Abstract

The invention discloses a nuclear gas combined steam supply system which comprises a nuclear energy steam supply unit, a waste heat boiler, a heating and deoxidizing unit and a gas turbine generator set. The nuclear energy steam supply unit comprises a steam generator; the heating and deoxidizing unit is connected between the waste heat boiler and a water inlet of the steam generator; a superheater is arranged in the waste heat boiler; an inlet of the superheater is connected with a steam outlet of the steam generator; and the gas turbine generator set is connected with the waste heat boiler, so that flue gas formed after combustible gas is combusted is conveyed into the waste heat boiler. According to the nuclear gas combined steam supply system provided by the invention, the steam exhausted by the steam generator of a low-temperature reactor is heated through flue gas waste heat, so that the external steam supply temperature is increased; and meanwhile, the flue gas waste heat is used for preheating water supplied by the steam generator of the low-temperature reactor, so that nuclear heat energy is saved, and the total external steam supply amount is increased.

Description

technical field [0001] The invention relates to the technical field of nuclear energy application, in particular to a nuclear gas combined steam supply system. Background technique [0002] Small nuclear reactors have the characteristics of multiple uses and a wide range of applications. From the perspective of energy forms, the application market of small onshore reactors mainly includes the following three aspects: [0003] 1) Provide steam: Steam is widely used in industrial industries and is the main form of energy demand in industrial industries. Typical application methods include: heating / disinfection / humidification, pneumatic / energy drive, refrigeration / cooling, cleaning, etc. [0004] 2) Provide hot water: hot water is mainly used for civil heating in winter in northern regions. In addition, it also has a good application space in the air conditioning system of large buildings and seawater desalination. [0005] 3) Providing electricity: Electricity is one of the ...
