1. Reduce the heat loss of industrial boiler systems for concrete exhaust:
(1) The air leakage rate of the high air preheater, especially the air leakage rate of the rotary air preheater;
Henan gas hot water industrial boiler systems for concrete maintenance method including Henan Henan gas boiler gas water boiler, gas hot water boiler in Henan, Henan gas steam boilers, gas hot water boiler in Henan which include gas heating boilers and gas boilers bath, as the country "West-East Gas lose "project implementation, gas boiler gradually become the people's choice. So what Henan gas hot water boiler maintenance should pay attention to it? First, Henan gas hot water boiler during operation Note: 1, Henan, gas-fired furnace does not allow pressurized combustion or smoke, easy to burn out because stoker hole cover. 2, not on the bottom of the water gas boiler Henan ground surface to prevent moisture corrosion. Second, Henan gas hot water boiler running every 2-3 weeks, should be checked once. Third, Henan gas hot water boiler run every 3-6 months after the shutdown should conduct a comprehensive inspection. (1) on the inside and outside of Henan natural gas hot water boiler inspection, as part of the pressure welds, corroded steel inside and outside the phenomenon, if found should be repaired in a serious flaw, if not serious defects also repairs until the next shutdown , such as found in Henan have gas hot water boiler suspicious, but does not affect safety, records should be made for future reference. (2) Henan gas hot water boiler inspection After completion of the water may be boiler primer coating to prevent corrosion. Fourth, Henan gas boilers and boiler base paint at least once a year. Fifth, Henan gas boiler regular period of time without maintenance: dry and wet two kinds, one month shutdown, maintenance of law should be adopted dry, wet maintenance shutdown method can be used the following month.
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.
Industrial gas boiler service life than the longer, generally 10 - 20 years, but in order to achieve such a long life and good operating results, maintenance and repair process is essential. Among them, water is an important step.Free Chat
