Wood smoke particles from different combustion phases

The differences in chemical composition between the high-and medium-temperature wood smoke samples reflect differences in combustion conditions.The 3300 times higher level of refractory elements in the high-temperature compared to the medium-temperature wood smoke sample is in agreement with the potassium K-shell absorption edge observed only Wood smoke components and functional properties Aug 29,2016 The Chemical Composition of Wood Smoke#0183;The origin of the compounds in wood smoke is the polymers in the wood and the heat-induced chemical reaction between the heated polymers,gasified intermediates,and moisture.Thus,the composition of wood smoke will vary with the type of wood used in producing the smoke and the temperature and moisture content of the wood.Wood main chemical propertiesElemental chemical composition of wood of different breeds is practically the same.Absolutely dry wood on average contains 49% of carbon,44% of oxygen,6% of hydrogen,0.1-0.3% of nitrogen.When burning wood remains its inorganic part - ash.The composition of the ash includes calcium,potassium,sodium,magnesium and other elements.
