In mid-April, Hohhot, Inner Mongolia issued a notice (hereinafter referred to as the "Program"), "Hohhot tackling air pollution control plan" (2018-2020), the "plan" to win tough fight pollution prevention, to promote air pollution control, as the city to create a pleasant living environment for the development of the measures.
For air pollution control, "plan" set goals. As of 2020, Hohhot air quality more than two days ratio reached 83.8%, fine particles (of PM2.5) concentration of 35 micrograms / cubic meter. Wherein, 2018 Hohhot air quality objectives: good percentage of days to reach 79.5%, fine particles (of PM2.5) concentration of 39.2 micrograms / cubic meter.
Since 2017 to enter the heating season, Hohhot is the air quality continues to improve, has introduced the autumn and winter air pollution in Hohhot comprehensive reform program "," Hohhot 2017--2018 autumn and winter special inspection of comprehensive air pollution control program of work of law enforcement. " "Hohhot 2017--2018 autumn and winter air pollution in the comprehensive management of supervision and inspection plan", "Hohhot environmental Protection Agency checks on the issuance of the work program of the winter heating enterprises notification", "Hohhot City people's government on the issuance of residential heating clean alternative , "and other series of notifications. Key measures to coal-fired boilers for heating and bulk coal governance.
Second, the city's coal-fired boiler coal yard, residue field to achieve full closure transformation; more than 20 tons of steam / h coal-fired boilers have been installed pollution-line monitoring equipment, and networking with the Municipal Environmental Protection Bureau, established a 24-hour monitoring system.
Through the above measures, Hohhot air quality improved significantly compared to the same period. January 1, 2018 --3 17, good days Hohhot total 66 days, an increase of 4 days last year. Sulfur dioxide concentrations decreased 40.7% over last year, PM2.5 concentration decreased by 20% over the same period last year.
According to (2018-2020) spiritual requirements "Hohhot tackling air pollution control plan", 2018, the Board will eliminate 35 tons of steam utility / h coal-fired boiler room 11 - 15, involves heating an area of 3.872 million square meters. Currently the demolition and integration of clean energy and the transformation is complete, out of the task have been put in place, we have been completed out of eight coal-fired boilers and boiler room of the grid work, removal of nine coal-fired boilers (grid yet dismantled three, to electricity yet dismantled three), and has been able to "break two three clear", the remaining boilers will be completed by the end eliminated.
Cane bagasse fired steam biomass boiler agent burn rice husks and saw dust for sale is a kind of biomass fired steam boiler which mainly takes biomass energy as its fuels, and it includes wood and wood wastes; agricultural wastes and crops produced for use as bio fuels; bio-derived fuels, including municipal solid waste, refuse-derived fuel, sewage sludge, animal waste and so on. Cane bagasse is the waste of sugar cane, in sugar mill, the cane bagasse can be used circularly and cane bagasse fired steam boiler is not only energy-saving but also environmentally friendly, therefore, cane bagasse fired steam boiler is becoming more and more popular around the world. Thailand is the fourth largest country of sugar cane production after Brazil, India and India, and it can supply enough cane bagasse for the cane bagasse fired steam boiler to meet the production demand in sugar mill.
