Boiler also added insulation and mute elements, working noise less than 60 decibels (normal speaking voice), almost no noise pollution affect the environment, so the water tube boiler instrument can be placed in living cells use, will not affect the normal life of the residents, there was no nuisance phenomenon.
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.
What are the characteristics of the gas water tube boiler instrument? Gas boiler basically have some of their own feature is the fuel to burn A boiler gas and invented, of course, such a boiler is relatively economy-oriented, and most of the friends in the selection process which, as an apparatus which will substantially their necessary equipment, from the current situation, when the selected gas boiler, comprising a heating boiler are some gas, or a gas boiler bath, with the gradual upgrading of the national natural gas project, these gas boiler, slowly she became our first choice. 1) Today's gas-fired boiler basically equipped with imported brands are some of the burners with a high degree of automation, and their controllers can basically be purged automatically, with electronic automatic and automatic combustion flame function, and can automatically adjust the ratio, the performance point of view is very safe, has good combustion efficiency, and with a different flame protection device can effectively ensure safe operation. 2) In the process of the present gas boiler use, they have a computer-style controller, all functions are all stored on the chip can be a very intelligent features, and all of a boiler can be key to boot, all automatically to timing, positioning operation in a short time, even before the overall time to complete boiler stop, you do not need to be specially guarded, so you can maximize power savings. 3) a substantially gas boiler are also inserted more flame retardant chips, they are able to effectively slow down the speed of the smoke, and can continue to strengthen the heat exchanger, a relatively low temperature until the entire interior of smoke discharged, it can better save fuel, reduce heat loss.
On the gas water tube boiler instrument, if it is 1 ton of water, then heat the temperature of progress once the demand is 1,000 calories, but this time, can reduce gas consumption. If the natural gas heating value is 8600 kcal, then the above problems can be obtained through the calculation is concluded, each producing 8.6 tons of hot water, it can save the amount of natural gas is of 1 m.
2.10 tons boiler, the amount of natural gas consumed per hour, how much is? Different auxiliary boilers are equipped with the same right?
10 tons of boiler, which is on the calorific value, the equivalent of 6 million kcal. Therefore, if the heat value of natural gas in accordance with the calculation to 8600 kcal, then its consumption of natural gas per hour, is about 700 cubic meters. And on the issue of two, whose answer is NO, that is, different boilers, auxiliary equipment, it is not the same.
