Please help me take a look at this document. What does low-nitrogen transformation mean? What is the content of low-nitrogen?
Each province and city have different standards. For example, the Beijing-Tianjin-Hebei region requires that the measured value of nitrogen oxide emissions cannot exceed 150, and Shandong cannot exceed 200.
There are a lot of things involved here, you can chat with me privately
For new coal-fired boilers in key areas, the nitrogen oxide emission concentration shall not exceed 50 mg/cubic meter under the condition of a baseline oxygen content of 6%. As long as the gas boiler has a reasonable structure, it can meet the requirement of no more than 30 mg/cubic meter in key areas after low-nitrogen transformation.
