Gasification of Coal, agro-waste, and some components of municipal solid
waste to energy for thermal and electrical applications has attracted attention
in the recent past. The work is in progress on high ash garden waste, its
kinetics, and performance in a small downdraft gasifier. The present work involves
further experimental and modeling studies in the downdraft gasification of this
feedstock. The focus is on understanding the cause behind tar and particulate
emissions and their dependence on various parameters.
