Heating method
The temperature required for urban centralized heating is not high, and the existing nuclear technology is more satisfying. At present, there are three nuclear heating methods that are developing:
1 city centralized heating special low temperature heating stack. This stack of pressure is 1 to 2 MPa, which can output hot water for urban application of about 100 ° C. Due to the low installation of the reactor, it is possible to build in the suburbs of the city.
2 nucleating power station. It is similar to the principle of ordinary thermal power station, just replacing the mineral fuel boiler with a nuclear reactor. The reactor of the nucleating power plant is high, and the location of the residential area must be built in accordance with the location of the power station site, so that its development is limited to a certain extent. 3 Chemical heat pipe remote nuclear heat transfer system. Is the advanced technology being studied. It utilizes high temperature heat sources of 900 ° C from high temperature gas cooling, perform reversible reactions, and is sent to the user at room temperature, and in the regeneration (methanation) apparatus is generated, chemical heat is supplied. This approach can be used to deliver nuclear fever to a large area.
Economic Benefits
Due to the adoption of multiple seals and shielded measures, nuclear heat stacks, especially low temperature heating stacks are discharged to radioactive substances in the environment, even more than burning coal The boiler is much less. From an economic point of view, the initial investment of nuclear heat heap is higher than the burning coal boiler, but the fuel fee is more province, compared with the coal boiling coal boiler with power, only about 100,000 yuan of coal. It can output hot water from 100 ° C for urban application. More than the fuel costs of the boiling oil boiler are lower. Some countries have begun to develop nuclear fences. More than ten kinds of pumping heat is implemented in a nuclear power plant.
Nature: Nuclear Supply Heat is a nuclear energy system that is dominated by an output. Can be used for the heating and comprehensive utilization of urban residents. As a supplement of nuclear power, its promotion application helps to improve energy structure, reduce greenhouse gases and improve towns. Nuclear heat heap has a good natural safety, simple system, reliable operation, can be built close to the dense area of the residents, saving the expensive fees for highlighting distance delivery. The first 5MW nuclear heating test in the world is built and running in 1989. The results show that nuclear heat heaps developed by China have excellent performance.
