HEAT CAPACITY OF AIR SUPPLIES AND GAS. POINTS FOR CURVES AND TO
BE USED IN SPOTTING THE INTERSECTIONS JNDICATING THE EFFECTS
OF PREHEAT

This particular producer gas is rather high in CH4 which will have a
tendency to dissociate at high temperatures. This has not been considered
in order to find the limiting combustion conditions due to air supply.
