boilers heat recovery waste heat specialty mcrae
It is reported that in March 28, the Office of the ecological environment in Gansu Province on environmental governance ecology, held a press conference. Will be mentioned in: 2019, Gansu Province will improve air quality for the goal, to strengthen air pollution control work. 2019 air pollution prevention and control measures are: to adjust the energy structure, clean winter heating in an orderly way, and then completed more than 400,000 rural residents warm Tukang years Tuzao, small stove coal to gas, coal to electricity or clean coal replacement project; built a sound 86 counties (cities, districts) focused on coal distribution system, formulate issued "the province's reservoirs (for sale) coal yard special clean-up remediation work plan" to carry out the coal market, coal quality control special inspection inspection, serious investigated sales of low quality coal, coal yard dirty and messy and other issues.
1, adjusting the industrial structure, the implementation of "scattered pollution" enterprise remediation special action, complete ban before the end of the relocation, renovation work; continue to promote urban built-up area of heavily polluting enterprises relocation, renovation or off exit, according to the law to promote backward production capacity in accordance with regulations can quit, support and foster a number of competitive energy-saving and environmental protection enterprises.
2, accelerate the implementation of the transformation of ultra-low emissions of thermal power, steel and other key industries, before the end of the year plans to complete within 10 coal-fired thermal power ultra-low emission renovation (except long discontinued); implementation of key enterprise organized, unorganized emission control standards by the end of before the completion of discharge standards smelting production company boiler.
Common technical transformation of coal-fired boilers heat recovery waste heat specialty mcraes What? In order to promote energy saving process, national and regional governments have launched a lot of coal-fired boiler policies, hoping to speed up the progress of the transformation of enterprises to use coal-fired boilers, the technological transformation through various soft sister boiler can achieve more energy-efficient, more environmentally friendly purpose. So what are the more common technical transformation of coal-fired boilers have it? Here's an overview of the transformation of high-quality coal-fired boilers for everyone. 1, coal-fired boiler auxiliary blowers and energy-saving technologies induced draft fan energy consumption and thermal efficiency of coal-fired boiler operation parameters directly related, appropriate conversion technology can be used for coal-fired boiler, the boiler load in accordance with the transformation requires adjusting drum, the air volume to maintain optimum conditions of operation of the boiler, the boiler can save not only coal, but also reduce the power consumption of the fan, so that to achieve a better energy-saving effect. 2, the transformation of coal fired boiler technology devices are currently grate-fired boilers burning coal, which accounts for the majority of coal-fired boilers in the coal boiler will hinder into the wind, affecting the combustion. When the coal-fired boiler coal bucket coal transformation component layer, using gravity filters to block coal, coal bottom-end loosely distributed on the grate, the air inlet beneficial, to improve combustion, improve coal combustion rate, reduce ash carbon content. 3, combustion coal-fired boilers by the transformation technique of this technique coal-fired boilers, pulverized coal amount to be injected into the furnace in place, so that the combustion grate base layer, an appropriate amount of suspension firing increases, must be obtained the saving rate.
Boilers are widely used, and there are some unique problems in China. Although imported boilers heat recovery waste heat specialty mcraes are used in some plants, the pipeline is still carbon steel, oxygen corrosion and CO2 corrosion are serious, resulting in the problem of iron ions in condensate water exceeding the standard is very common. High content of iron ion water is an unsafe factor in boiler, which causes pit erosion and pitting corrosion of boiler wall, and causes boiler perforation to be scrapped.
Not on the bottom of the water (2) Gas boilers heat recovery waste heat specialty mcrae ground surface to prevent moisture corrosion. 2, gas boiler run every 2-3 weeks, should be checked once. 3, gas boiler run every 3-6 months after the shutdown should conduct a comprehensive inspection.
