Some of the causes direct impact on the thermal efficiency of horizontal coal fuel 15 ton steam boiler of the country are carrying out a blaze of glory roaring coal to natural gas operations, the choice of horizontal steam boiler, greatly reducing the fine dust contaminated with dust, along with toxic gases such as nitrogen oxides emissions It has also been suppressed. Thermal efficiency is a key measure of horizontal steam boiler, a good start and that is that let you look at some of the causes direct impact on the thermal efficiency of horizontal steam boiler. Through research departments, the heat loss of horizontal steam boiler is very important from two aspects: the combustion air-fuel ratio is not satisfactory and Smoke and heat loss. Smoke and heat loss reduction should be modified in the tail horizontal steam boiler soot waste heat recycling install, or choose would be more leading series condensing boilers. Combustion air-fuel ratio over the substandard Analysis: common horizontal ejector-type steam boiler burner choice, without the formation of air-fuel ratio can be flexibly adjusted. Most of the horizontal steam boiler selected non-automatic strong emission burner, leading to the root causes of unsatisfactory air-fuel ratio has the following areas: air-fuel ratio is not ideal is more important is divided into two kinds of probability: When an excess of oxygen, there will be endless excessive cold air is heat conduction, resulting in increased energy consumption horizontal steam boilers, hot horizontal steam boiler efficiency decreased; when oxygen is not standard, incomplete combustion occurs, generating heat horizontal steam boiler efficiency decreased.
Electric coal fuel 15 ton steam boiler is electrically heated by electrical power installed for the manner of thermal energy, so that the completion of the reaction the boiler, the steam output device outwardly, is a new innovation of "coal to electricity" policy.
The final step is to select which type of coal fuel 15 ton steam boilers currently on the market have the type of fuel boilers, electric boilers. Due to the current state for the "coal to electricity," the advocate, more companies may choose an electric boiler, but there are energy consumption, safety issues such as the traditional electric boiler, by contrast, the crown than conventional electric steam boilers boiler energy saving more than 30% compared to conventional steam boilers have increased security.
Leshan City, Sichuan Province issued a notice "Leshan City to win the Battle of the blue sky plan", the program made specific control measures and methods for the quality of atmospheric environment, as follows.
1, and strictly control the total coal consumption. Timely expansion of high-pollution fuel combustion zone ban scoping, year by year break down total coal consumption reduction targets. In 2020, the city's total coal consumption is not more than 7.075 million tons, accounting for primary energy consumption fell to below 30%. Strict control of new construction, renovation, expansion of coal projects, new coal project implementation year coal consumption reductions times the amount instead. Wutongqiao, multiple Qianwei existing administrative areas with coal-fired boilers, in accordance with the total capacity and operation of the boiler coal consumption reduction principle of substitution, central heating facilities in the new base construction of the park, but it must be stable ultralow emission standards, and to eliminate the heavy pollution weather and atmospheric environmental quality standards as a prerequisite for a stable schedule, bear autumn and winter peak load shifting and eliminate future responsibility.
2, to carry out comprehensive improvement of the boiler. Increased inspection efforts to prevent the resurgence of small coal-fired boilers. The city is not implemented before the air quality compliance and stability, a ban on new or expanded coal-fired boilers. Municipal Economic and Information Technology Bureau, the Municipal Ecological Environment Agency jointly entrust qualified units, the implementation of the transformation of ultra-low emissions, the use of coal industry enterprises to carry out at least once a major air pollutant emissions supervisory monitoring every year. Ban on new fuel boilers and other cogeneration coal, fuel oil. New gas-fired boiler construction simultaneously low NOx combustion facilities, low NOx combustion is completed before the end of December 2019, the transformation of existing gas boiler. City and county built-up areas the implementation of ultra-low emission biomass boilers transformation.
3, bulk coal use to carry out special rectification. Using coal for use in all high-quality coal, coal mines by 2020, all built to retain supporting washing facilities, the city's raw coal rate of 90%. In accordance with the principle of progressive advance of Pingba first, and then the mountains, the "coal to electricity," which, according to local conditions in key areas to promote rural villages, "coal to electricity, coal to natural gas" work. A total ban on the circulation and use of low quality coal, bulk coal investigate unlicensed business activities according to the law, high-pollution fuel combustion zone ban is abolished bulk coal sales outlets, to promote electricity instead of coal, substitution of gas for coal, to promote the use of clean coal, advanced civilian stoves . In 2020, within 30 km surrounding county town and township range of the main city of almost no bulk coal use.
4, accelerate clean energy alternatives. The implementation of "gasification of the city, alternative energy, clean alternative" projects, subsidies to change the electric boiler. 2020 non-fossil fuels in primary energy consumption should increase to more than 38%. Research to develop new energy truck traffic right of way, to encourage policies on sustainable management, new and replacement buses, rental, sanitation, postal services, commuter, logistics and other light vehicles with electric vehicles. By 2020, postal services, urban delivery, light sanitation basic vehicle for the electric car, for the van passes light logistics vehicle essentially electric cars, buses central city using all new energy vehicles and reached the country six emission standards for natural gas clean energy vehicles.
