查询词典 pollutants

For the proposed project the waste gas emission locations include: preheating furnace of hard alloy parts line (when natural gas is used for heating while excess heat heating system goes wrong), melting furnace, refining furnace, heat treatment furnace for machining unit and steam boiler. The pollutants are SO2, NOx and smoke dust contained in the smoke generated from the above locations. All the above pollution generating facilities use the most clean energy, natural gas, for burning. Meanwhile, on melting furnace and refining furnace low nitrogen combustion technology such as low NOx burner is applied, and the generated smoke is discharged via chimney.
