This paper describes GASDS, a comprehensive model of a biomass gasifier on a travelling grate. This general mathematical model deals with the complex multiphase gas¬solid problem of biomass gasification both at the reactor and the particle scale. Mass and energy balances plus proper closure equations describe the behavior of both the phases. Key elements of the model are the detailed kinetic schemes describing the biomass volatilization, including the formation of TAR species and char, and...
