En la producción industrial moderna, eficiencia energética, environmental protection requirements, and equipment safety are becoming crucial components of corporate competitiveness. Entre estos, NOx emission control for industrial oil burners is particularly critical. NOx (nitrogen oxides) is not only a major cause of smog and acid rain, but also a core indicator in the environmental regulatory systems of many countries. Por lo tanto, understanding NOx emission standards and developing compliance strategies are essential issues that every company using industrial combustion equipment must prioritize.
What Are NOx Emissions and Why They Matter?
Industrial oil burners are widely used in industrial boilers, hornos de calentamiento, drying equipment, and various heat treatment processes. During combustion, nitrógeno (N₂) and oxygen (O₂) in the air undergo a chemical reaction at high temperatures to form NO and NO₂, which are what we call NOx.
The main factors affecting NOx emissions include:
Burner structural design
Fuel type and impurity content
Combustion temperature and flame pattern
Air-fuel ratio
Overall thermal efficiency of the boiler or furnace
Excessive NOx emissions not only damage the atmospheric environment but also lead to fines, production restrictions, or even shutdowns for businesses during environmental reviews.
Global NOx Emission Standards for Industrial Oil Burners
Different countries and regions have established different NOx emission standards based on their local economic level, industrial structure, and environmental requirements. The following are reference values for major regions:
