First, the use of clean electrical energy more environmentally friendly coal resources, in fact, has supported the development of the early industrial age but as to their social environment pollution caused by more and more serious, it is mainly the energy status as they are now gradually being replaced by coal to stainless electric boiler is one of the ongoing substitution process, electrical energy efficiency way to get more use of comparison is very high, the most important is the pollution generated by the use of a very small community environment this point has very important significance. Second, to reduce the use of coal ash to bring people hurt boilers Many are now in the winter heating coal to electricity boiler heating the most direct benefit to bring on include reducing soot damage, the use of coal boiler inevitable to produce soot, ash and these could seriously harm the long-term direct air to people's health, good quality coal to electric boiler is very good solution to this problem is to improve the health of everyone contributed very effective force. Third, reduce energy consumption while also reducing the use of clean-coal boiler difficulty is not very far and high efficiency of energy utilization for coal resources, so the electricity can replace coal in a certain sense, greatly reducing energy consumption and the use of coal is another serious drawbacks will generate a lot of garbage, the garbage will not only deepen the environmental pollution will increase the difficulty of people to clean up, so coal to power boilers can be said to kill two birds played a role in this regard.

Recently, the Changsha City issued a notice on the transformation of low nitrogen gas boiler related documents. Details are as follows:

1, a total transformation time for two years, 2019-2020 years.

2, the transformation range: High-tech Zone, Furong District, Tianxin, Kaifu District, Yuhua District, Yuelu District administrative region, the city of hope Gaotangling Subdistrict high Tong Ling Area, Osan streets Yujia slope Area, Lake Daze in the region ban on burning streets, white sandbar streets, moon Island street, Jinshan bridge street, Golden Park street, Xingsha streets of Changsha County, Hunan Long street, Quantang streets, Langli streets, long queue streets, such as the scope of the existing town of Sha It is not less than 1 ton of steam (greater than or equal to the rated power or hot water boiler, organic heat carrier in the boiler 0.7MW) gas boiler (facility) (boiler equipment including special directory outside the range) low nitrogen unit owners embodiments transformation. Or more areas outside the area of ​​self-implementation.

3, the transformation of the standard limits: the new replacement and overall gas boiler Changsha NOx emission is less than 30mg / Nm³; gas boiler (facility) was transformed with the nitrogen oxides emission concentration of less than 50mg / m³.

4, 2019 Task: In addition to the Furong District, Yuhua District, within a range of high-pollution fuel combustion zone ban other jurisdictions to start the transformation from June 2019, 50% complete gas-fired boiler (facilities) low nitrogen transformation and complete acceptance.

5, 2020 Tasks: Before the end of October 2020 to complete all gas boilers (facilities) within the range of high-pollution fuel combustion zone ban on low-nitrogen transformation and complete acceptance.

Steam boilers for industrial production of stable and high-quality delivery of steam, wide range of applications. Depending on the fuel, coal-fired boilers can be divided, biomass boilers, gas-fired, oil-fired boiler and an stainless electric boiler.

It may be suitably improved electrical steam boiler burner material: the electric steam boiler at the time of adjusting, if the wind speed control of the secondary is too small, it will lead to too close the gas fire, the burner nozzle so that thermally deformed until failure. Further, when the adjustment is not timely gas boiler load changes the level of the upper orifice of the secondary throttle will be cooled so that the burner is not burning. It may be suitably improved electrical burner of a steam boiler materials, steel materials excellent recommended to choose, and adding wear resistant features. Selection of swirler vanes refractory steel material, so to avoid burning due to swirling vanes configured fall burner opening deformation damage.
