Downward Smoldering Fire Characteristics of Wood Chips and Wood Flour

Deep-seated fire that flameless combustion is one of the smoldering fires. It continues when fuel condensed state for heated by temperature. Deep-seated fire is toxic compounds many more than flame combustion. When that is no in case of heat source that is vulnerable, will serve as a middle step to generate a flame. However, causing deep-seated fire progress is not consistent. Also it is difficult to reproduce the experiment. The study is basic experiment for reproduce the deep-seated fire according to the density of the wood, deep as the basis for the experiment to analyze the burning rate of the fire. It is analyze that characteristics of the wood-flour and wood chips in the fire. Experimental container made of quartz was used in order to observe the eyes, the fire, the rate of progress in the vessel equipped with a thermocouple, to be able to measure the internal temperature. In addition, by using an infrared thermal imaging camera on the outside surface temperature was measured. Weight by measuring the reduction of deep-seated fire burning rate and calorific value of the correlation was derived.
