✦ Synopsis

An experimental and modeling study of cellulosic char combustion under laminar gas flow conditions was conducted covering the temperature range of 473-1173 K with 0.03-0.21 oxygen mole fraction in the feed gas. A gas film mass-transport limited model accurately fits the combustion rates measured in a large-scale thermogravimetric furnace. The best fit correlation to the experimental data predicts that local mass transfer rates are governed by the relationship Sh x = 0.221 RexΒ° 564Scl/3
