Optimization of Operating Conditions of a Household Up-draft Biomass Gasification Stove

Experiments were carried out with a household up-draft biomass gasification stove to investigate effects of the air distribution method on the performance of the stove. The temperature distribution along the gasifier, the producer gas composition, the stove power, and the thermal efficiency were inv...

The temperature distribution along the gasifier, the producer gas composition, the stove power, and the thermal efficiency were investigated.
