Description

The quantity of NOx in a furnace stack outlet depends upon Nitrogen in fuel (particularly for coal). NOX however is also formed by the fixation of Nitrogen in the combustion air and this depends upon many factors but primarily flame temperature, residence time in the furnace and the turbulence in the furnace (design features) that is why calculation of NOX is not as straightforward as calculation for SOX

Properties provided are rando random intermediate value for a mixture of approximately ⅔ NO and ⅓ NO2.
