Abstract

The invention provides a nuclear power plant heating system and a heating method thereof. The heating system comprises a condenser, a heating loop, a steam generator, a steam turbine, a steam-water separation reheater which are connected in sequence and a heating loop connected to the outlet of the steam-water separation reheater, wherein the steam turbine comprises a high-pressure cylinder, a medium-pressure cylinder and at least two low-pressure cylinders; the heating loop is used for heating the condensed water generated by the condenser for multiple times, the steam generator is used for heating the heated condensed water into saturated steam, and a part of saturated steam enters the high-pressure cylinder and expands and works; the steam-water separation reheater is used for removingwater in exhausted steam discharged after working, and heating the exhausted steam into superheated steam; and a part of superheated steam enters the middle-pressure cylinder and the low-pressure cylinder to expand and do work, and the other part of superheated steam enters the heating loop to heat the heating water and is supplied to the user. According to the nuclear power plant heating system and the heating method thereof, the environmental pollution problem caused by heating of a thermal power plant can be avoided, and the nuclear power plant heating system and the heating method have thegood technical effect.

Description

Technical field [0001] The invention relates to the technical field of nuclear power heating, in particular to a nuclear power plant heating system and a heating method thereof. Background technique [0002] At present, the problem of atmospheric haze during the winter heating season in northern my country is prominent, which has become a hot issue affecting people's livelihood and national image. Coal-fired heating is one of the main reasons for the formation of haze. In northern cities with central heating, coal-fired heating will cause a dramatic increase in sulfur dioxide and dust particles in the air. Weather conditions such as low temperature and low wind make the accumulation of haze impossible. Dispersion, leading to long-term haze weather in northern areas, urgently need to promote clean heating. At the same time, with the increasing peak-to-valley difference of grid load, the situation of power system peak shaving is getting more and more severe. Due to the increase i...
