A NATURAL GAS HAS THE FOLLOWING ANALYSIS BY VOLUME:
METHANE (CH4) 87%, HYDROGEN 5% AND NITROGEN 8%.
DETERMINE:
A) THE MINIMUM VOLUME OF AIR NECESSARY FOR THE COMPLETE COMBUSTION OF 1 m3 OF THE GAS.
B) THE VOLUMETRIC ANALYSIS OF THE EXHAUST GASES IF 20% EXCESS AIR IS SUPPLIED.
The volume of air required for combustion of a natural gas mixture is calculated. The volumetric analysis of the exhaust gases is also calculated.
