> Depends upon what else is in the gas. Typically "tarry gas" will also have 
moisture in it which reduces the heating value of the gas depending upon the 
feedstock and natural production of water in the gasification process. The 
problem with dirty gas is that you can't pipe it very far, control it's flow, or use 
it in any process equipment without contamination and frequent clean out. 
     If the water is removed from the gas, the heating value goes up and the 
ignition temperature is lowered. It also increases engine operating output due 
to higher overall thermal input to the engine. 
     Engine lifetime is shortened if the water is allowed to go into the 
engine becuase the organic acids contained in the water will eat the engine up 
over time.
