, and the efficiency can reach 49% or even higher. [0003] Thermal power generation is currently the main source of conventional power supply, and the corresponding units have mature technol...
