Low nitrogen transformation

Among the pollutants from boilers, nitrogen oxide emissions have the greatest impact on the atmosphere. Therefore, in the national and local boiler pollutant discharge standards, the control of the index is the most strict. At present, the emission limits of NOx from gas-fired boilers are the most strict, which vary from region to region and require about 30-200. If some boilers are installed earlier, the current nitrogen oxide emissions of boilers in the region are more stringent requirements, and the exhaust emissions after combustion of the burner cannot meet the latest standards for pollutant emissions established by the state, then it is necessary to carry out low-nitrogen combustion transformation, which is mainly the transformation of gas boiler burners at present.
