Detailed Description

Char oxidation model given by Hurt and Mitchell:

Based on the reference: Hurt R. and Mitchell R., "Unified high-temperature char combustion kinetics for a suite of coals of various rank", 24th Symposium in Combustion, The Combustion Institute, 1992, p 1243-1250

Model specifies the rate of char combustion.

C(s) + Sb*O2 -> CO2

where Sb is the stoichiometry of the reaction

Model validity: Gas temperature: Tc > 1500 K Particle sizes: 75 um -> 200 um Pox > 0.3 atm
