The extent of the reaction in oxygen- and water vapor-bearing flue gas is described as a function of the fraction of solids ejected into the freeboard from the bed surface, the relative throughput, the gas density, and the global rate of reaction. Experimental measurements were conducted to determine the axial concentration profiles of carbon monoxide and other species throughout the freeboard. Steady-state measurements were carried out in an electrically heated reactor with an inner diameter of 9.36 cm above a gently fluidized bed of heat-resistant ceramsite particles in which a precursive liquid fuel (isopropanol) was burned.
