solid fuel water tube boiler
Causes steam heating boiler supplies explosion which has been steam boilers are security issues can not be ignored, possible causes of boiler explosion of many, simply summarized the following points: 1 Annex failure safety: safety valve does not start; overpressure alarm. failure; low water level alarm malfunction. So, boiler safety accessories must be required to regularly check. 2. The boiler itself is defective: pressure parts when aging, strength weakened, or leakage, corrosion, deformation, scale and other defects, not timely maintenance in order to eliminate hidden dangers, but to sick to run the boiler, and so on. Therefore, the boiler must be regularly tested according to national requirements. 3. poor management, fireman officer is not responsible or low levels, lead to misuse. So fireman must obtain operating permits required. For the actual operation of the boiler, the more these are not the main reason for the explosion. In actual operation, the most common situation is to add cold water after the boiler dry out, which is very dangerous. Most operators also need to guard against. There may be a clogged vent leading to a pressure cooker pot pressure continued to increase, the excess pressure can not be discharged out of the pot to reach the strength to withstand the pressure will naturally explode, of course, does not rule out the pot itself reason, quality tests, pot body has leaked, there are usually not enough to exhaust could cause an explosion. Therefore, before use, carefully check the vent is not smooth, does not violate the instructions for use and contraindications, there will be no danger.
Luzhou, Sichuan issued a notice to win the Battle of Blue Sky embodiment. Program requirements, to promote ultra-low emissions to upgrade the steel and cement industries, and increase efforts to eliminate small coal-fired heating boiler suppliess, phasing out the whole 10 tons / hour and below the coal-fired boilers. Details are as follows.
1, to accelerate the development of clean energy. Scientific and orderly promote clean energy development and utilization of hydropower, natural gas (shale gas), wind power, solar, biomass and so on. By 2020, the city's total primary energy consumption of 12.48 million tons of standard coal, total coal consumption control in less than 6.5 million tons, accounting for the proportion of total energy consumption control in less than 42%, the newly constructed and put into operation a large municipal solid waste incineration power plants, garbage power generation capacity of 12MW, a new wind farm installed capacity of 48MW, the development of distributed PV installed capacity of 5MW, the new large biogas 5. Improve the construction of reservoirs for natural gas production and marketing system.
2, to promote the use of clean coal. Efforts to increase coal washing, coal simultaneous construction of new coal washing facilities, supporting the completion of existing coal mines coal washing facilities in accordance with points Area. Improve coal quality and use of standard industrial, commercial coal do not comply with environmental standards required by regulations of coal quality merchandise. Prohibit the circulation and use of low-grade bulk coal, bulk coal investigated and dealt with according to the law without a license behavior. Increase the civil bulk coal clean governance efforts to promote electricity instead of coal, substitution of gas for coal, to promote the use of clean coal, advanced civilian stoves, strengthen civil bulk coal management. Strengthen regulation and control coal use in autumn and winter.
3, to carry out comprehensive improvement of coal-fired boilers. Increase efforts to eliminate small coal-fired boilers. By 2020, the county level and above cities phasing out the built-up area per hour and 10 tons of steam coal-fired boilers, in principle, to a new 35 tons of steam per hour of coal-fired boilers, in principle, to other parts of the new 10 per hour tons of steam coal-fired boilers. Ambient air quality standards are not areas should further increase efforts to eliminate.
4, increase Condensing units and cogeneration units technological transformation efforts, speed up the heating pipe network construction, fully release and improve the heating capacity, eliminate network and bulk coal fired boilers within the coverage area. In areas not have cogeneration district heating conditions, a plurality of existing coal-fired boilers of small, actively promote the implementation alternative energy.
The NaOH (4kg / m 3) and Na3PO4 (1.5kg / m 3) into the container, with the soft water soluble, and then pumped into the heating boiler supplies furnace from a lower portion of the header. Note that to maintain a homogeneous solution of alkali concentration.
