The forgotten ‘victim’ of the northern Uganda war
Gladys Oroma, Daily Monitor Only, Uganda June 4, 2008, http://www.monitor.co.ug

In times of war, what concerns people most are the effects of the insurgency on the people, not its effects on the environment among others things.

The war however, in northern Uganda has had severe effects on the environment, says a new report. Due to the conflict, there has been a change in the land cover over the last 18 years. The remote sensing analysis report shows that small-scale woodland covers have increased in the area in the past years.

According to the 2005 report, the woodland vegetation cover increase occurred in the districts of Kitgum, Gulu, Pader, Adjumani and Moyo while a significant decline in the woodland cover was registered in the districts of Apac, Kotido, Lira and Moroto.

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.
