    Fuel Gas flow is 29.1 Kg/ sec
    The flue Gas Temperature after boilers is 180 C
    Please provide conversion for 67 Grams/ second of NOx to mg/ Nm3

    You would have to determine the exhaust gas flow that the 67 g/s of NOx is mixing with. The only easy part is that 67 g/s is 67 000 mg/s. You need exhaust gas lfow in Nm³/s

    Most emissions requirements must be reduced to a standard value of excess air to avoid diluting to meet, so you need at least the exhaust volumetric flow, and % oxygen in the exhaust gas.

    If you know your fuel gas composition (natural gas is a mixture) you could work out the mix at stoichiometry, which would have no O2, add sufficient excess air to make up the standard O2 number and compute exhaust volume, then reduce actual temperature and pressure to volume at normal conditions. It would be easier to measure exhaust gas volume.
