Automatically Controlled Solid-Fuel Gasifier Stove

Research Director: Professor E.C Ejiogu
Research discipline: Bio-Energy

This invention describes a new type of stove that in situ converts solid fuels into synthetic (syn) gas and thereafter burns the gas cleanly to produce a bluish flame similar to gas combustion of natural gas stoves. The types of solid fuel suitable as fuel include, but not limited to, coal, charcoal, pelleted/briquetted sawdust, rice husk and other agro-wastes products. To increase the versatility of the stove an automatic control system is designed for the automatic supply of air.

Significance of Invention

  1. We have described a new type of stove that coverts various types of solid fuel into synthetic gas for a clean combustion. The invention also includes an automatic control system to supplies air to the combustion chambers to provide regulation for combustion. The invention is a vast improvement on the existing liquid (kerosene) or charcoal stoves, in terms of performance and clean combustion.
  2. Environmental Friendliness and Merits over Existing Stoves
    1. Ability to utilize several types of cheap solid fuels, such as agro-waste, saw dust, coal, etc.This makes it environmentally friendly and cheap when compared to cost of kerosene
    2. Combustion can be controlled automatically and a pure blue flame achieved
    3. Ease of ignition and operation
    4. Suitable for rural areas and urban areas
    5. The stove can be made more functional by adding a Thermo-Electric Generation (TEG) device that will enable rural dwellers charge their cell phones.
    6. Ease of manufacturing, using locally available materials
