Abstract
The invention discloses an industrial steam production system for a pressurized water reactor nuclear power unit. The system comprises: a nuclear steam supply device, which is a pressurized water reactor nuclear power unit used for supplying heat source steam to an industrial steam production device while generating power; the industrial steam production device, an inlet of which is connected withan outlet of the nuclear steam supply device, wherein heat source steam exchanges heat with feed water introduced into the industrial steam production device, and the feed water is heated by the heatsource steam to generate industrial steam with preset parameters to be conveyed to a heat user. According to the invention, the pressurized water reactor nuclear power unit is used as a support, secondary loop main steam of the pressurized water reactor nuclear power unit is used for producing industrial steam through an industrial steam production device, the steam is conveyed to a user througha steam pipe network, thus realizing the application of externally supplying clean industrial steam by the nuclear power station, developing a new way for comprehensive utilization of nuclear energy,effectively solving the environmental pollution caused by traditional energy sources like coal, improving the energy structure, guaranteeing the industrial development steam demand, and improving theeconomic benefits of the nuclear power station.
Description
technical field [0001] The invention belongs to the technical field of comprehensive utilization of nuclear energy, and in particular relates to an industrial steam production system used for pressurized water reactor nuclear power units. Background technique [0002] At present, my country's industrial steam supply is mainly based on thermal power plants and boiler rooms, and the fuel that can be used is still mainly coal, while coal-fired emissions of dust, sulfide, nitrogen oxides and carbon dioxide are responsible for air pollution, smog and greenhouses. main reason for the effect. With the increasing number of nuclear power units in my country and the continuous development of nuclear energy application technology, the multi-purpose application of nuclear energy, especially nuclear energy heating technology, has become relatively mature. Many nuclear power units at home and abroad have adopted cogeneration to provide heat for regional residents. However, At present, ther...
