On the heat of reaction in wood pyrolysis

摘要: A mathematical model describing the essential processes taking place in wood pyrolysis has been utilized with experimental data on cylinders to deduce value of heat reaction wood. The includes mechanisms for transient conduction, internal convection, variable properties, Arrhenius decomposition, and reaction. Using this experiment Roberts & Clough [Ninth Symposium (International) Combustion, Combustion Institute, Pittsburgh, Pa. (1963), p. 158] we find reaction, defined terms initial final reference states at ambient temperature, be endothermic. Some typical numerical results are also presented.
