Thaba Tseka Biomass Stove

[reducing amount of wood fuel needed for cooking and heating]

[Summary & Motivation] [Community] [Specifications] [Issues] [Contacts] [Diagrams / Pictures]

Summary & Motivation
Project Initiator: ATS
Start Date: Before 2003
Projected Completion Date: Before 2005
Current Status: Production and refinement

Lesotho is a country with a very low amount of available biomass for burning. Using an open fire to heat and cook is inefficient (Around 8%), so ATS has been working to develop a stove that requires less fuel. The thaba tseka stove was developed by the now defunct Thaba Tseka Technical Institute (Hence the stove's common nickname of the "TTI Stove"), and it can use coal and cow dung in addition to wood. The stove allows for increased efficiency by funneling the heat upwards towards two steel burner plates. Currently, the stoves have an efficiency of around 28%, and they are one of the more popular items available at ATS.

Community

This technology would be marketed to rural women who currently use open fires to cook their food products. The stove would be used by a single household.

Specifications
  • Must produce both heat and warm cooking surface
  • Should not create harmful household environment
  • Should fully combust biomass (Efficient)
  • Light weight
  • Affordable

[top]

Issues

Help is needed in the following areas:

  • Developing a stove which both efficiently heats and cooks
  • Reducing weight of current stove
  • Preventing smoke from exiting at weld joints (Should only exit at chimney)
  • Designing a way for stove to hold three-legged pot
  • Developing insulation to make stove more efficient
  • Evaluating other materials for construction, including alternatives to steel
  • Reducing product cost so that the stove is an attractive alternative to collecting wood
  • Privatizing production
