Boiler blowdown: First, the function and purpose of the projects of cob fuel boilers blowdown is the object of the sewage drain pan high salt concentration water, boiler water and corrosion and precipitate the salt content in boiler water is maintained within a prescribed range, to reduce the expansion of the pot and the water bubble layer, thereby reducing the salt content and humidity of steam to ensure good quality of steam. At the same time, the sewage may eliminate or mitigate fouling in the evaporator by the surface of the pipe. Second, the ways in which the boiler blowdown Boiler Blowdown points on a regular basis sewage and continuous blowdown two kinds. Continuous blowdown: also called surface discharge is continuously draw off a portion of the boiler water, the purpose is to let go of the salt was dissolved in water and the pan pot water surface float. Regular Drainage: emission time per predetermined time, the main purpose is to let go of the precipitated water boiler slag, of course, with a pan of water soluble salt. Its emissions group should be more precipitation the lowest part of the boiler slag. Third, why the installation of boiler blowdown boiler blowdown water introduced into the larger container expansion down, the vessel is called blowdown. With different ways, it can be divided into two kinds of a given row and even row. Platoon for working medium and heat recovery. Because a given row of sewage water and sewage indefinite periods of time, now we can not be recovered. Given row down by expansion, an upper steam into the atmosphere, the water from the lower into the trench, it is to reduce noise and ensure safety.
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.
In Apr 2014, there was a set 75 ton biomass fired steam projects of cob fuel boilers to Manila, Philippines, and until now, the boiler is working well in power station.
Gas projects of cob fuel boilers is conveyed to the fuel pipe only need to build, without increasing the fuel storage facility, prior to feeding the fuel combustion process and without preparation device, the system is greatly simplified.
