I. Target: 2020, sulfur dioxide, total nitrogen oxide emissions were reduced over 23.1% in 2015, more than 24.2%; PM2.5 concentration decreased more than 18% in 2015, the ratio of the number of days air quality assessment requirements up to the national , severe pollution and over several days ratio decreased by more than 25% compared with 2015; the full realization of "thirteen five" binding targets.
Second, the continued implementation of the total coal consumption control. By 2020, the city's coal accounts for a further decline in the proportion of total energy consumption; the city's total coal consumption to complete the tasks assigned by the national and provincial; new coal projects to implement the reduction of coal instead.
The development of special programs, shutting down vigorously eliminate environmental protection, energy consumption, safety and other 300,000 kilowatts coal-fired units of non-compliance. For shutting down the unit's capacity, coal consumption and emissions targets, allowed to trade or replacement may be within the total national and provincial construction plan developed according to the control range, co-ordinate arrangements for the construction of ultra-low emission coal-fired capacity unit.
Third, the implementation of the "coal to gas" and "electricity instead of coal." Under the premise of the implementation of the gas source, protect people's livelihood, ceramic, glass, foundry industry to actively promote natural gas instead of coal gasification project, orderly implementation of coal-fired facilities from coal to gas. Combined with regional and industry characteristics can actively promote industrial production, building heating and cooling, transportation, agricultural production, the implementation of the residents living in five major areas "electricity instead of coal", focus on improving the proportion of final energy consumption of electricity accounted for. Of the new "coal to gas" projects, we should adhere to increase coal gas reduction to gas will change under the premise signed gas supply contracts, orderly implementation.
Fourth, to carry out comprehensive improvement of coal-fired boilers, coal-fired boilers to increase efforts to eliminate, consolidate the results of coal-fired boilers eliminated. Coal-fired boiler (with tea furnace, operating a stove, grain storage and drying equipment, coal-fired facilities) carried out an intensive investigation, one by one registration. The city basically eliminated 35 tons of steam per hour of coal-fired boilers and furnaces tea, operating the stove, grain storage and drying equipment, coal-fired facilities, no new 35 tons of steam per hour of coal-fired boilers; 35 tons of steam per hour and coal-fired boiler above (except boilers fired power plant) all meet special requirements emission limits; allowed to remain 65 tons of steam per hour coal-fired boiler and above all the complete energy transformation and ultra-low emissions within the city. County (city) district, zone one by one before the end of June 2019 to develop low-nitrogen combustion rehabilitation programs for existing gas boiler, complete combustion of low nitrogen transformation in this area of existing gas boiler before the end of 2019 more than 50%, before the end of 2020 transformation is substantially complete; after transformation principle NOx emission is not higher than 50 mg / m, and comply with appropriate safety boiler specification. Urban built-up area of ultra-low emission biomass boilers implement reform.
On the whole, lower consumption of coal-fired school water tube boiler for sales, but there are environmental risks, many new coal-fired boilers enterprises are also faced with the situation of environmental transformation or replacement, post huge investment costs.
(3) school water tube boiler for sale can be automatically adjusted according to the thermal load of the boiler during normal operation of the actual output stage operating conditions, automatically when a large demand, reduced demand hour automatic, self-sustained heat balance supply and demand, and greatly reduce the startup boiler the number of shutdowns, when reduced to 30% or less of the rated load, heat production is still greater than the output of the boiler, before proceeding down. (According to relevant statistics, the explosion occurred in the gas boiler start-up and shutdown of these two periods that occurred during ignition and fire in., A small gas boiler gas explosion has occurred 2/3 in the firing process.)[email protected]
