China Rice Husk Boiler For Sale
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.
Emergency shutdown processing steps gas china rice husk boiler for sale boiler will sometimes burst some cases, faced with the handling of the emergency shutdown. Xiao Bian summary of the situation based on past experience and measures to deal with the emergency shutdown of the boiler, to help you understand more fully the boiler. First, when the following conditions requiring emergency shutdown 1, vapor pressure exceeds the allowed safety pressure, stopping for gas taken, strengthen water supply, after the wind reduction measures, the pressure is still rising. 2, boiler water, water tables have not see the water level in the steam drum water level gauge steam valve closed or measures to increase the water supply, the water level is still invisible. 3, boiler filled with water, the water level has risen to the highest level of visibility, turn on the water but still no visible water level appears. 4, all the water table or pressure gauge all does not work properly. 5, all safety valves, sewage valve does not work properly all. 6, the boiler pressure parts, such as a drum, tube, water wall tubes is damaged, or when the personal security device crisis. 7, water supply equipment failure, nor spare. 8, while the furnace wall cracks during collapse danger. 9, delivery, induced draft fan damaged, can not continue to run down. 10 other events a serious threat to the safe operation of the boiler. Second, the emergency shutdown processing step 1, quickly turn off process. First shutdown burner, and close the gas supply valve to stop gas supply, and then cut off the valve, and finally opening the air exhaust valve or safety valve down precipitation. 2, rapid cooling furnace water treatment. After the shutdown can not continue to feed water to the boiler. When there is no water leakage or water, the cooling time can be shortened, accelerated cooling rate, cooling down the sewage water through alternate methods, and maintain the level. When the boiler is severely short of water, the method can not take rapid cooling, water supply to the furnace is prohibited to continue, otherwise there will be risk of explosion occurred. When the boiler is full of water, should be reduced combustion (fire thought into a small fire), open the drain valve turn on the water, while the opening of the trap on the main and sub-cylinder steam pipe to prevent steam away large amounts of water to produce water-flushing . 3, during shutdown, so that the furnace is not cooled too fast, to prevent the flue gas, the pressure receiving member and other member by inflation port being damaged by quenching.
Workflow hot water china rice husk boiler for sale simply look at today's workflow hot water boiler. The simple conclusion that the working process to the main boiler fuel combustion, heat transfer, vaporization and heating of the water with the superheated steam and the like. The entire boiler boiler composed of two parts and auxiliary equipment. Boiler: boiler body is the main part of the boiler equipment, is composed of two parts consisting of pot and stove. Hot water boiler system in a soda boiler, which main task is to receive a fuel suction heat released, the water is heated, evaporated and finally becomes superheated steam having certain parameters. It consists economizer, the drum, the downcomer, the header, water wall, superheater and reheater connecting pipes and other equipment and valves. A hot water boiler economizer: vertically positioned rear of the boiler flue, the use of flue gas waste heat boiler feed water, reducing the exhaust gas temperature, increase boiler efficiency, save fuel. Two hot water boiler drum: at the top of the boiler, is a cylindrical pressure vessel, which is under water, the upper portion of the steam is that it accepts the economizer runoff, while the downcomer, the header, Wall together form water circulation loop. Wall water absorbs heat generated in the soda mixture was collected in the drum, conveyed to the saturated steam superheater after water separation. Three drop tube hot water boiler: the water supply pipe water wall, the effect is the introduction of water into the steam drum to the lower header redistribution respective waterwall tubes. Dispersion in small diameter and the large diameter downcomers Downcomer two kinds. Small diameter pipes of small diameter drops, the water cycle unfavorable. Wall four lower header: the header main role is to bring together quality, or to redistribute the working fluid through the other header by the header pipe. A water wall is thicker lower header tube closed at both ends, its role is connected to the downcomer and the water-cooled wall, so as to function together, mixing, redistribution action of working medium. Five water-cooled wall: at the furnace around its main task is to absorb radiant heat of the oven, to evaporate water, which is the main heating surface modern boilers, while protecting the furnace wall. Six superheater: its role is to drum saturated steam into superheated steam having heated the certain temperature. Seven hot water boiler reheater: its role is done in the steam turbine power section is heated up again, and then continue to work in the steam turbine. These are the hot water boiler workflow profile, I hope for your help.
To get this large-scale equipment running smoothly china rice husk boiler for sale heating efficiency, every component is crucial, because they fit together in order to allow the boiler to achieve a good run. Induced draft fan is the main part of these components, today we have to speak briefly on the boiler equipment, Fan of any use.
