Combustion Characteristics of Moroccan Wood Species and of the Wood Constituents

Abstract

The thermal treatment of Acacia wood and of the wood constituents
(xylan, cellulose and lignin) was studied by thermogravimetric
analysis in an inert (nitrogen) and an oxidative (oxygen)
atmosphere. Combustion of wood can be described in terms of
different steps, namely preheating and drying of wood, followed by
devolatilization of the constituent hydrocarbons. the solid residue
then combusts in the presence of oxygen. The wood constituents
combustion differs in position and shape. The lignocellulosic
materials are less reactive in nitrogen environment than under a
flowing oxygen atmosphere.
