Boiler is a kind of energy conversion equipment. Under the condition that other links of power station system have been developed and perfected, boiler combustion system has become the main link of energy saving and saving in coal-fired power station. At present, with the improvement of burner technology, it has been able to adapt to the combustion of all kinds of fuels and loads, but the new requirements of energy saving and emission reduction in electric power enterprises make the combustion of utility boilers not only meet the steady combustion, It also meets the requirements of high efficiency of combustion process and reduction of pollutant emission. Therefore, further optimization of combustion process and operation is needed. Today, we'll take a closer look at it.
How many mills 2 tons of wet back low emission 6 ton steam boiler gas prices for textile mills, coal-fired boilers with steam or before the, but the last few years, a lot of coal-fired steam boilers are being banned in various textile mills gas boiler come into play in the main. So now a lot of mills are purchasing gas steam boiler. For steam boiler purchase, many of the new plant are approximate estimation of their production capacity, for the manufacturers, the choice of the boiler, then, is the need for more detailed production data, this is the case, for determining the gas steam boiler tonnage there is a great help. After data analysis, the conclusion is that the mill with 2t gas steam boiler is very suitable. At present, the tonnage price of about 24 million. If there are more low low nitrogen emission requirements, the price will be higher some.
How much is the cost of the transformation of industrial boilers, industrial boilers transformation costs how much money? With increasingly stringent environmental policy, a lot of coal-fired boilers are in need of rehabilitation. For the cost of the required current business situation will have to see the boiler, if time is too long, then it has no value transformation, and not as a direct boiler for a new one for direct production. With more and more serious air pollution, people's environmental awareness is gradually increased, the country has issued a series of policies to combat air pollutant emissions, on the industrial boiler industry, small coal-fired boiler flue gas emissions contained in the dust, sulfur and nitrogen oxides can cause serious pollution of the atmosphere. Therefore, the coal-fired boiler to gas boiler has become a way now widely used. How much is the cost of the transformation of industrial boilers, to be determined according to need of rehabilitation component, location, and so on. In general, industrial boilers convert almost need to start from the following aspects: 1, removal of former industrial boiler auxiliary equipment; 2. Calculated by the heat transfer in the furnace, the furnace geometry is determined, the center position of the flame furnace, the furnace is re-injected, and after the original arch tube is made on the basis of the original slope. 3, installation of blast doors; 4. industrial boiler equipment 1.5 times the working pressure of the hydraulic tests carried out. Under normal circumstances, the pressure component of the boiler furnace should not be changed as much as possible, and only furnaces and furnace wall arch reform should be carried out locally.
For atmospheric environmental quality issues, Harbin City, Heilongjiang Province, submitted a gratifying annual summary to the people within the city. By 2018, the number of days Hashi ambient air quality standard of 310 days, an increase of 40 days, since the implementation of our 2013 new environmental quality standards, the best of the year.
January 2019, the development of ambient air quality continues to improve. "Good weather" gratifying is the result of Harbin in straw Jinshao, such as firecrackers ban on burning the same time force. Among them, strongly promote the elimination of coal-fired boilers is a top priority. According to statistics, in 2018, out of a total of 1191 Harbin coal-fired boilers to provide strong support to reduce emissions of air pollutants.
Harbin coal-fired boiler was closed down following a major way, into the central heating (including wholesale) or clean heating pipe network replacement. According to the principle "and the appropriate and, should the electric power, the gas should be gas", the clean coal central heating pipe network coverage area, the boiler unit according to claim ownership, the priority region incorporated central heating pipe network; in concentration not covered by district heating network, in accordance with the wishes of the boiler unit property, taking clean renewable energy or alternative heating means, out of coal-fired boilers.
At the same time, various related businesses also improved stations, actively cooperate with the phase-out of coal-fired boilers.
2018 Hashi out of coal-fired boilers intensity of the strongest of the year, out of range built-up area expanded from 9 to zone outside built-up areas, out of a total of 1191 units. In District 9 built-up areas, on the basis of 10 tons of steam per hour out of coal-fired boilers to achieve "clear" on the further elimination of more than 10 tons of steam per hour to 99 coal-fired boilers; county (city) district built out of steam per hour 10 116 tons of coal-fired boiler units; elimination of financial support and utilities per hour 10 tons of steam coal-fired boilers 966 units in urban and outside built-up areas in the 9th district. "Achievements accumulated over the years, significantly reducing the use of coal, reduce emissions of pollutants." Director of Air and Noise Pollution Control at the Harbin environment bureau, Li Bin Tang said.
"In order to further solve the pollution problems of coal-fired, 2019, Harbin plans in urban areas, the county (city) built-up area basically eliminated 10 tons of steam coal-fired boilers and furnaces and tea, operating the stove, coal grain storage and drying equipment coal-fired facilities; urban built-up area basically eliminated 20 tons of steam coal-fired boilers, push 35 tons of steam coal-fired heating boilers out of the urban built-up area can not be a stable discharge standards; outside built-up areas out of 10 tons of steam can not be stable discharge standards of the following coal-fired boilers. "Li Bin Tang said.
