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

TLUDTLUD


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.

Naturl Draft Gasifier - KumarNatural Draft Gasifier - Kumar

N D G - BASICS & PRINCIPLES

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

UNIQUE FEATURES COMPARED TO CONVENTIONAL SYSTEMS

  • 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

More detail, schematic pictures and testing information are in the attached pdfs and in the 2004 discussion:

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.

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
atmosphere.

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.
