Example Embodiment

[0022] In order to make the purpose, technical solution and technical effect of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific implementations described in this specification are only for explaining the present invention, not for limiting the present invention.

[0023] Please refer to figure 1 In the steam-water flow chart of the secondary circuit of the nuclear power plant shown, the condensed water produced by the condensation of the condenser passes through the shaft seal heater, No. 1 heater, No. 2 heater, No. 3 heater, No. 4 heater, and deaerator in sequence , No. 6 heater and No. 7 heater enter the steam generator. As a heat exchange device, the steam generator heats condensed water into saturated steam (this part of saturated steam is hereinafter referred to as main steam). A steam turbine consists of a high...

Abstract

The invention discloses a nuclear power heating heat source system which comprises a steam turbine high-pressure cylinder, a heat exchanger connected with the steam turbine high-pressure cylinder through a high-pressure cylinder steam exhaust pipe and a valve and a heat supply network, wherein heat supply network circulating water in the heat supply network flows through the heat exchanger and is heated by exhaust steam of the high-pressure cylinder. Compared with the prior art, the nuclear power heating heat source system uses the exhaust steam of the steam turbine high-pressure cylinder as a heating heat source, the steam acts in the steam turbine high-pressure cylinder, and therefore the heat efficiency of a nuclear power plant can be effectively improved, and the environmental pollution problem of thermal power heating is avoided. In addition, drainage from the heat exchanger to a condenser can improve the temperature of condensed water, so that the efficiency of the nuclear power plant is improved, heat supply of the nuclear power plant and peak regulation operation of the nuclear power plant are realized.

Description

technical field [0001] The invention belongs to the technical field of nuclear power, and more specifically, the invention relates to a nuclear power heating heat source system. Background technique [0002] Coal-fired heating is one of the most important factors leading to winter smog. In northern cities with centralized heating, coal-fired heating will lead to a sharp increase in sulfur dioxide and dust particles in the air. Meteorological conditions such as low temperature and low wind make the smog accumulate and linger, resulting in long-term smog in the northern region, which has become a hot issue affecting the national economy, people's livelihood and the country's image. In addition, harmful substances produced by burning coal for heating include carbon dioxide and sulfur dioxide. Carbon dioxide is the main substance of the greenhouse effect, and sulfur dioxide is easy to form acid rain. Therefore, coal-fired heating will bring serious environmental pollution probl...
