Get to know about coal to electricity

Research shows that there are six major sources of PM2.5 in Beijing, namely soil dust, coal combustion, biomass combustion, automobile exhaust and waste incineration, industrial pollution and secondary inorganic aerosols, of which about 18% of coal is burned. Coal-burning pollution has a huge impact on the formation of hazy weather. In order to reduce winter coal pollution and improve air quality, many cities in the north of our country started to promote a series of policy subsidies for coal-to-electricity, which are also released accordingly.

On February 17, 2016, the General Office of the Beijing Municipal People's Government issued the "Work Plan for Major Work Division of Work Report of the Municipal Government in 2016", which has perfected the implementation mechanism of responsibility for prevention and control of air pollution.

The report pointed out that in order to save energy consumption and reduce the cost of residents, in principle, the district is strictly prohibited the use of "direct thermal" electric heating equipment (if used, to ensure that residents can not because of the high cost of electricity and re-use of coal); encourage the use of "Multi-energy linkage, multi-heat complex, multi-source integration" and other equipment integration of low-temperature air source, ground source heat pump, solar energy and other auxiliary energy systems. District promotion of heat pumps and "multi-energy linkage" category of equipment should not be less than 80% of the area heating equipment.

To encourage coal-fired boilers clean energy reform, Beijing Municipal Bureau of Finance, Municipal Environmental Protection Bureau raised the subsidy standards. In 2002, 20,000 tons of steam coal-fired boilers were subsidized 55,000 yuan per steam tonne and 100,000 yuan per tonne of steam coal was more than 20 yuan per tonne. On this basis, the intensity of subsidies for coal-fired boilers in suburban districts was further increased Unified increase to 130,000 yuan per ton of steam. On the other hand, the Municipal Development and Reform Commission promulgated a policy to expand the range of fixed asset support for the clean energy reform of coal-fired boilers. Subsidy funds were allocated to 30% or more of the investment in 20-ton steam coal-fired boilers in accordance with the original scale. These policies and measures have effectively promoted the implementation of the task of "coal to gas" in coal-fired boilers.
