Recently, Guizhou Province to combat air pollution, protecting and improving the quality of atmospheric environment, the protection of public health, promote the construction of ecological civilization, and promote comprehensive, coordinated and sustainable economic and social development, in accordance with the provisions of "People's Republic of China Air Pollution Prevention Law" and relevant laws and regulations of atmospheric pollution prevention and control regulations to be amended.
Article XVI: prohibits a planned urban area built or expanded cement, coal chemical, coal-fired thermal power, coking, metallurgy, ceramics and other serious air pollution industrial projects.
Article 24: Prohibition by waste-water treatment, tampering or falsification of monitoring data, in order to avoid on-site inspection for the purpose of the temporary shutdown, open the emergency discharge channel non-emergency situations, abnormal operation of pollution control facilities and other atmospheric discharge atmospheric way to avoid regulation contaminants.
Article 39: It should be the overall planning of urban construction, coal-fired heating in the region, promoting cogeneration and district heating. In the central heating pipe network coverage area, a ban on new or expanded scattered coal-fired heating boilers have been built coal-fired heating boilers can not discharge standards, should be demolished within the prescribed period the city government.
Shall manufacture, import, sale and use do not meet environmental standards or requirements of the boiler.
41: partial restriction sulfur, high ash coal mining, mining prohibition radioactive and arsenic and other toxic substances than standard coal. New coal mines must simultaneously supporting the construction of coal washing facilities. Have been built coal mines, it should be in accordance with national requirements, supporting the deadline for the completion of the coal washing facilities.
Prohibit the import, sale and burning of coal does not meet quality standards, to encourage high-quality coal burning.
Prohibit the import, sale and burning does not meet the quality standards of petroleum coke.
There are hot water boiler fuel gas hot water boiler and hot water boiler, when they appear Priming: 80 t h presure 45 bar steam boiler evaporation surface, the water rises together, produce a lot of foam and the phenomenon of fluctuating; boiler event will Priming with water, steam, steam quality decrease, causing overheating structure vibration and water hammer, impact damage to the superheater and safety equipment operation.
Repair and Maintenance Troubleshooting In order to avoid gas 80 t h presure 45 bar steam boiler steam boiler outlet dust concentration of gas in the course of the maximum allowable dust concentration is higher than the value of scale delineated, dust removal equipment must be set in the rear of the gas steam boiler, the flue gas trapping dust particles and then discharged into the atmosphere. What gas steam boiler common types of dust collector with a gas steam boiler in addition to several common control:? Gas-fired steam boiler gravity settling dust collector, the principle is: when the flue gas into a larger space velocity decreases, larger particles by means of its own gravity dust, separated from the flue gases by natural gravity settling. Cyclone gas steam boiler, known as a centrifugal cyclone precipitator, the principle is strongly rotated in the flue gas dust in a cyclone cylindrical wall gas, and gradually decreased along the tubular wall a helical motion. Because of the strong centrifugal force produced by rotation, the dust thrown cartridge body wall. On the wall surface of soot gradually decreased by gravity to the bottom of the precipitator and discharged through hoppers. Purified flue gas is discharged from the middle of the dust core tube. Gas steam boiler centrifugal mill dust, which is the principle: from the flue gas into a lower portion of the cylindrical housing at a high speed in a tangential direction. Rotation along the cylindrical wall, the nozzle tangential Fangcheng Ping along an upper circumference of the cartridge housing are water, when the water film is formed the inner wall of the cartridge housing, since the centrifugal force, is thrown dust cylindrical wall, and the stick water film and a conical water film flows along the hopper, the mouth is discharged from the ash, flue gas from the upper portion of the housing purifying exhaust.
Steam boiler heating stove manufacturers generally have few work process? Steam boiler heating stove manufacturers generally have few work process? 1, the fuel combustion process. The fuel injected into the furnace through the burner, with air mixture entering the furnace to form a combustible mixture, when it reaches the ignition temperature of the fuel, ignition combustion starts and continues until the fuel is exhausted. 2, of flame and smoke, mainly by radiation heat transfer process to transfer the process manner of water in the furnace, convection mainly in an external surface of the metal is heated, the internal heating surface of the metal mainly conducting manner get on. 3, heated water is vaporized and the water cycle process comprises steam-water separating process.Free Chat
