Hi Bruce, You Ask:

Not sure if this will help, but a lifetime ago when we worked with engine oil filtration, a rule of thumb said we produced exhaust water, gallon for gallon of fuel used. I remember that these figures came from Texaco, or Caltex for whom our advising Chemical Engineer worked. Clearly this would also be affected by atmospheric moisture. If you are fuelling with producer gas (I hope), then the H2 content will be a figure on which to focus, plus the atmospheric moisture. Keep in mind however, that producer gas, if that is the fuel, can carry a lot of humidity from the condensate even in Winter, as I have just experienced last week in N.California. From a practical point of view, we have found the exhaust moisture to have huge seasonal variations as experienced in our small wood block dryers, so a perfect answer may not be available if working with producer gas.
