The fire was started by spontaneous combustion in linseed oil-soaked rags that were improperly disposed of after use. I was just reading in the paper a couple of days ago about a place that was burning what they called hog fuel. The spontaneous combustion process begins very slowly and the heat of the reaction increases until combustion occurs. Compost Fundamentals: Compost Needs Temperature. The primary uses are as fuel for air-breathing engines and as a propellant. The owner's living quarters were on the second level of the hangar. Indeed, there is a wide variety of suitable combinations of organic fuel, oxygen-containing substances, and energy sources that will result in combustion. Once the conditions are met for heat to build up to a critical range, a small change in the external temperature can trigger a dramatic temperature rise. For spontaneous combustion to happen, the first event that must happen is high microbial activities during the decomposition of organic matter. As the mist emerges from the pile, condensation on the surface discolors the compost around the vent.
