Fuel Moisture Influences in Log Wood Combustion

H. Hartmann & P. Turowski
Combustion tests with a common 30 kW downdraft log wood boiler and a 6 kW chimney stove were performed to determine the effect of a variable fuel moisture content in wood log combustion. Fuel moisture content was varied between 8 and 36 % with the boiler and between 1 and 18 % with the stove. The results show higher pollutant emissions when the moisture content rises above 25 % (mainly CO and particles). Below this...
