Abstract

This invention relates to the development of a small Biomass or Dendro Gasifier of thermal capacity 15 KW. What differentiates this design from other commercially available small Biomass or Dendro Gasifiers of similar capacity is the fact that it produces wood gas or producer gas of low tar content without the need of water for scrubbing and cleaning the gas. Use of water for scrubbing makes the operation cumbersome and further the contaminated water containing phenols have to be properly disposed of. This design therefore offers a robust and standalone unit capable of easy deployment. Through the innovative design of the Hopper the moisture and the tar formed through pyrolysis are separated and removed before they can seep to the Firebox where the combustion of the wood and the reduction to wood gas or producer gas takes place. The design of the Firebox with custom castable fire concrete material raises the combustion area temperature and accelerates the cracking of the remaining tar, further improving the quality of the wood gas or producer gas.
