0 3 MW water boiler
Boiler operator level instructions and material consumption analysis: Boilers, I believe we will not feel strange, because the site has been conducting its study and work, namely to explain the content of the relevant knowledge, so that we have to learn content, Furthermore, to make their own progress and development, so, it can continue well into this product, and at the same time, have a good effect. So, based on this, then, will continue this topic, the specific contents are as follows. 1. boiler, its steel supplies usage, whether related to the boiler type? Boiler, its consumption of steel, from a professional point of view, between the boiler and the type, is not so much because it is not one of the factors, therefore, will have this conclusion. Moreover, based on this conclusion, it is difficult to say, standing modular boiler, its steel consumption than the larger.
Now we look together, when the hot 0 3 mw water boiler outage and restart the practices it!
1, the heating boiler is stopped, as is normal shutdown pressure fire, the blower should outage, then outage induced draft fan, the coal supply is stopped, but not circulating pump outage. Because the water pump outage may cause water vaporization furnace, water pumps still continue to operate. When the system temperature dropped to below 50-60 ℃, and then stop the circulating pump. The intermittent heating may not be necessarily shorter interval outage circulating pump.
2, when the furnace start again, should open the circulating pump, the water in the system has reached normal cycle, open the induced draft fan, blower, start the grate and the coal system, gradually recovered coal combustion. When the shutdown longer required pressure furnace, combustion should preferably seam, after clearing slag, then covered with a thick coal seam fire pressure.
To speed up solving air pollution prevention and control Liaoyang key and difficult issues, Liaoyang city government combined with the actual circumstances of the sky to win the Battle of implementation. Details are as follows.
1, promote clean heating. To proceed from reality, should the electric power, gas should the gas, the coal should be coal, should be hot is hot, warm winter to ensure the safety of the masses. In strict accordance with the "Notice on
2, control total coal consumption. According to energy-saving emission reduction Work Leading Group Office of the City "on the issuance of Liaoyang control total coal consumption program of work (2018-2020 years)" (City of Liaoning Office Savings Fa  No. 3), the city's total coal consumption do control. Vigorously for shutting down energy consumption, safety, environmental protection and other 300,000 kilowatts coal-fired units of non-compliance, capacity indicators for shutting down the unit, allowing the transaction or replacement, can co-ordinate arrangements for building the capacity of ultra-low emission coal-fired units. In 2020, the city's coal accounts for the proportion of total energy consumption control to 58.6% or less.
3, in-depth implementation of coal-fired boiler control. Increase the small coal-fired boilers (including coal-fired boilers and furnaces tea, operating the stove, grain storage and drying equipment, coal-fired facilities) elimination efforts. According to the principle of small demolition and Japan to promote clean energy use, developing the approach to co-ordinate the establishment and management of inventory ledger. Strengthen ecological environment, housing and urban construction, industry and information technology, market regulators linkage, strictly control new coal-fired boilers. 2018, 10 steam tons / hour (or 7 MW) coal-fired boilers and focus on the completion of the phase-out of county level and above all the urban area and old inefficient coal-fired boilers small tasks within the industrial park, small demolition boiler mission of 111; 2019, to phase out coal-fired boilers to further improve standards, expand the scope to promote the elimination of urban built-up area of 20 steam tons / hour (or 14 MW) and coal-fired boilers, in addition to special planning according to urban heating heating boilers other than essential to retain, urban built-up area 20 steam tons / hour (or 14 MW) coal-fired boilers to be eliminated and all.
4, the development of industrial furnaces governance special action. Development of industrial furnace remediation plan to carry out an intensive investigation, the establishment of various types of industrial furnaces inventory management. Increase the non-compliance of industrial furnaces out of efforts to speed up the elimination of small and medium gas furnace. Encourage industrial furnaces use electricity, natural gas and other clean energy or heat from the surrounding power plant. Key areas banned fired stove, the coal-fired cogeneration substantially eliminated heating pipe network coverage heated oven (furnace); out hearth diameter of 3 meters fuels gas furnace, a fixed bed to increase fertilizer industry intermittent coal gasifier reform efforts; focus on the use of gas furnace industrial park, they will not have to switch to natural conditions, should build a unified clean coal gas central principle; prohibition blended with high-sulfur petroleum coke. The industrial furnace governance as key tasks of environmental inspectors, who have not included in the list of industrial furnaces were included in the autumn-winter peak load shifting production program.
The monthly depreciation rate of 10 ton / hr of the gas hot 0 3 mw water boiler = ÷ 9.5% 12 = 0.79%.
The monthly depreciation 10 tons / hour gas hot water boiler = 0.79% * 500,000 = 3950 yuan.
