Thermochemical equilibrium modeling of a biomass downdraft gasifier: Constrained and unconstrained non-stoichiometric models

Also the gasification of Brazilian Pinus elliottii in a downdraft gasifier with air as gasification agent was studied. The input parameters considered were: (a) equivalence ratio (0.28-0.35); (b) moisture content (5-20%); (c) gasification time (30-120 min) and carbon conversion efficiency (80-100%).
