Run industrial d type boiler water tube 150 psi pitchers areas requiring attention are what run industrial boilers to note what? Mainly industrial boilers to provide heat and power for other industrial production equipment in order to maintain the momentum of its production and operation. One of which is industrial boilers, mainly to maintain the steam-powered electricity generation or supply. Another is the traditional industrial boilers, coal as raw material which, powered by waste heat recovery, to maintain production run, it is widely used in industrial production. 1. Use industrial boiler operators, requires not only the knowledge and skills of skilled operators, the operation of the boiler should be prohibited from leaving their jobs, the boiler in a state of neglect, reduce accidents too much pressure boiler water level or higher The phenomenon. 2. When the boiler pressure increases, the staff should be subject to rigorous technical evaluation of relevant professional departments to be adjusted to avoid overpressure phenomenon mislead operator error without adjustment. Pressure gauge and safety valve common faults, while related to the operation of the operator should be strengthened. Timely processing of boiler operation anomalies. 3. Prior to the use of the boiler, the boiler should be fully checked structure and current and voltage is within the normal range. To avoid unreasonable boiler structure, poor weld quality, safety accessories related failures caused by industrial accidents occurred in the boiler during operation, and should be sufficient for boiler water treatment prior to use to reduce the incidence of accidents in the run and run.
Chain grate stoker boilerbelongs to traditional horizontal boiler type. Feature with mature technology, simple structure, reliable running and easy operation, chain grate stoker boilers are widely used in Pakistan and which accounts for a large proportion among the boiler size of 75t/h coal fired chain grate boilerusing in Auto industry. According to coal quality and working condition requirements, the user can choose clockwise rotation grate type, counter-clockwise rotation grate type, spreader stoker type and other types.
Shanxi Province to continue to improve and protect the environment, prevention of air pollution, with "Environmental Protection Law of People's Republic of China", "People's Republic of China Air Pollution Prevention Law" and other relevant laws, introduced the "Shanxi Atmospheric Pollution Prevention Act" ((hereinafter referred to as " regulations ").
"Regulation" is mentioned, Shanxi coal consumption will implement the total control system, and gradually adjust the energy structure, reduce the proportion of coal in primary energy consumption. Provincial People's Government will work with the energy department in charge of relevant departments, according to the needs of economic development, social and environmental carrying capacity of resources, the development of the region's total coal consumption control target.
First, governments at all levels to limit sulfur points, high ash coal mining. New coal mines should simultaneously supporting the construction of coal washing facilities, so that the coal sulfur content, ash content meet the required standards. Have been built in addition to the mining of coal mine belonging to low-sulfur, low-ash or coal-fired power plants have been in accordance with the requirements of discharge standards do not need washing outside, it should be a deadline for the completion of supporting coal washing facilities. When coal, gangue, coal cinder, coal ash and other materials, should take fire and dust prevention measures to prevent air pollution.
Second, the coal-fired power companies, coking, and other steel companies use coal shall clean production processes, supporting construction dust removal, desulfurization, denitrification device to reduce the generation and emission of atmospheric pollutants.
Third, the city government should promote cogeneration and district heating coal heating in the region. In the central heating pipe network coverage area, prohibit new construction, renovation, expansion scattered coal-fired heating boilers, central heating pipe network coverage prior to the completion of use of scattered coal-fired and coal-fired heating boilers have been built can not discharge standards heating boilers, should be demolished within the prescribed period the city government.
Fourth, the Municipal People's Government shall be divided into districts to improve the quality of atmospheric environment in accordance with requirements, it will be designated urban area to ban coal region, and gradually expand. County (city, district) people's government can scoping ban on coal zone in accordance with the actual situation. Delineation ban on coal zone should consider the needs of life of local residents. In addition to coal coal ban areas, central heating and raw material coal companies, prohibit the storage, distribution and burning of coal and its products.
Fifth, governments at all levels should strengthen the management of civil bulk coal. Prohibit the sale, does not meet the civil standard of quality coal for coal, lignite ban, coal washing, slime and other low-quality coal use low-quality coal as a civilian.
Focus on gas-fired d type boiler water tube 150 psi pitcher piping design gas supply system gas boiler gas pipeline system is reasonable, not only economic but also for investment and operation of gas supply systems also have a significant impact in ensuring safe and reliable operation of gas boiler great relationship. Therefore, it must be given adequate attention in the design. Boiler gas supply system generally supply duct inlet means, gas piping system and a boiler room emission purging conduit and other components. Some requirements are as follows: 1) from the boiler room to the gas pressure regulating stations gas pipeline (gas introduction tube boiler), in addition there are special requirements of production to be considered outside the double tube gas, generally single gas supply tube . When gas double pipe, each pipe capacity by gas boiler 70% of the total gas consumption is calculated. 2) When the intake pressure regulating device at 0.3MPa or more, than the surge and large, large noise may be generated, in order to avoid the noise transmitted along the pipeline to the gas boiler room, the device should have a regulator 10 ~ 15m the section of pipe laid underground to take. 3) gas is introduced from the outside manifold gas boiler room, the total should be installed at the inlet shut-off valve, a gas-flow direction, the valve should be installed before the vent pipe, and a sampling port mounted in the vent pipe should be installed after the purge valve joints. 4) between the gas introducing pipe connected to the boiler supply mains, or can be connected to an end portion of the intermediate connector. When the number of the gas boiler gas boiler room station 4 or more units, each of the gas supply pressure boiler similar tube is preferably used in an indirect manner that the person.
