I have a program that will calculate the dew point if you know the composition of the fuel gas and the excess air. The program also takes into account the air humidity, so please supply the ambient dry bulb and the wet bulb temperatures of that is available. Best Regards,

The simplest way would be to determine the actual dew point of the engine exhaust. If you knew this, and the actual exhaust temperature, you could then assume the exhaust was the same as air, and use high temperature air tables to reasonably estimate the additional moisture it could hold. One concept would be to find a glass tube, and flow a portion of the exhaust through it. Shove a thermocouple into the other end of the glass tube, to the point where condensation is first seen on the inside of the tube, and the temperature reading should be close to the exhaust gas dewpoint.
