摘要: This work proposes a simple and accurate tool for predicting the main parameters of biomass gasification (syngas composition, heating value, flow rate), suitable process study system analysis. A multizonal model based on non-stoichiometric equilibrium models repartition factor, simulating bypass pyrolysis products through oxidant zone, was developed. The results tests with different feedstocks (corn cobs, wood pellets, rice husks vine pruning) in demonstrative downdraft gasifier (350kW) were used validation. average discrepancy between experimental up to 8 times less than one model. factor successfully related operating conditions characteristics simulate (variation potentiality, densification mixing feedstock) analyze sensitivity.
