14t h coal fired steam cfb boiler shipped to argentina
The transformation of low nitrogen 14t h coal fired steam cfb boiler shipped to argentina should be noted that what matters for retrofitting low nitrogen boiler should be noted that what? Of nitrogen oxide emissions is large, complex sources, environmental problems caused by acid deposition, fine particles, ozone, nitrogen oxides and analysis of contamination status must be further strengthened. If you do not take further measures to reduce emissions, with the United States and the United States to speed up economic development, population growth and urbanization, nitrogen oxide emissions will continue to grow in China in the future. Based on current trends, by 2030, emissions will reach 35.4x106 tonnes, will inevitably cause serious environmental impacts. Therefore, we must effectively enhance the emission control of nitrogen oxides. From this we can see that low nitrogen boiler is imperative! A check device to check for low NOX combustion gas before commissioning is in place, the gas pipeline flow is clean, whether the valve is open. There is a burner pipe leaks, reasonable pipeline installation. Discharging vent pipe valve from the foregoing, to ensure that no mixing of the air duct, and the exhaust pipe should be connected to the outdoor. Second, stable combustion and combustion of homeostasis Remember, combustion adjustment is the basis for all of the low nitrogen burner adjustment, as long as guaranteed under any changes in operating conditions of combustion stability and combustion of dynamic equilibrium, to burn steam temperature influence is even greater. Since the steam temperature is a sign flue gas heat value balance between the steam and heat absorption, this can be maintained as long as the dynamic balance, steam temperature can be kept stable. Third, the level of flame boiler boiler central flame center is also an important factor in high impact low-temperature steam. In the high temperature steam operation, the amount of coal combustor exhaust can be reduced, the amount of the lower stage burner of coal may be increased, and vice versa. Running low nitrogen burners, it should also be noted effect of different combinations of temperature steam mill. Steam at a low temperature exhaust composition regulating a large margin, the combination of the high temperature exhaust temperature adjusting stage so small margin overheat. It should be strengthened and soot blowing air distribution according to the situation.
The whole structure of normal pressure BoilerThe whole structure of atmospheric pressure 14t h coal fired steam cfb boiler shipped to argentina consists of boiler body and auxiliary equipment. The main components of boiler, such as furnace, boiler barrel, burner, water-cooled wall superheater, economizer, air preheater, frame and furnace wall, constitute the core part of steam production, which is called boiler body. The two main components of the boiler body are the furnace and the drum. The furnace, also known as the combustion chamber, is the space for fuel combustion. The furnace in which the solid fuel is placed on the grate is called a layer furnace, also known as a bed furnace; the liquid, gas or powdered solid fuel is injected into the furnace burning in the fire chamber, which is called a chamber furnace, or a fire chamber furnace; the air turns coal particles into the furnace, which is called a chamber furnace, or a fire chamber furnace; the air turns the coal particles into a chamber furnace, also known as a fire chamber furnace. It is called boiling furnace, also called fluidization bed furnace, in which the furnace with boiling state and suitable for burning inferior fuel is called boiling furnace, and the cylindrical furnace which uses air flow to make coal particles rotate at high speed and burns intensively is called whirlwind furnace. The furnace design needs to take fully into account the characteristics of the fuel used. Each boiler should burn the original fuel as far as possible. The economy and reliability of boiler operation may be reduced when the fuel with different characteristics is used.
The third reason is that the amount of nitrogen oxide released during operation is very small. Most heating equipment such as ordinary 14t h coal fired steam cfb boiler shipped to argentinas need to use coal materials as raw materials when they are in operation. Materials such as coal generally release a large amount of hazardous air-quality substances when burned. The condensing boiler uses the steam produced by natural gas combustion as the raw material when it is in operation, so the nitrogen oxide content released during the operation is much lower than the prescribed standard. The analysis of the reason for the year-by-year increase in the sales of condensing boilers has come to an end for the time being.
Zhejiang Yiwu issued the "Yiwu winning Blue Sky Battle 2019--2020 action plan." Plan to improve air quality, enhance people's happiness index target put forward concrete measures of implementation, as follows.
1, vigorously develop clean energy. In-depth implementation of the "creation of a national clean energy demonstration Zhejiang Province Action Plan (2018-2020 years)" "Zhejiang three-year action plan for natural gas development (2018-2020 years)" and "Jinhua" Thirteen Five "Renewable Energy Development planning". According to "gas of the gas should be '' should the electric power" principle, energy companies actively guide clean energy alternative embodiment, in 2020, the proportion of the power in the final energy consumption of clean energy consumption accounting for the higher level, the city gas consumption amounted to 150 million cubic meters.
2, control total coal consumption. Strengthen energy consumption and total energy consumption intensity dual control, strict new coal project access, new (modified, expanded) construction project coal consumption reduction of coal instead. By 2020, the city's total coal consumption by 2015, down from more than 5%. Continue to promote alternative energy coal and oil, replace reached the national requirements. No new 35 t steam / hour or less polluting fuels boilers. Strengthening coal quality control, promote clean coal utilization. Before the end of 2020, clean coal utilization rate of 92%, the proportion of electricity than to accept deliveries in 2017 significantly increased.
3, to carry out comprehensive improvement of coal-fired boilers. Increase efforts to eliminate small coal-fired boilers, the urban built-up area basically eliminated tea furnace, operating a stove, grain storage and drying equipment, coal-fired facilities; basically out of 10 steam tons / hour and 35 steam tons / hour coal-fired boilers. 35 t steam / hour and more polluting fuels boilers completed ultra-low emissions and energy transformation. Low nitrogen gas boiler basically completed the transformation. Strict control of the new urban area of biomass boilers. Biomass boilers should be dedicated boiler, blended prohibit other fuels such as coal, and other supporting efficient dust bag embodiment, non-coal, oil, natural gas-fired boilers and the like directly Burning biomass briquettes.
4, the positive development of central heating. Cogeneration units to increase the technological transformation efforts, speed up the heating pipe network construction, improve the heating capacity and the full release before the end of 2020, phasing out the cogeneration district heating pipe network coverage and high pollution coal-fired boilers in the range. In the area where no cogeneration district heating conditions, a plurality of existing small coal-fired boilers, an alternative construction of large-capacity coal-fired boiler in accordance with the principles of the reduction or the equivalent.
5, deepening the construction of high-pollution fuel combustion zone ban. According to "adjust Yiwu prohibit the use of polluting fuels sales area plan" (Yi Zheng Ban Fa  No. 180) documentation requirements, a comprehensive investigation and eliminate high-polluting fuel facilities within the city, to ensure that no dead ends, no blind spots, Finish high pollution fuel combustion zone ban burning building before July 2019.
6, improve energy efficiency. Vigorously develop, promote energy efficient technologies and products to achieve key energy industries, energy-saving equipment standard full coverage. New energy-intensive projects per unit of product (output) energy consumption should reach the international advanced level. Local conditions to improve building energy efficiency standards, and increase efforts to promote green building, city guide implementation of green building standards for new buildings. Renovation of existing residential buildings to promote energy conservation, encourage rural energy-saving housing.
