February 20, 2019, the Beijing Municipal Government issued the "Beijing's pollution prevention campaign of 2019 Action Plan" (hereinafter referred to as the "Action Plan"). "Action Plan" clearly 2019 development goals: the first is the city PM2.5年均浓度, three-year moving average concentration strive to continue to decline.
Since 2018 autumn and winter, fog and haze in control efforts continue to increase. Beijing, Tianjin Fenwei Plain, the Yangtze River Delta region of the focus of supervision and maintain a high pressure situation, provinces and cities have also introduced Blue Sky Battle plan, air pollution control sector welcome the opportunity. And because the 2018 autumn and winter abolition of green "one size fits all", so that pollution from the administrative means to switch to environmentally friendly means to speed up environmental protection business orders release.
"Winning Blue Sky Battle three-year action plan" called for increased efforts to eliminate small coal-fired boilers, the county level and above urban area basically eliminated 10 tons of steam per hour and coal-fired boilers, in principle, to the new 35 per hour tons of steam coal-fired boilers. We believe that, under constant fog and haze, the small boiler phase-out process will accelerate. Research believes that by 2021 the transformation of coal-fired central heating investment 88.6 billion yuan, annual operating income of 240 billion yuan, the central heating market will also speed up the release with the environmental supervision.
Professionals expect non-electric air control about 192.2 billion market space, ultra-low emission thermal power market reform space of about 65.7 billion yuan, the whole vast air pollution control requirements.
In addition, the high diesel vehicle emissions, is also one of the main source of haze pollution. Considering the number of ministries had jointly issued by the Ministry of Ecology and environment "diesel truck pollution control tough fight Action Plan" diesel vehicles, boats become the focus of the next step of action to win the Battle of the blue sky.
If the gas fired boiler to boiler, boiler output in case of the same, C02 emissions can be reduced by more than 26%; S02 substantially zero; the NOx emissions by at least 33%; ash and soot are reduced to zero; Green environmental protection effect is remarkable.
3, reasonable program of boiler rehabilitation programs must be simple and easy to do: less investment and quick, short construction period. Accordingly, the content of the boiler according to the transformation in the transformation of the less the better, and can be taken to change only the furnace combustion apparatus, part of the basic structure of the transformation range as not to exceed the boiler body.
4, the reliability of the gas supply when the gas supply is not reliable, the fuel system may be provided. If you need to re-consider leaving room for coal-fired boilers, should select the appropriate way to meet the requirements of gas.
2. Horizontal steam boiler output
The reason food factory boiler companies in sri lanka induced draft fan vibration generated by the induced draft fan vibration analysis of causes of food plant boiler induced draft fan of the analysis is to rely on the input of mechanical energy, increase the gas pressure side by side with mechanical feed gas has important applications in food plant boiler. But abnormal vibration induced draft fan will occur in the daily operation, not only will affect the equipment, but also affect the operation of the whole food plant boiler. Therefore, it is necessary to analyze the abnormal vibration induced draft fan. And to take appropriate and effective measures to do a good job to provide protection for the normal operation of the boiler plant food. Cause induced draft fan vibration analysis food plant boiler 1, via two rolling bearings fulcrum of the rotating rotor of the motor. Axial and radial clearance of the bearing is small, the smallest vibrations caused during cleaning and lubrication hole. Usually does not cause too much impact on the induced draft fan.
