Abstract

Traditionally, the burning of wood cribs has been divided into a surface area controlled regime, and a porosity controlled regime according to mass loss rate. In the two regimes, the concentration of CO produced should also have different characteristics. In this paper, the variation of concentration of CO produced by burning wood cribs is studied. A series of experiments with different wood crib structures are conducted. The mass loss rate and the concentration of CO are measured. It has been found that the concentration of CO has an obvious transitional state, and the corresponding transitional value of porosity factor for dividing the two burning regimes according to the concentration of CO is exactly the same as that according to the mass loss rate.
