Gasification of biomass (wood, wood waste, agriculture residue, etc) is an often-discussed option that may permit electrical utilities to obtain a portion of their fuel requirements from renewable energy resources. However, the technical state of this option is unclear in Nepal at present, and this study was initiated to provide documented design guideline and performance testing information of commercially available and laboratory commercial prototype biomass gasifiers to electricity utility end user. To achieve this goal, several laboratory prototypes has been developed and rigorously...
