    The cost of frying food products for small-scale industry bake shop is now becoming expensive brought about by the ever-increasing cost of LPG fuel. Based on the experience of Sakura Ampan Bakeshop in Jakarta Pusat, Indonesia, a single-burner gas stove consumes about 2.2 kilogram of LPG per hour. With the present cost of LPG of IDR 350,000.00 per 50-kg tank, the bakeshop is spending around IDR 15,400.00 per hour for cooking and/or frying food products. For 8 hours operation per day, around IDR 123,200.00 is spent for its cooking/frying activities using LPG.

    Coal, which is abundant in supply and so far the cheapest of the fuels available in Indonesia, is the only alternative fuel to LPG that is considered economical and feasible for small-scale industry use. However, the emission of sulfur dioxide (SO2), which is the predominant reason for the unacceptability of this fuel among households, makes the use of coal unpopular for industry application. Nevertheless, this problem is now resolved by gasification. Injecting lesser amount of air to the coal bed during gasification in the stove greatly reduced the amount of SO2 emission as compared with the conventional direct combustion burning of fuel. By gasification, coal can be conveniently used with almost no SO2 emission during cooking.

    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.

    This prototype was to check the hole of the briquette and how gasification can do a nice job. As said, starting the fire with few small sticks and then after preheating the chamber, briquettes ignite by themselves and burn throughly. You can help flames with having a stick in the hole while burning. I really liked how the briquette retained its shape after it burned out, so you could still push the next one it without preventing the draft..

    But the briquette burned with the surface lit from the combustion chamber, as Larry predicted. You could literally walk away of the stove with the consistent flame going on all the time (I guess the briquettes were good quality :) The air inflow was only through the hole of the briquette.

    Funny was, that even when one briquette burned out, the next one ignited and the airflow continued through the hole of the first briquette.

    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.
