System for conducting combined supply of steam, thermal and electricity by utilizing nuclear energy

Abstract

The invention provides a system for conducting combined supply of steam, thermal and electricity by utilizing nuclear energy. The system for conducting combined supply of the steam, the thermal and the electricity by utilizing the nuclear energy comprises a steam generator secondary side loop, a heat supplying loop and an industrial steam supplying loop. A part of main steam generated by a steam generator is used for generating electricity, another part of the main steam or inlet steam of a low pressure cylinder of a steam turbine is led into the heat supplying loop, and the rest part of the main steam or extracted steam of a high pressure cylinder of the steam turbine is led into the industrial steam supplying loop; and a heating steam condensing water cooler is arranged in the steam generator secondary side loop, steam condensed water flows of the heat supplying loop and the industrial steam supplying loop are discharged into a steam condenser after passing through the heating steam condensing water cooler, and condensate water of the steam condenser passes through the equipment of a condensate polishing treatment device, the heating steam condensing water cooler and the like and returns back to the steam generator. According to the system for conducting combined supply of the steam, the thermal and the electricity by utilizing the nuclear energy, the multi-function of conducting combined supply of the steam, the thermal and the electricity by utilizing the nuclear energy is achieved, the thermal efficiency and the applicability of a nuclear power station are improved, and the safety of steam supplying and heat supplying by utilizing the nuclear energy is improved by adopting various technological methods.

Description

technical field [0001] The invention belongs to the technical field of nuclear energy, and in particular relates to a system for combined supply of steam, heat and electricity by using nuclear energy. Background technique [0002] As we all know, insufficient energy supply is an important factor restricting the development of our country's national economy. In areas where conventional energy is lacking, it is urgent to find alternative energy. As a safe, clean and economical energy, nuclear energy is one of the more mature alternative energy sources. In recent years, the heating and heating demand of urban residents has become one of the main market areas for the rapid growth of terminal heat consumption. On the other hand, the national energy-saving and emission-reduction policies have become increasingly stringent, and all cities and towns are required to actively eliminate existing small heating boilers. The “one increase and one decrease” of heat load and heat source, a...
