Introduction of coal fired steam boiler to Vietnam
1. Optimum structural design with fire&water mixing tube make smaller boiler volume and can save 1/3 building cost of boiler house
Environmental protection maintenance of boiler precipitator What Features boiler precipitator mainly refers to an important device to dust separated from the flue gas, and now it is very much application in boilers and industrial production, the purpose is to boiler boiler precipitator flue gas emissions of particulate gave out clean, so you can make our environment greatly improved, to avoid contamination, to let everyone know more about this device, let boiler precipitator manufacturers to introduce us its relevant characteristics. A, high degree of wear of boiler precipitator have very high wear resistance, which uses a very advanced composite domestic FRP resin during processing, such materials having strong corrosion resistance, and life is very the long-term. Second, a very small footprint and simple installation for such a device, it can choose outdoor or indoor at the time of installation, and installation occupied area is very small, it does not occupy more space, for users who use very easy. Boiler precipitator dust in the use of the process efficiency is very high, a lot of places that can be used, if users need it to complete the purification, can also be designed according to their specific dust mechanical equipment.
Industrial production is inseparable from maintenance of 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.
