Industrial production is inseparable from design calculation of fired boilers, emission control of atmospheric pollutants boiler air pollution control in Shanghai to expand and intensify the focus of the project. Currently, Shanghai Industrial boilers alternative clean energy has been completed, nitrogen oxides (NOx) emissions of major pollutants as a boiler, the boiler due mostly low shelf emission source of ambient air near the ground and ozone greater PM2.5 influence, therefore, this release the new standard, the boiler will be low-nitrogen transformation, improve Shanghai air quality, protect people's lives and health and other aspects demand a strong thrust of great significance. Throughout the country, Beijing, Tianjin and other places have started low-nitrogen transformation boilers for low-nitrogen transformation has a more mature technology reserves. Based on the above considerations, for the effective control of NOx emissions from boilers, to further deepen cooperative control of PM2.5 and ozone, according to the standard first, to further accelerate the transformation of governance principles, it is necessary once again to revise the standard boiler.
According to local environmental standards and revision procedures, the Municipal Environmental Protection Bureau held a meeting to hear the relevant departments, enterprises and the opinions and suggestions of experts, and in 2017 August 4 to September 15 in the online open standard full text to solicit public opinion. At the same time the Ministry of Ecology Environment solicit written opinions Municipal Development, City Commission by letter and other related commissioned Bureau, industry organizations and boilers, production units and other enterprises. Municipal Environmental Protection Bureau and the Municipal Quality and Technical Supervision on January 19, 2018 organized the expert technical review meeting, the panel agreed that standards through technical review. Approval by the Municipal Environmental Protection Bureau and the Municipal Quality and Technical Supervision audit report to the municipal government.
The new standard has been revised for several aspects, one is no longer on the "central heating boiler and the nominal amount of evaporation less than 65t / h boiler cogeneration" provisions alone time; the second is to simplify the original class standard boiler merged into " gaseous fuel boiler "and" boilers "categories; are three different degrees of contamination tightened limits particulate matter, sulfur dioxide and nitrogen oxides; four new boiler is implemented from the date of implementation of this standard, the boiler given a transition period of about two years.
New standards for gaseous fuel boiler particulate matter, sulfur dioxide and nitrogen oxides are applied strict limits, but mainly considering the control of nitrogen oxide emissions, and further improve air quality. In the transition period boiler (1 October 2020) to limit nitrogen oxide 150mg / m³; after a transitional period of 50mg / m³. Date of implementation of new boiler nitrogen oxides from standard starting execution 50mg / m³ limit. Taking into account the comprehensive utilization of straw in Shanghai, biomass fuel boilers follows the standards of the original project control and limit requirements.

Behind the low nitrogen design calculation of fired boiler explore three popular reason is to promote the boiler heat source energy economy of power, to bring convenience to people's lives at the same time, boiler emissions also increased air pollution. Low nitrogen boiler its high thermal efficiency, the obvious advantages of ultra-low nitrogen emissions, to get people's favorite. Low nitrogen boiler reason to get popular and widely used, is inseparable from the following three reasons. 1, strong environmental protection according to environmental requirements, the country's industrial vigorously implement the project boiler clean energy transformation of small coal-fired boilers to be changed to "oil, gas or electric boilers" and other new energy device. Especially in recent years in Beijing, Tianjin and the Northwest Regional haze serious, and therefore improve the national environmental emissions requirements for industrial boilers. Beijing, Zhengzhou, Xi'an and other places have implemented the most stringent in the history of NOx emission standards (air pollutant emissions shall not exceed 30 mg / cubic meter), to accelerate the marketing process low energy consumption low nitrogen boiler. 2, the combustion more fully and more economical combustion boiler technology to more advanced low-nitrogen, and it is mainly used FGR premix combustion technology, a relatively low index of pollutant emissions, and a more appropriate fuel ratio, the combustion more fully , can significantly reduce the overall energy consumption, and its flame propagation speed is relatively fast, relatively high intensity combustion, heat can be continuously supplied in order. According to the experts explain, low nitrogen boiler requires little worried about the problem of insufficient chemical combustion. 3, high thermal efficiency boiler is an energy conversion equipment, professional production of low-nitrogen boiler as available and high-grade thermal energy necessary for life, for gas boilers, machinery (solid) incomplete combustion heat loss and heat loss is negligible ash physical Excluding. Want to improve the efficiency of the boiler, the boiler only reduce heat loss and heat dissipation reduce exhaust gas temperature. These are fast boiler for your boiler to low nitrogen summary of the popular three main reasons, whether it is national policy or market demand, low nitrogen boiler is an excellent choice. If you have a problem there are other low-nitrogen boiler operation, maintenance and other aspects, can talk to our professional boiler engineers directly by phone or online, we will do our best to help you solve the problem.
The characteristics and stove works Here are just some of the basic information about our company stove. First, my company to develop and produce high-temperature hot stove can provide clean, sustainable source temperature, it has been widely used not only dried food, food, medicine, tobacco, animal husbandry, agricultural and sideline products and various kinds of industrial materials, printing, drying the paint and other heat sources, it can be used for tall plants, such as plastic greenhouse heating, and underground mines, underground engineering, where heating to be dried and lower humidity. Second, Yinxing Company and ship design calculation of fired boilers 713 Institute jointly developed the high school low-temperature hot stove technology heritage, good heating effect, won praise users. Third, the high temperature gas can be directly incorporated into the drying room intake pipe, since the stove burner can be achieved, automatic temperature control, so the stove will start automatically according to the temperature sensor, stopping, adjusting the combustion state, to achieve the intended purpose. The working principle of the heat exchanger and the combustion chamber stove into one, all-steel sleeve multilayer structure, which is the lower part of the reactor core combustor, and surrounded by an upper annular heat exchangers, air and flue gas are bis backhaul , prevails, for heat exchange. In order to improve the thermal efficiency using the principles of heat transfer technology and the long helical groove turbulence sheets, Save thin sub-layer, the air and flue gas are constantly changing during rotation, greatly enhanced heat transfer. The main process is: burning coal in the furnace to produce high temperature flue gas, enters a loop under the action of the fan, exchanging heat with the outside air, is discharged via the chimney flue; stove cool air blown by the blower housing, the outside air into the cavity top wall ring, a clean hot air from the duct supplying hot air device for an outlet.
