Analysis of the Imbert downdraft gasifier using a species-transport CFD model including tar-cracking reactions

Energy Conversion and Management, 2020
Primary tar reduction is an effective method to diminish tar concentration in producer gas obtained from a downdraft biomass gasification process. It tends to be more economical than secondary tar reduction in post-gas-cleaning processes. This study used
