Recently, Xi'an, Shaanxi Province take minus coal, train control, dust suppression, government sources, prohibiting other measures, the air pollution caused by human factors reduced to very low, efforts to improve air quality in Xi'an winter. As of early November, Xi'an has cut 100 million tons of coal-fired, 15 high-ranked companies relocate or shut down.

In 2018, the Shaanxi provincial government issued a formal mandate to inform, Xi'an total of 140 million tons of coal to reduce the task, mainly around the Xi'an city government to cut electricity, central heating boilers Chaigai, urban and rural residents scattered coal and gas supply security in four areas of governance to carry out jobs. As of the end of October this year, has cut coal 1.015 million tons, completed 70.7% year plan. Built area of ​​29,419 catering units are the use of clean energy, outside built-up area 5196 catering units are to switch to clean energy.

Vehicle exhaust is one of the sources of atmospheric pollution. In order to strictly control the "black tail", environmental management staff at the three-ring along the line, passenger stations, farmers market, food stores and other black smoke high incidence of vehicle checkpoints set up 423-bit, low-speed vehicles investigated a total of 71,300 cases to go cut the line , black smoke car 7027 cases.

In the "anti-summer period", Xi'an continue to implement the motor vehicle limit line of control measures, and completed the 3255 update of pure electric buses put into operation, the completion rate of 102%. Newly started construction of public parking spaces 12,908, 86.1% completion rate. Investigate ChaoBiaoChe 3504.

In terms of the source rule, Xi'an cumulative Mopai "scattered dirt" Enterprise 21021 (including New West Ham), complete renovation 8163, completion rate of 38.8%; 15 high energy consumption, high emission enterprises to complete the relocation or shut down; 3399 Taiwan low nitrogen gas boiler to complete the transformation, the completion rate of 99.4%.

40 industrial enterprises complete control of volatile organic compounds, the completion rate was 88.9%; 26 224 restaurants and stalls point to install smoke purification facilities; 1259 spray paint auto repair business to complete in-depth treatment of exhaust gas, and all the installation of pollution control equipment independent meter; the Third Ring Road 336 gas stations outside the full completion of the transformation of tertiary recovery of oil and gas, and all the installation of pollution control facilities separate meter.

In terms of prohibiting, Xi'an completed summer crop straw comprehensive utilization area of ​​249.82 acres of mechanization, comprehensive utilization rate of 95.4%, exceeding the target task. At the same time, organized and implemented six acres and nine provincial and municipal straw utilization demonstration projects, compared with the provincial target increase of 12.5 percentage points; investigate and deal with the problem of black smoke burning from 457; 8 consecutive years of summer and autumn straw Jinshao to achieve "zero fire point" goal.

This year, the Xi'an handled a number of prominent air pollution problems. City of iron-fisted rule examination revealed a total haze to do all kinds of air pollution problems 1862, the city set up a team of 153 people to strengthen the supervision and inspection found problems common enterprise 6128, cross-check inspection found a total of 11,781 business problems. These issues are issued under the supervision of the list of issues to be reform.

Behind the low nitrogen parameters of automatic type boiler explore three popular reason is to promote the boiler heat source energy economy of power, to bring convenience to people's lives at the same time, boiler emissions also increased air pollution. Low nitrogen boiler its high thermal efficiency, the obvious advantages of ultra-low nitrogen emissions, to get people's favorite. Low nitrogen boiler reason to get popular and widely used, is inseparable from the following three reasons. 1, strong environmental protection according to environmental requirements, the country's industrial vigorously implement the project boiler clean energy transformation of small coal-fired boilers to be changed to "oil, gas or electric boilers" and other new energy device. Especially in recent years in Beijing, Tianjin and the Northwest Regional haze serious, and therefore improve the national environmental emissions requirements for industrial boilers. Beijing, Zhengzhou, Xi'an and other places have implemented the most stringent in the history of NOx emission standards (air pollutant emissions shall not exceed 30 mg / cubic meter), to accelerate the marketing process low energy consumption low nitrogen boiler. 2, the combustion more fully and more economical combustion boiler technology to more advanced low-nitrogen, and it is mainly used FGR premix combustion technology, a relatively low index of pollutant emissions, and a more appropriate fuel ratio, the combustion more fully , can significantly reduce the overall energy consumption, and its flame propagation speed is relatively fast, relatively high intensity combustion, heat can be continuously supplied in order. According to the experts explain, low nitrogen boiler requires little worried about the problem of insufficient chemical combustion. 3, high thermal efficiency boiler is an energy conversion equipment, professional production of low-nitrogen boiler as available and high-grade thermal energy necessary for life, for gas boilers, machinery (solid) incomplete combustion heat loss and heat loss is negligible ash physical Excluding. Want to improve the efficiency of the boiler, the boiler only reduce heat loss and heat dissipation reduce exhaust gas temperature. These are fast boiler for your boiler to low nitrogen summary of the popular three main reasons, whether it is national policy or market demand, low nitrogen boiler is an excellent choice. If you have a problem there are other low-nitrogen boiler operation, maintenance and other aspects, can talk to our professional boiler engineers directly by phone or online, we will do our best to help you solve the problem.

The advantages and disadvantages of natural gas and biomass steam parameters of automatic type boiler steam boiler 1, the price of biomass fuels is greatly affected by seasonal. If the biomass supply is the best, the best option is to choose natural gas. 2, gas pipeline need to connect gas-fired, gas-fired gas pipelines can not be used. 3, the storage of the biomass fuel is more cumbersome than natural gas. 4, biomass boilers are not available in all areas, need to be combined with local boiler policies.

A bunch of roots of the impact of vertical steam parameters of automatic type boiler efficiency: basically all over the country are conducting high-profile coal to natural gas movement, vertical steam boiler use, very large cuts infected micro particles, the same time nitrogen oxides and other toxic gases the smoke has also been suppressed. Vertical steam boiler efficiency is a measure of critical standards, common look behind a pile of roots of the impact of vertical steam boiler efficiency. After investigation authorities, vertical steam boiler heat loss is probably due to include these two: undesirable heat loss and flue gas emissions than adequate combustion air. Emission reduction in heat loss can be retrofitted aft vertical steam boiler exhaust heat recirculation installation, or use more advanced types of condensing boiler.
