Safety aspects in small scale biomass combustion Fuel Handling Slide 12 Experimental studies for determining self-heating Scales grams: 4 m 3 : 1 dm 3 : 1 m 3 : Dublin 2011/10/18
Safety aspects in small scale biomass combustion Fuel Handling Slide 19 Self-heating and spontaneous ignition • Microbiological activity generally not significant (as in e.g. piles of wood chips) • Heat from oxidation of wood constituents • Oxidation of unsaturated fatty acids proposed to be major heat source • Self-heating often seen shortly after production • Some fuel qualities show higher heating activity and can during unfavorable conditions lead to spontaneous ignition Dublin 2011/10/18
