Embodiment Construction

[0033] In order to understand the technical features, objects and effects of the present invention, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0034] Such as figure 1 , 2 As shown, the plurality of complementary duck systems of the present invention include nuclear energy supply vehicle units, waste heat boilers 30, gas turbine generator sets 40, and biomass gas supply unit 50.

[0035] The nuclear energy supply vehicle includes a steam generator 10, a pressure vessel 20 connected to the steam generator 10, and the steam generator 10 and the pressure vessel 20 are also part of the nuclear island system. The steam generator 10 is connected to the remaining heat boiler 30, and the steam is delivered to the remaining heat boiler 30, and the waste heat boiler 30 is used to form a low pressure superheated steam (such as ≥221 ° C) using the remaining heat boiler 30. After the transportation to the steam pipe n...

Abstract

The invention discloses a multi-energy complementary steam supply system which comprises a nuclear energy steam supply unit, a waste heat boiler, a gas turbine generator set and a biomass gas supply unit. The nuclear energy steam supply unit comprises a steam generator, and an economizer and a superheater are arranged in the waste heat boiler; and the economizer is connected with a water inlet of the steam generator through the deaerator, and heated and deoxygenated demineralized water is conveyed into the steam generator. An inlet of the superheater is connected with a steam outlet of the steam generator; the gas turbine generator set is connected with the waste heat boiler, and flue gas formed after combustion of the combustible gas is conveyed into the waste heat boiler; and the biomass gas supply unit is connected with the gas turbine generator set and provides combustible gas for the gas turbine generator set. According to the multi-energy complementary steam supply system, the steam exhausted by the steam generator of the low-temperature reactor is heated through flue gas waste heat, the temperature of supplied steam is increased, meanwhile, the flue gas waste heat is used for preheating supplied water of the steam generator of the low-temperature reactor, nuclear heat energy is saved, and the total external steam supply amount is increased.

Description

Technical field [0001] The present invention relates to the field of nuclear energy applications, and more particularly to a plurality of complementary panervifun system. Background technique [0002] Nuclear energy small stack has a number of applications, wide application range, from the perspective of energy form, the application market in land small piles mainly have the following three aspects: [0003] 1) Provide steam: steam is widely used in the industrial industry. It is the main form of energy demand in the industrial industry. Typical applications are: heating / disinfection / humidification, moving gas / energy drive, cooling / cooling, cleaning, etc. [0004] 2) Provide hot water: hot water is mainly used in the winter of winter in the north. In addition, there is a good application space in the air conditioning system, seawater of large buildings. [0005] 3) Power: Electricity is one of the most widely used energy forms, play an important role in work and life. [...
