27 Description
28  Char oxidation model given by Hurt and Mitchell:
29 
30  Based on the reference:
31  Hurt R. and Mitchell R., "Unified high-temperature char combustion
32  kinetics for a suite of coals of various rank", 24th Symposium in
33  Combustion, The Combustion Institute, 1992, p 1243-1250
34 
35  Model specifies the rate of char combustion.
36 
37  C(s) + Sb*O2 -> CO2
38 
39  where Sb is the stoichiometry of the reaction
40 
41  Model validity:
42  Gas temperature: Tc > 1500 K
43  Particle sizes: 75 um -> 200 um
44  Pox > 0.3 atm
