Abstract
Biomass, mainly in the form of wood, is the oldest form of energy used by humans. Gasification is a
process of conversion of solid carbonaceous fuel into combustible gas by partial combustion. In the present
study, a model developed by us in our earlier study is used for predicting the steady-state composition and
rate of reaction profiles for the reduction zone of the downdraft biomass gasifier are predicted. The effects
of moisture content on the composition profiles and rate of reaction profiles are studied. Boudouard
reaction rate and water gas reaction rate along the bed length and its correlation with gas compositions are
analyzed.
