"Green Castle is the gold and silver mines," Mianyang City, Sichuan Province to respond positively to President Xi's philosophy of environmental protection, strengthen the construction of ecological civilization, and vigorously promote the city's air pollution control, focusing on small commercial boilers for sales county level and above cities out of coal, comprehensive enhance the transformation of 20 tons of steam / hour or more coal-fired boilers, let Mianzhou earth, the sky bluer, and more green, the water clearer.
In advance of the phase-out of coal-fired boilers, the city's focus on top-level design, in June this year issued a "county-level and above Mianyang urban area small coal-fired boilers work out program," clearly take demolition, renovation, clean energy alternatives and other measures , before the deadline to the end of March 2019, phasing out the county level and above urban area 10 steam tons / hour and the small coal-fired boilers (because of the promotion of cogeneration of small coal-fired central heating boiler replacement must be before the end of 2020 total phase-out). Not included in the program for the elimination of the objectives and tasks of various types of small coal-fired boilers, find an out of one.
Eliminate small coal-fired boilers for improving urban air quality has a positive effect. In Mianyang, a wine business one step ahead, we tasted the sweetness: switch to phase out coal-fired boiler gas boiler. Before coal-fired boilers, the company must invest a lot of money each year to buy coal used in the treatment of fly ash and slag above, and coal combustion will bring countless pollutants.
After starting gas fired boiler to boiler project, which began to corporate purchase and install a gas boiler, energy-saving cooking pot bottom, ice bucket, multi-cooler tube array, sewage tank 58 and other equipment (sets); and in 2017 December formally put into use. After coal to gas, coal storage area is no longer required, cinder storage area ,, new construction land for the enterprise, greatly reduce production operating costs. "
This year the city built-up area of the city's coal-fired boiler phase-out targets small task is 25 units. City Commission by letter, the Environmental Protection Agency, Bureau of Quality Supervision and other relevant departments to strengthen organizational leadership, establish long-term working mechanism, compaction work responsibilities, in close collaboration to promote the division of labor, and strengthen supervision to ask efficiency, strict examination and approval for the record, put an end to new coal-fired small boiler, strengthen propaganda and guidance, do a solid job of work to promote the service. As of the end of November, this year's phase-out plan included 22 small businesses of 25 coal-fired boilers have completed 24 units, of which the use of special equipment to complete the cancellation of the registration certificate of 17.
City Commission by letter the person in charge, the next step, they will actively cooperate with relevant departments to intensify its efforts to strengthen the county has not yet out of the task of supervision and corporate efforts to accelerate the phase-out of the boiler has been using special equipment write-off registration certificate , guidance throughout the solid performance of the late acceptance procedures, and make due contributions to effectively improve the quality of atmospheric environment in Mianyang.
Burner fuel gas selected selection principles which fuel gas commercial boilers for sale burners should be based on structural features and performance requirements of the boiler body, in conjunction with user conditions, making correct comparison, several general principles according to the following options: 1) according to user selection of used fuel type, liquid fuel kerosene, diesel oil, heavy oil, residual oil and waste oil, fuel gas city gas, natural gas, liquefied petroleum gas and biogas, fuel should have the necessary analysis of data used: ① kerosene, diesel should have heat and density. ② heavy oil, residual oil and the viscosity should, heat, moisture, flash point, mechanical impurities, ash, freezing point, density and the oil temperature. ③ should calorific gas, gas pressure and density. 2) to select the type burner nozzle atomization method or the gas burner and the furnace structure according to the performance of the boiler. 3) the burner output should match the rated output of the boiler, choose a good shape of the flame, such as length and diameter so as to adapt the furnace structure. The required combustion air is supplied from the root flare fuel gas and air or oil mist uniformly mixed rapidly, to ensure complete combustion. The rated output of the boiler and boiler efficiency is determined, the fuel consumption is calculated, and then selected according to power a single burner arranged to determine the number of burners. Increase the number of burners, in favor of the atomization quality assurance wind oil mix, but too many, and not easy to operation and maintenance, will give burner arrangement difficult. 4) adjusting the burner to a large extent, be able to adapt to changes in boiler load, to ensure complete stable combustion under different conditions. 5) fuel atomization less energy consumption, adjusting the wind resistance of the device to be small. 6) Effects of noise and smoke emission must comply with environmental standards, mainly emissions S02, CO and NOx must be lower than the predetermined country, should use low NOx burners and low noise. There are integral and split two 7) a burner assembly embodiment. I.e. monolithic burner body, the burner and a combustion air blower system (including an oil pump, a solenoid valve, a servo motor or the like) into one; split i.e. burner body (comprising a combustion head, oil or gas systems), fans and combustion burner control system (including the control box, fan thermal relay, AC contactor, etc.) are each independent three-part system, according to the specific requirements of the boiler and user choice. Simple 8) should be used in construction, reliable operation, easy to adjust and control the repair, easy to implement automatic control of the combustion process in the burner. 9) to deal with the burner brand, performance, price, and service life of comprehensive comparison. 10) In addition to the burner air pressure to overcome the resistance of the boiler body considered, but also to overcome the resistance and flue gas economizer system.
