Industrial coal - fired boiler pollution problems or can be resolved

    "High-performance micro-emission integrated powder fuel industrial boiler system" technology application research review will be held in Beijing recently, experts on Fujian Yongheng Energy Co., Ltd. related technical processes, energy efficiency, emissions and other technical review. Experts believe that if the technology of energy-saving emission reduction effect in a number of scenes (different coal quality, different levels of boilers, different operating load) to practice, will solve the problem of pollution of industrial coal-fired boiler to promote the role.

    In recent years, China's energy consumption is facing enormous environmental protection and emission reduction pressures. Efficient and efficient coal-fired boiler for energy efficient, clean emissions and other characteristics, as the country to promote the focus of energy-saving technology projects. Eternal energy "coal-fired industrial boiler flue gas desulfurization and denitrification technology" was selected in the Ministry of Environmental Protection in 2014 to encourage the development of environmental protection technology directory, "new efficient pulverized coal boiler system technology" finalists of the National Development and Reform Commission national key energy-saving low-carbon technology promotion table of Contents.

    It is understood that the technical process of environmental protection burning sulfur content of 0.3% to 0.5% of low-sulfur coal, the use of bottom-type swirl burner to achieve low nitrogen combustion, flue dust bag into the wet desulfurization system, desulfurization After the flue gas discharge standards. In the China Special Equipment Testing and Research Institute of Jinan Jiyang County Sun Geng town Dali Food Co., Ltd. installed using the technology 14 megawatts of high efficiency pulverized coal steam boiler issued by the energy efficiency test report and environmental test report, we can see the operating load The NOx efficiency was 89.49%, the concentration of sulfur dioxide was 35.15 mg / m3, and the NOx emission concentration was 92.61 mg / m 3, which was in accordance with the relevant national environmental protection standard.

    At the meeting, representatives from Eternal Energy introduced the basic situation and application of the review technology, and introduced the technical practice with Jinan Dali Food Group Co., Ltd. (the only 20 ton grade coal-fired boiler enterprise in Jinan area) Application of the situation. The expert group conducted a question and discussion on the level of energy efficiency, environmental impact, operating cost, technical rationality, safety hazard, policy compliance, promotion and application of technical suggestions, and provided the expert opinions of the expert group.

    Wang Yinhong, founder and chairman of the Treasure Island, said that if the expert review, the technology can help boost the industrial coal-fired boilers to further enhance the energy saving and environmental protection, Treasure Island is willing to actively promote the country's energy conservation and environmental protection undertakings responsibility.

    The review will be held by the Treasury Island, the National Energy Conservation Center, Xi'an Jiaotong University, China Special Equipment Testing Research Institute, China Environmental Science Research Institute, Zhejiang Province Energy Monitoring Corps, North China Electric Power University and other units to participate.
