Anila Stove

Combustion Cycle

Magh CM-II natural draft woodgas stove http://e-maghcm-ii.blogspot.com/, it is a very low-cost stove for heating and generating charcoal. It can also be described as a mini-charcoal making metal kiln. Instead of incinerating biomass generated from home gardens / any other dry combustible material generated as household waste usually throw into the garbage bins, can be used here. The leaf litter, dry twigs / sticks, chips of wood, wood shavings, etc., are very much suitable.

MJA Biomass Gas Stove Burning Coal

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.

Anagi Stove Construction in Sri Lanka
ARECOP, Practical Action

The most popular ICS in Sri Lanka is marketed under the trade name
“Anagi”. The word “Anagi” in Sinhala language means precious or
excellent. So “Anagi” stove is very useful as it saves fire wood and
cooking time. Lab tests carried out on the stove indicate a technical
efficiency of 21 % and numerous field cooking tests indicate average
firewood savings over 30%...
