Heilongjiang: Three years of special rectification and concentrated efforts to tackle scattered coal pollution

　　The reporter learned from the Heilongjiang Provincial Department of Ecology and Environment that Heilongjiang Province has formulated an action plan for tackling bulk coal pollution. It took three years to focus on Harbin City, Suihua City, Zhaozhou County, Zhaoyuan County, Yabuli Ski Resort, The control of scattered coal pollution in key areas such as Xuexiang tourist attractions has effectively improved the environmental air quality of the province.

　　Harbin City completed the demolition and reconstruction of 17,000 households in 14 urban villages, reduced 51,000 tons of loose coal, and completed clean energy and clean fuel replacement in 34 urban villages. At the same time, accelerate the promotion of the pollution control of scattered coal in the urban-rural fringe area and the control of scattered coal pollution in merchants, and the province will reduce 233,400 tons of scattered coal in shanty towns.

　　In rural areas, the implementation of "stalks to replace coal" and "briquettes to replace coal", rural retail households can use the single-family heating technology model of "straw briquette fuel + household biomass stoves"; upstairs farmers, government agencies and institutions can use "straw Two types of central heating technology modes: briquette fuel + biomass briquette fuel boiler" and "straw direct-fired boiler". Build a straw briquetting station to ensure the fuel supply for straw briquetting and increase the amount of straw used for clean heating in rural areas.

　　The province basically eliminates coal-fired boilers of 10 tons per hour or less in county-level urban built-up areas, reduces 328,600 tons of loose coal, eliminates coal-fired boilers from 10 to 35 tons, and promotes coal-fired boilers from 35 to 65 tons. upgrade.

　　The province has completed the ultra-low emission transformation of 73 coal-fired power generating units, and promoted the implementation of ultra-low emission of coal-fired power units that have achieved ultra-low emissions by power groups. Optimize the "near-zero emission" energy layout, and the province has initially planned 3.7 million kilowatts of wind power and photovoltaic power generation projects, including 1.65 million kilowatts in key areas.

　　To implement clean heating steadily, adhere to the “reform by gas”, and encourage parks and enterprises with stable demand for cooling, heating and electricity to develop distributed natural gas heating. The province has added 2.33 million kilowatts of biomass combined heat and power installed capacity, and completed the energy-saving renovation of 40 million square meters of existing residential buildings. Renovate the old heating pipe network of 6000 kilometers, and increase the central heating area of ​​more than 50 million square meters in the province.
