To promote energy conservation and reduce deforestation in the sugar cane growing in Western Kenya.

.1.2.1 Specific Objectives
To Promote TLUD gasifier cookstoves and five biogas planter in Western Kenya
To provide and service 20,000 TLUD gasifier cookstoves and 5,000 fireless stoves..
To train 150 women and youth groups in production, repair and sale of energy saving equipment
To train schools and communities on energy conservation and use of renewable energy technologies.
To develop an energy equipment workshop for production, service and sale of improved cook stoves and energy saving equipment.

The activities in the project will be
Community mobilization on energy conservation, forest resource management and effect of indoor air
Training in design, manufacturers and sale of renewable energy equipment and technologies i.e. biogas, TLUD gasifier cookstoves.
Networking on renewable energy conservation i.e. knowledge sharing and information dissemination.
Manufacture TLUD gasifier cookstoves, and five Biogas planters

This project will be carried out within the Nile Basin in Western Kenya. The same area is sources of Nile and other small tributaries. The project will promote energy saving culture and lead to sustainable use of forest resources while contributing towards the Kyoto protocol implementation. While noting that firewood is the major source of energy within the Nile basin and Methane, is 20 times more potent CO2 and hence its use in biogas energy is encouraged in managing green house effect.

Western Kenya has a population of over 5 million people of which 80% depend on agriculture for livelihood and over 70% use firewood as fuel source. A survey has shown that all boarding schools use firewood and charcoal as fuel for cooking hence pressure on forest cover. Sugar cane growing in Mumias, Malava and Bungoma is a heavy user of trees as firewood. This combined has led to heavy exploitation of forests and trees for firewood hence a danger to the water catchments area.

Sugar cane cultivation in western Kenya, which started in mid 1970’s, has accelerated the rate of destruction of trees due to high population density has further compounded the problem of destruction of forests and trees hence threatening the very source of water within the Nile Basin. Schools continue to put pressure on forest due to their high demand for firewood to use in cooking with highly inefficient open fire stoves. These project will develop biogas as an alternative source of energy, promote economical use of energy in institutions and homesteads through use of energy saving stoves create employment for people trained in production and service of the same and of the same and efficiently generate and use the highly potent methane from farmlands through biogas plants.

This project meets the requirements of MDG's and Partnership for clean indoor air broad objective. The project will support community driven effort and will address environmental threats on local scale within the Nile basin region in the area of development and use of alternative energy and construction materials. In the process of carrying out participatory planning and appraisals for Musamba, Matungu, Kholera and Khalaba, the villagers expressed the desire to get cheap alternative to fuel firewood energy and alternative to open fire 3-stone cooking method. In all this areas, villagers expressed their fears that trees are disappearing and as a result they use farm wastes like maize stalks for firewood. The same should be used to replenish soil fertility after the crop season and should not used in the kitchen as firewood. Others were resorting to cane trash and remnants.

Construction Plans for the “Champion-2008” TLUD Gasifier Cookstove (including operational instructions) Paul Anderson, March 1, 2009


The document attached contains detailed instructions for the construction of Anderson’s "Champion-2008" top-lit updraft (TLUD) gasifier that can be used in many different cookstove structures. On 18 pages with 39 Figures, the “Champ” is described in three versions (Hobbyist, Refugee and Artisan) with the same dimensions but using different materials and metal-working skills.

Design and Development of a Natural Draft Biomass Gasifier

Naturl Draft Gasifier - KumarNatural Draft Gasifier - Kumar


  • Operates under the principlle of “ Chimney Effectt ”
  • Natural draft caused by density difference


  • No blower is required for the operation
  • Automatically takes the required quantity of air for Gasification
  • Convey the Producer Gas formed by Gasification - Naturally
  • Reduced fuel consumption compared to traditional chulas

Coal Gasifier
Gasifier With Jet Burner

Fuel source for small-scale industry heating application is becoming expensive. This is more so for food, grain, and other processing industries in Indonesia where the energy sources for various processes are highly dependent on conventional fuel. At present, the cost of LPG went up to IDR 7,000 per kg while kerosene and diesel to as high as IDR 12,000 and IDR 5,500 per liter, respectively.

MJA Biomass Gas Stove

Alexis Belonio writes (edited and annotated by Paul Anderson and Tom Miles):

Attached is a picture of my latest coal gasifier stove. This
is the same basic TLUD stove I have for wood charcoal and wood chunks.

For domestic use, I use carbonized coal (or coke) as fuel instead
of the raw coal. Coal can be used for the stove, but we don't want to promote
this as a fuel since it emits poisonous gas. I would prefer to use coal for
industry application where gas can be cleaned before it is released to the

I provide only a small amount of coal fuel in the gasifier stove, enough
for cooking. This mean that the power output is only small and the
metal I use is a stainless steel.

I ignite the carbonized coal by using a wood charcoal that has been soaked in
kerosene as igniter. [This is a TLUD stove, so ignition is at the top.]

[In the Belonio TLUDs, the fan only blows the primary air. The
secondary air is
pre-heated as it rises naturally between the fuel cylinder and the outer
cylinder, finally exiting into the rising flow of combustible gases.]
The smoke in the coal gasifier I have was eliminated [combusted] by mixing
preheated air with the gas generated from the reactor. I think
there is no need of [forced] mixing the secondary air by creating turbulence
with the combustible gases. Because in that case, you will need a
slightly bigger fan with enough pressure to push the air.
