Coal-fired power generation isCyberspinscasinoThe most traditional and widely used way of power generation in China, in the orderly promotion of carbon peak, carbon neutralization process, coal-fired power plant energy saving and emission reduction and transformation and upgrading is of great significance.

The exhaust gas from coal combustion contains a large number of harmful substances, such as sulfur dioxide, nitrogen oxides, particles and so on. These pollutants are released into the atmosphere during coal combustion, which directly leads to the serious problem of air pollution, and affects the water body and soil through sedimentation and aerosol form.

In order to solve the "black crisis" caused by coal burning, on the one hand, it is imperative to promote the transformation of energy structure, on the other hand, we can also realize "waste utilization" and reduce the impact on the environment by purifying and utilizing coal-fired waste gas.

The demonstration project of the collaborative technology of waste heat utilization and ultra-net emission of a thermal power plant in Qingdao provides a new idea for solving the problem of coal-fired emission pollution.

The project introduces a new technology of deep recovery of waste heat from flue gas whitening in Tsinghua University, and adopts the process of "flue gas direct spray cooling + absorption heat pump + compression heat pump" to achieve ultra-low discharge of flue gas and wastewater. And under the witness of nearly 30 experts of the appraisal committee, including academician of the Chinese Academy of Engineering, vice chairman and secretary-general of the China Energy Research Association, it is concluded that "the project has made a major breakthrough in pollution reduction, carbon reduction and synergy in the field of cogeneration central heating, and the synergistic technology of waste heat utilization and flue gas ultra-net discharge, waste heat utilization and wastewater purification are all original. The overall achievement of the project has reached the international leading level, which is of great significance to the energy saving and emission reduction of coal-fired clean heating in northern China.

The measured data of the project show that the waste heat of flue gas can be deeply recovered by 400000 GJ per heating season, and raw coal can be saved by 19423.Cyberspinscasino. 6 tons, 43776.6 tons of carbon dioxide, 120 tons of sulfur dioxide, 59 tons of nitrogen oxides, 1332.2 tons of soot, 33000 tons of waste water, and 129000 tons of water saving. It is of high social, economic and technological value to provide a feasible demonstration template for the super-clean route of thermal power plants with lower energy costs and to promote the green action of super-net emissions of thermal power plants.

McVille screw heat pump unit is used for secondary waste heat utilization in this project to meet the heating needs of the project by converting low-grade energy from waste heat from thermal power plants into high-grade energy.
