Dear teachers, how are nitrogen oxides formed in sulfur-containing flue gases? What are the influencing factors?
Nitrogen oxides are divided into two types: thermal (also known as combustion-type) and chemical types. The thermal type refers to the formation of nitrogen in the air under high-temperature conditions (1200 degrees), while the chemical type refers to the conversion of nitrogen in waste gases, waste liquids, or fuel gases into nitrogen oxides.
The thermodynamic type is produced in large quantities only at temperatures above 1200 degrees
