double drum chain grate boiler structure introduction
Heilongjiang provincial government to respond positively to win the Battle of Blue Sky policy action plan issued by the Ministry of ecology and environmental protection, recently issued "on the issuance of Heilongjiang Province to win the Battle of the sky three-year action plan" (hereinafter referred to as "Plan").
"Plan" requirements, as of 2020, the province of sulfur dioxide, nitrogen oxide emissions are decreased year on year in 2015 to more than 11%; PM2.5 did not meet the concentration level and above cities fell year on year in 2015 to more than 15% , and above the level of urban air quality days ratio reaches 88%, and more heavily polluted year 2015 the number of days decreased the ratio of 15% or more.
"Plan" put forward 47 specific measures from nine aspects, namely: to adjust and optimize the industrial structure, promote the formation of green development; speed up the adjustment of energy structure, build clean energy systems; actively adjust the transport structure, the development of green transportation system; optimal adjustment of land structure, promote urban and rural non-point source pollution control; strengthening regional joint prevention and control, to effectively deal with heavy pollution weather; sound regulations and standards, improve environmental economic policies; for strengthening the infrastructure, strict environmental enforcement inspectors; clear responsibility for implementation of the parties, strict accountability assessment ; strengthen information disclosure, mobilize the whole society to participate.
"Plan" requirements, strictly control the total coal consumption.
1, in accordance with the focus on the use of coal and clean use of principles, focusing on reduction of non-coal for electricity, coal and oil to promote alternative energy by 2020, cities (prefectures) Coal accounts for the proportion of energy consumption fell by 1.5% compared with 2015.
2, bulk coal strengthening control, adjustment and optimization of high-pollution fuel combustion zone ban, the use of high-pollution fuel control, bulk coal alternative strengthening. Clean steadily heating, promoting the use of clean coal and clean energy.
3, to carry out comprehensive improvement of coal-fired boilers, to carry out level and above urban area 10 steam tons / hour coal-fired boilers and "clear" action. Improve energy efficiency, we continue to implement the dual-control operations total energy consumption and intensity.
4, accelerate the development of clean energy, and orderly development of wind power, biomass power generation and actively promote the construction of hydropower development focus on the promotion of river basins, and strengthen the development and utilization of geothermal energy exploration, increase renewable energy consumptive efforts.
Coal-fired industrial double drum chain grate boiler structure introductions need to pay attention to what the transformation of coal-fired industrial boilers need to pay attention to what 1, before removal of the original boiler transformation of the original boiler should be removal of the original main and auxiliary boilers, special demolition work carried out by professionals, so that the whole demolition work done faster to prevent accidents during the removal process. 2, note that the pressure of the boiler, the boiler combustion medium small conversion to gases, but also the original draft combustion into the combustion pressure. In this process, the user needs to pay particular attention to the structure of the whole furnace walls and seal. If the sealing performance is not good, can not withstand the pressure of the boiler, accidents will happen. 3, furnace conversion factor; in many cases the gas burner for the time, because the fuel atomization poor or incomplete combustion furnace gas surplus will be subject to any influence of fire or explosion caused by carelessness, so the transformation is complete should be appropriate where blast doors were installed to prevent the explosion, while increasing the ignition flameout protection device to ensure the safe operation of the boiler; 4, after the transformation test, the need for complex trials to determine the safety after the transformation of high-quality boiler sex. Common method of detection is the pressure after the high-pressure water boiler transformation test. Finally, only after the tests meet the standard, boiler to complete renovation work.
Emissions Time: Continuous Emissions
Blowdown rate: typically 1% or so of the evaporation boiler.
A, by definition, i.e. condensing double drum chain grate boiler structure introduction technology is the use of condensation boilers, the waste heat boiler flue gas back again discharged through the condensing means, make full use of the sensible heat in the exhaust gas and condensation of water vapor to form part of the latent heat released drops to increasing the purpose of the thermal efficiency of the boiler.
