chinese industry selling China grate for steam boilers
For the 2018-2019 autumn-winter air pollution prevention and control work, Jinhua City, Zhejiang Province issued a public draft, mainly in the autumn and winter to reduce heavy pollution weather Development frequency.
Take measures to reduce coal comprehensive, non-electric focused on reducing the total coal consumption, in 2018 the city's total coal consumption reduction of 1% compared with 2015. New non-owned coal-fired units, the implementation of new large-scale coal-fired units and coal consumption of the same amount of capacity reduction or substitution, elimination of energy consumption, water consumption, environmental protection and safety is not up to 300,000 kilowatts coal-fired units. Development of industrial parks "One District One heat source" action plan, and more than 300,000 kilowatts coal-fired units were heating transformation, promote backward and shutting down small coal-fired thermoelectric integration of coal-fired boilers in the range of 15 km radius of the heat. Optimize the use of natural gas structure, in principle, to new natural gas cogeneration and gas chemical projects, to the new "coal to gas" projects, should adhere to increase coal gas reduction synchronized to gas will change, the premise of the gas supply contract signed and orderly implementation.
Coal-fired boiler (with tea furnace, operating a stove, grain storage and drying equipment, coal-fired facilities) carried out an intensive investigation to ensure that no dead ends, no blind spot. Investigation and the coal-fired boilers to register one by one.
According to the law to increase the city's efforts to phase out coal-fired boilers in accordance with regulations. Before the end of December 2018, the city basically out of 10 tons of steam per hour of coal-fired boiler, built-up areas out of 35 tons of steam per hour coal-fired boilers. Complete 1 set (Yiwu) per hour, 40 tons of steam coal-fired boilers transformation of ultra-low emissions, coal-fired plants to achieve ultra-low emission levels.
In principle, the boiler NOx emission is not higher than 50 mg / m, and comply with appropriate safety boiler specification. New installation and reconstruction of gas-fired simultaneously supporting the low NOx combustion device.
Biomass boilers to carry out a comprehensive investigation, complete control of boiler scale, distribution, fuel, furnace, pollution control facilities and pollutant emissions, and establish a list of management accounting. Yan Gesheng biomass boiler registration, strictly control the new urban area of biomass boilers. Biomass boilers should be dedicated boiler, coal and other prohibited blended with other fuels, efficient dust bags and other ancillary facilities. Actively promote the urban area of biomass boilers ultra-low emissions transformation. For existing biomass boilers, environmental inspection carried out one by one, there are multiple distributed biomass boilers, the implementation of the demolition of small and large industrial agglomeration area.
Fourth, the automatic control system of the type with combined boiler, the system can make the water temperature according to the heating curve operation (error ≤0.5 deg.] C), can be truly "heat demand", greatly reducing heat losses and excessive heat under phenomenon.
How to distinguish pressure hot water boilers and pressure hot water boiler: During hot water boiler used, it was often not clear distinction between pressure hot water boilers and pressure hot water boiler, understand their characteristics, below, small taping we take a closer look. First look at the difference between the two structural constraints, as pressure hot water boiler requires only a reasonable layout of the heating surface, reasonable water cycle, others do not think too much. The pressure hot water boiler under pressure due to their relatively clear, there will be restrictions in all aspects of selecting the location, such as boiler water capacity, it is also one of the two different points. Second, you can look at the issue level control. Pressure hot water boiler level control in question during operation, a drum full of water in the state of opening the box top is still connected, and the pressure is not the same as the hot water boiler. Look inside the boiler pressure changing conditions.
Gas pressure before the boiler needs to pay attention to what is due to the pressurized boiler and pressure vessel having a steam device in operation if not in accordance with safety regulations, accident-prone, and therefore pressure boiler operator must comply with the relevant regulations and procedures implemented . Well run record class work. 1, the appearance inspection and gas pressure in the boiler when the boiler is ready to start pressurization, workers first duty boilers do a thorough examination, including appearance, valves and all joints of the boiler, and then check the pressure of the gas. Ensure that the pressure in the normal range, not too high or too low. Check before opening the supply valve. 2, check the water system pressurized boiler water should be burned, or there will be danger. Front priest dismissed workers should check the water supply system, the pump can be seen, if not normal water discharge valve opens the air, know that you can start the pump, and then turn on the water supply system of each valve. 3, check the water level in the boiler if pressurized water too much or too little can affect the safe operation of the boiler, check the water level is very important before starting the boiler, because the water level gauge function is ready to let the operator know that there is a boiler how much water. boiler. Therefore, before supercharged boiler start, we must look at the position of the water table is normal, but also depends on the water level and water level gauge color table plug is in the open position, in order to avoid the emergence of the phenomenon of false water level, and then see if there is a shortage of water. If you lack water, you can manually complete.
