nitrogen in coal mill

Feed tank for ammonia
Application To protect the environment the nitrogen oxide content in the flue gas is reduced as much as possible This is accomplished by adding air and ammonia to the flue gas Through a chemical reaction the nitrogen oxides NOx are transformed into water and nitrogen The required ammonia NH3 is supplied from feed tanks.
