摘要: Abstract Analyses appearing in the literature on combustion of cellulosic fuels assume that energy transfer fuel interior is adequately described by an unsteady state conduction equation provided with Arrhenius source. It has been discovered experimentally x-ray photography even though certain zones space and time above assumption valid, there exist other which several ‘secondary’ physico-chemical effects evolution become non-negligible take a dominating role control burning rate. The present paper gives critical summary processes mass transport wood-burning, attempt to formulate them such way meaningful quantitative handle possible. An presented calculate specific gravity moist wood as function porosity, ambient temperature humidity. fibrous nature demonstrated. A thorough discussion pre-d...
