The reporter learned from the national energy group that the National Energy Group officially released the mixed ammonia combustion technology of coal-fired boilers on the 24th. The technology has passed the technical review organized by China Electrical Engineering Society and China Petroleum and Chemical Industry Federation, and has been successfully put into operation in Yantai, Shandong Province. It is reported that the carbon dioxide emission of coal-fired power generation is huge, accounting for about 40% of China's total carbon dioxide emission. Reducing the carbon dioxide emission of coal-fired power generation is an important work for China to successfully achieve the goal of carbon peak and carbon neutralization. Yue Guangxi, academician of the Chinese Academy of engineering, believes that this technology has broken through the bottleneck of green ammonia in carbon reduction and NOx emission reduction of pulverized coal boilers, and explored a new path other than carbon capture and storage for China's coal-fired units to achieve significant carbon emission reduction in the future. "In the future, energy development should be transformed into clean fossil energy, large-scale clean energy and comprehensive energy, in which flexible power generation technologies such as mixed ammonia combustion play an important role." Liu Jizhen, academician of the Chinese Academy of engineering, said. Li Shousheng, President of China Petroleum and Chemical Industry Federation, believes that the development of mixed ammonia combustion technology in coal-fired boilers has opened up a new path for the diversification of thermal power fuels and created a new market for the utilization of synthetic ammonia. "We hope to accelerate the application and promotion of this technology in thermal power and industrial fields, give full play to the technical advantages brought by mixed ammonia combustion, promote the clean and efficient utilization of energy in China, and provide technical support for achieving the goal of carbon peak and carbon neutralization." An Hongguang, vice president of China Electricity Council, said. "This technology has realized the industrial application of mixed ammonia combustion on 40mW coal-fired boiler with a 35% mixed combustion ratio for the first time. It has independently developed a flexibly adjustable mixed ammonia low nitrogen pulverized coal burner and equipped with a multivariable adjustable ammonia supply system, which has realized the effective control of ammonia burnout rate of 99.99% and nitrogen oxides, providing a basic number for the industrial application of mixed ammonia combustion system of higher-grade coal-fired boiler And technical solutions. " According to the relevant person in charge of Yantai Longyuan Power Technology Co., Ltd. affiliated to the national energy group, this technology can be applied to coal-fired boilers in power generation, industry and other fields. Through the low-cost mixed ammonia combustion transformation of existing coal-fired boilers, the significant carbon dioxide emission reduction of coal-fired units can be realized. (outlook new era)
