Re: NOx Emission

In cement kiln operation NOX is the indirect indication of the burning zone condition. The normal range is between 1000 to 1500ppm. Anything less than 500ppm is the indication of dull burning zone and incomplete combustion ( CO formation).

Ofcouse minor variation will be there in the above value depending on the rawmix and kiln type
