There are two main hazards of coal-fired boilers, one is the environmental hazard caused by soot and sulfur dioxide emitted by coal-fired boilers, and the other is the health hazard caused by pollutants discharged from coal-fired boilers. The users of coal-fired boilers are mostly small units and small enterprises. Due to the consideration of operating costs, inferior coal is often used. Without desulfurization, denitrification and even dedusting equipment, it is directly discharged into the atmosphere, which is causing a large range of haze weather. One of the important reasons is that the state requires that small coal stoves must be treated. On November 6, 2014, the seven ministries and commissions issued a coal-fired boiler renovation plan to completely phase out and prohibit the construction of coal-fired boilers of less than 10 tons/hour.

In order to effectively carry out air pollution prevention and control work, Yangzhou City resolutely won and won the "blue sky defense war" and ensured that the air quality improvement target was achieved on schedule. Based on the research, in the "1818 Air Pollution Prevention and Control Work Plan of Yangzhou City", Develop this work programme.

1. Strictly control the total amount of coal consumption. Strictly implement the “Work Plan for Reducing Coal Consumption in Yangzhou City in 2018”, and implement coal reduction and replacement for new, rebuilt and expanded coal-consuming projects. The coal consumption of enterprises above designated size in the city is controlled at ≤10 million tons, which is ≥600,000 tons less than 2016. Reduced coal consumption should be managed in a list, which is verifiable and measurable.

2. Carry out special rectification of coal-fired industrial furnaces. Formulate and implement the “Special Remediation Plan for Coal-fired Industrial Kilns in Yangzhou City”, organize a comprehensive investigation of the coal-fired industrial furnaces in the city, and register the coal-fired industrial furnaces one by one to establish a management list and a ledger. Except for the objective conditions such as production technology and the need to use coal as fuel, the end of 2018, the city's coal-fired industrial furnaces will be fully replaced or eliminated by the end of the year, Gaoyou City, Yizheng City, Baoying County completed 50 More than %, the remaining coal-fired industrial furnaces were completed before the end of 2019. Where there are reports of leaking reports to coal-fired industrial furnaces, it is not a clean energy alternative task or fraudulent area, and is strictly accountable.

3. Carry out special rectification of coal-fired grain drying furnace. Formulate and implement the “Special Remediation Plan for Coal-fired Grain Drying Furnace in Yangzhou City”, organize a comprehensive investigation and registration of the city's coal-fired grain drying furnace, and establish a management list and a ledger. Before the end of 2018, the city's coal-fired grain drying furnace will be fully replaced or eliminated by the end of the year. Gaoyou City, Yizheng City and Baoying County will complete more than 50%, and the remaining coal-fired grain drying furnaces will be completed before the end of 2019. Where there is a report that the coal-fired grain drying oven is not reported, it is not a clean energy alternative task or a fraudulent area, and it is strictly accountable.

4. Further expand the elimination scope of small coal-fired boilers. Completely replace and replace 35 steam tons/hour and below coal-fired boilers, and strive to replace or eliminate 7 coal-fired boilers such as Jiangsu Yangtai Zhongtian Pipe Pile Co., Ltd. before the end of October 2018, and the remaining coal-fired boilers 2019 10 Completed before the end of the month.
