best gas fired steam boiler for central heating
Fire boiler design pitch is much: a room, boiler production plant belongs to class D, to a best fired steam boiler for central heating rated evaporation 4t / h, when the rated output is greater than 2.8MW hot water boiler, the boiler room building fire resistance rating of not less than two ; rated evaporation steam boiler is less than or equal to 4t / h, when the hot water boiler is equal to or less than the rated output 2.8MW, between the boiler building fire resistance rating of not less than three; m-inter-tank, oil pump and the oil heater are inter production plant belonging to class C, not less than two of its construction fire rating, between said room is arranged within the auxiliary boiler room, a room should be set apart from other firewall; March and gas regulator production plant belonging to Group A, which building fire rating of not less than two, should be provided between the boiler room and the immediate neighborhood regulator firewall spaced boiler room, which doors should open outwards and should not directly access to the boiler room, the ground should not be spark Ping.
Matters needing attention in loading and installation of Gas-fired Steam Boiler
Gas-fired steam boilers are a very wide range of special equipment, usually built in boiler rooms. However, in the process of loading and installation, some problems must be paid attention to, otherwise it may cause a certain degree of economic loss.
1. Pay attention to the following matters during the loading and unloading and handling of gas-fired boilers: the lifting capacity of the lifting equipment should match the weight of the lifting boiler. The lifting lug on the boiler with the lifting lugs that cannot be used for lifting can not be used for lifting. The length of the steel cord should be reasonably selected to avoid the scratching of the furnace due to the improper length of the steel cord. The boiler must be protected from any damage during handling and handling.
2. Reserves for maintenance space When installing boilers, ensure that there is sufficient maintenance space around the boiler.
3. Setting and precautions for the base and base of the gas steam boiler The boiler body must be installed on the basis of 100-150mm above the floor of the boiler room. It must be confirmed with the technical personnel of the boiler manufacturing company in advance and constructed according to the basic drawings. The anchor bolts must be reserved on the foundation. The foundation shall be capable of withstanding the maximum weight of the boiler and the amount of water it holds. When installing the base, you must first position it. After positioning, adjust to the same length of the two diagonals of the base, and then tighten all the fixing bolts. The installation of the base is carried out with reference to the reference line.
4, general precautions Be careful not to tilt and impact the boiler and accessories too much. No combustibles can be placed around the boiler. Do not use oil and water to smother the boiler. The boiler should normally be installed in a separate boiler room. The new gas-fired boiler room should not be connected to the house. The boiler room shall not be connected to Class A, Class B and Category C fire hazard rooms using flammable liquids. If connected to other production plants, the application firewall is separated.
For the continuous improvement of the province's environmental air quality, enhance people's happiness index, Henan Province Government Office issued the "2019 campaign of air pollution control implementation plan." Details are as follows.
1, to carry out special treatment industrial furnaces
Based on the melting furnace, the melting furnace, sintering machine (furnace), roasting furnace, a heating furnace, heat treatment furnace, a drying furnace (kiln), coke oven gas furnace 9 categories, to carry out an intensive investigation, the establishment of industrial furnaces Details inventory management, enhance the implementation of classification regulation. Not included in the investigation of industrial furnaces list, all included in the autumn and winter peak load shifting discontinued inventory.
2, to carry out clean alternative
Of coal, petroleum coke, residual oil, heavy oil as the fuel of a heating furnace, heat treatment furnace, a drying furnace (kiln), and actively promote the use of natural gas, electricity and other clean energy and the use of plant waste heat, heating power plant and the like instead.
3, to carry out comprehensive improvement of industrial boilers
Before the end of October 2019, in addition to undertaking tasks and will not have the alternative livelihood conditions, the province's basic complete 35 steam tons / hour boiler clean energy transformation or removal of coal-fired. Transformation methods include the removal, an alternative central heating, gas coal, coal to electricity, use geothermal, wind, solar, biomass with a bag filter. Chaigai on schedule to complete the coal-fired boilers, based on 40,000 yuan / tons of steam prize money up. Forbidden to use has been shut down and eliminate waste coal-fired boilers to cash rewards and subsidies.
4, strengthen upgrading gas-fired boiler
Before the end of October 2019, the provincial municipality and county (city) district built more than 4 tons of steam and low nitrogen gas boiler complete transformation after transformation, soot, sulfur dioxide, nitrogen oxide emissions are not higher than the concentration of 5,10,50 mg / cubic meter.
5, strengthen upgrading oil-fired boiler
Before the end of October 2019, the provincial municipality and county (city) district built more than 4 tons of steam and fuel (including alcohol-based fuel) boiler low nitrogen complete transformation after transformation, soot, sulfur dioxide, nitrogen oxides emission concentration is not high in 10,20,80 mg / cubic meter.
6, vigorously promote urban central heating
Full use of existing resources and central heating facilities, the existing large-scale heat sources and central heating pipe network in the area, in-depth investigation heating demand, and promote the rich heating capacity extends to reasonable radius and root out the potential heating, heating reduce blind spots. Before the end of October 2019, Zhengzhou, Anyang, Jiaozuo, Puyang City, built-up area of central heating penetration reached more than 90 percent, Xinxiang City, central heating penetration reached more than 85%; Luoyang, Xuchang, Jiyuan City, central heating penetration reached 3 more than 80%; Sanmenxia central heating penetration 75% or more; unsealing, Pingdingshan, Hebi, 4 Zhumadian City, central heating rate of 70%; Luohe, Shangqiu, Nanyang 3 City central heating penetration reached 60% .
6 tons of chemical technology chemical parameters of natural gas best fired steam boiler for central heatings 6 tons of natural gas steam boiler technical parameters? Nowadays, people's food, clothing and housing are inseparable from the so-called chemical products. Chemical and chemical industry can be referred to as chemical, petroleum, pharmaceuticals, agriculture and so a place in the chemical industry. As chemical products processing, and various chemical plants, although there will be differences in the production process, but they can not leave some processing all the necessary equipment, steam boilers and other production. 6 tons WNS gas steam boiler, chemical production fast boiler dedicated premix combustion boiler technology, wings tubes, of FGR other new technology to increase the thermal efficiency of the boiler. Manufacturers increase production capacity. 6 tons of gas steam boiler technical parameters are as follows: Model Rated evaporation (6t / h) rated steam pressure (1.6.MPa) WNS6-1.6Y (Q) of natural gas, light oil and heavy oil fast filling. Of course, six tons of gas steam boiler is representative of WNS boiler, three times the structure, energy-efficient gas boiler. Six tons of steam boiler is mainly used in small-scale production and use is very diverse. Class 6 t good gas-fired boiler structure, take up less space, and a low one-time investment, high thermal efficiency.
