China Announces "Implementation of Comprehensive Improvement Project for Energy Saving and Environmental Protection of Coal-fired Boilers"
Author: Date: 2018-11-01

The National Development and Reform Commission and other seven departments jointly prepared the "Energy Conservation and Environmental Protection Comprehensive Implementation Project for Coal-fired Boilers" on the 18th. The plan is clear. By 2018, promote 500,000 steaming tons of high-efficiency boilers, and increase the market share of high-efficiency coal-fired boilers from less than 5% to 40%. Eliminate 400,000 steaming tons of backward coal-fired boilers; complete 400,000 steaming tons of coal Energy-saving renovation of boilers.

At the same time, by 2018, it is necessary to promote the establishment of several high-efficiency boiler manufacturing bases and cultivate a group of large-scale high-efficiency boiler backbone enterprises; the average operating efficiency of coal-fired industrial boilers will increase by 6 percentage points on the basis of 2013 to form 40 million tons of standard coal per year. Energy saving capacity; reduce emissions of 1 million tons of smoke, 1.28 million tons of sulfur dioxide, 240,000 tons of nitrogen oxides.

China's boilers are mainly coal-fired. Among them, coal-fired power station boilers have approached foreign advanced levels in recent years, and coal-fired industrial boilers have great potential for energy saving and emission reduction. Data show that the annual emissions of soot, sulfur dioxide, and nitrogen oxides from coal-fired industrial boilers account for approximately 33%, 27%, and 9% of the country's total emissions, respectively. In recent years, the large-scale haze in China has been closely related to the characteristics of high-intensity and low-altitude emissions of coal-fired industrial boilers.

The plan proposes various measures. The first is to speed up the promotion of efficient boilers. At the same time, we will accelerate the elimination of backward boilers, 50,000 small coal-fired boilers in 2014, and 200,000 steam-tonned backward boilers from 2014 to 2015. Except for the necessary reservations, by the end of 2015, all coal-fired boilers with a capacity of 10 tons per hour or less will be phased out in Beijing-Tianjin-Hebei and surrounding areas of prefecture-level and above cities, and all coal-fired boilers in Beijing's built-up areas will be eliminated. Coal-fired boilers with a capacity of 10 tons per hour or less will be basically eliminated in built-up areas of cities at the first level and above.

The plan proposes that energy-saving retrofits should be strengthened, and by the end of 2017, energy-saving retrofits of in-use boilers with substandard energy efficiency will be basically completed. At the same time, to improve the level of boiler pollution control, newly built coal-fired boilers of less than 20 tons per hour are prohibited in built-up areas of cities at the prefecture level and above. In principle, no new coal-fired boilers of 10 tons per hour or less are allowed in other areas. In principle, no new coal-fired boilers can be built in the built-up areas of prefecture-level cities and above in Beijing, Tianjin, Hebei, Shanxi, and Shandong.

The plan also specified that new production and installation of coal-fired boilers of 20 tons per hour and above should be installed with high-efficiency desulfurization and high-efficiency dust removal facilities. To improve the desulfurization and dust removal level of in-use coal-fired boilers, coal-fired boilers of 10 tons per hour or more should be reformed with high-efficiency flue gas desulfurization and dust removal, and actively carry out demonstration demonstrations of low-nitrogen combustion technology transformation to achieve full compliance with emissions.
