At present, coal power is still the main energy in China, with a large total installation capacity，which is difficult to be completely replaced in a short time. In the future, the technical standard for efficient and clean combustion of coal-fired power plants is low carbon emissions. At present, Dual Carbon Strategy has become a part of the construction of national ecological civilization, and coal power generation is in urgent need of carbon capture, utilization and storage (CCUS) technology suitable for future demand. However, in China, CCUS equipment has been put into operation in ultra-low emission power plants, and there are common problems such as high capture cost and limited utilization of products. CCUS technology with low development cost and effective utilization of captured products is a common demand for electric power environmental protection. To this end, the paper put forward coal power CCUS technology future development direction should be the integration of flue gas pollutants coupling control, such as the application of plasma oxidation technology, the first oxidation reducing pollutants SO2 in flue gas, NO, etc., and then for ammonia absorber synergy desulfurization denitrification decarburization, overall pollutant removal process is simple, by-products has broad space for chemical conversion. Then, it is proposed that stable ammonia source supply can guarantee the implementation of the above integrated removal, and it is possible for coal power plants to provide more abundant product lines (ammonia energy, fertilizer, chemical products, etc.) in the future by building a self-sufficient ammonia production process.
