Embodiment Construction
[0019] A cogeneration system based on large-scale commercial nuclear power units of the present invention will be described in detail below with reference to the drawings and embodiments.
[0020] The cogeneration system based on large-scale commercial nuclear power units of the present invention includes a nuclear steam supply system 1, which has a nuclear reactor 101, a main pump 102 and a steam generator 103 connected in sequence through pipelines, and the nuclear reactor 101 Used to heat the coolant circulating in the nuclear steam supply system 1 . The main pump 102 is used to provide power for the closed cycle in the nuclear steam supply system 1 . The steam generator 103 is used to generate steam using high temperature coolant. The high-temperature coolant heated by the nuclear reactor 101 flows out from the coolant outlet of the nuclear reactor 101, flows into the coolant inlet of the steam generator 103 through a pipeline, flows out from the coolant outlet of the ste...

The invention belongs to the technical field of nuclear power heating, and particularly relates to a large-size commercial nuclear power unit based heat and power cogeneration system. The heat and power cogeneration system includes a nuclear steam supply system, a generation loop, a bled steam supply loop, and a heat supply network circulation water loop; the nuclear steam supply system is used for supplying steam; the generation loop is used for using part of the steam to generate power; the bled steam supply loop is used for extracting the other part of steam from the generation loop and performing heat exchange with the heat supply network circulation water loop; and the heat supply network circulation water loop is used for exchanging heat between the bled steam supply loop and the user heat supply network, and transmitting heat in the bled steam supply loop to the user heat supply network to achieve nuclear steam heating. The technical problem of environment pollution due to the conventional coal and gas heating plants can be solved; the bled steam from the nuclear power plant is used to perform heating, and the problem of environment pollution due to the conventional coal and gas heating plants can be prevented.
Description
technical field [0001] The invention belongs to the technical field of nuclear power heating, and in particular relates to a cogeneration system based on large-scale commercial nuclear power units. Background technique [0002] At present, the vast majority of urban heating plants in northern my country use coal and natural gas as their main fuels. Coal-fired heating plants will emit dust, sulfide, nitrogen oxides, and carbon dioxide due to coal combustion. These emissions will cause pollution to the atmospheric environment, causing smog and the greenhouse effect. Although natural gas heating plants only emit carbon dioxide, carbon dioxide is also one of the main culprits causing the greenhouse effect. [0003] The number of nuclear power units that have been built and are under construction in northern my country is increasing. Local governments hope that nuclear power plants can undertake more local public service obligations while producing electricity, and the realizati...