Why low nitrogen commercial boilers for sales are more popular in the market? In China, coal pollution is getting worse. In many industries, not only the hotel's heating, operation of the plant machinery, as well as the needs of people's lives and so on. In many places we need to use gas burners. Combustion gas released a lot of atmospheric pollutants. According to the data, the impact of coal emissions of atmospheric pollutants on the ecological environment is getting worse, here to introduce you to why the low nitrogen boiler popular? 1, more professional in terms of low nitrogen boilers, conventional boilers cost first general, conventional boilers used in China is a certain proportion of gas and air for combustion are mixed in, so that the mixing temperature of the aerosol generated by the combustion is relatively high, resulting in low efficiency of energy supply. Second, the existing gas boiler has become the main way of the city's small and medium enterprises use boilers. The main cause of ozone exceeded targets is nitrogen oxide from gas boilers and motor vehicle emissions due to the use of conventional boilers burning coal can not be completely full. Finally, the safety of conventional boilers is problematic, flammable and explosive, and at a temperature change of circumstances such as insufficient fuel, can lead to explosion. 2, the most important advantage of the well-known low nitrogen low nitrogen boiler boiler most predominant feature is the external energy saving, a low nitrogen boiler pipes by using a relatively low thermal conductivity of the heat insulating rock wool insulation, thereby reducing heat boiler amount, to achieve energy saving effect. Low NOx combustion technique premix, by improving fuel combustion condition, thereby suppressing the generation of nitrogen oxide, rather than a simple flue gas treatment. 3, in addition to environmental reasons people choose low-nitrogen in addition to environmental protection boiler, boiler advantages in energy saving is also very obvious. Low nitrogen boiler, the use of advanced technology and zero pressure swirl mixing valve technology, the ratio of air and gas is always constant, variable load, the late running costs can be substantial savings. Also reduce the operating costs of enterprises. Therefore, low nitrogen boiler is the best choice, but also the most sensible choice. To promote the implementation of environmental protection plan, accelerate the improvement of air quality, speed up the process of using low nitrogen boilers to reduce emissions of nitrogen oxides, nitrogen oxides and reduce PM2.5 due to the formation of the secondary reformer. Give us more space to control air pollution.
Analysis and pressure steam commercial boilers for sale burning issues of excessive treatment: this kind of boiler steam boiler, because it is an important site for the product, so in their knowledge and understanding of the, at least, should achieve a comprehensive and specific to this extent, so in order to further the product site, rather than just stay on the surface, and then, in the use of the product, there is a good use of effects. Therefore, in order to achieve the above objectives, the following will continue this topic, which reads as follows. 1. steam boiler, which is in use, whether the boiler must first obtain use permits, and then to use this kind of boiler? In addition, if classified according to their fuel, then, in particular, which has several? Steam boilers, because it belongs to special equipment, therefore, can not be directly used, relevant departments should first obtain use permits issued by the boiler, and then to use steam boilers. In addition, this kind of boiler, if classified according to the type of fuel, then, can be divided into three electric steam boiler, gas steam boiler and steam boiler fuel.Free Chat
