| Abstract: | In order to qualitatively understand and evaluate the thermo-fluid dynamic situation within a wood gasification reactor, a 1D particle model has been created. The presented tool accounts for the highly in-stationary, kinetic- and thermo-chemical effects, leading to partial gasification and combustion of a wood particle embedded within a packed bed collective. It considers the fluid- dynamic situation within the changing porous bulk structure of the packed bed, its impact on species – and heat transition mechanisms, the energy – and mass balances of wood, coal, pyrolysis-gas, wood- gas and off-gas phases, the thermodynamics of locally developing gasification – and combustion reaction equilibria, as well as the presence of the chemical species hydrogen, water, carbon (di-) oxide, methane, oxygen, solid carbon and gaseous, longer chain hydrocarbons from pyrolysis. Model results can be shown to yield very good, qualitative agreement with measurements, found in literature. |
