Charcoal Making in Clay Stove

Charcoal Making in Clay Stove

 

Clay Preparation

 

1. At the center of the oven, stand a 2 meters straight wood which will serve as support for wood to be arranged perpendicular to the oven.

– Shorter cuts of wood will be arranged around the center until it reaches the wall of the round pit of the oven.

– Use only woods which grow easily like ipil-ipil, bakauan, pototan, kakawate, kamachile, anabiong, tangal, agoho and alibangbang.

– Add small cuttings of wood on top of the first layers of wood in order to help mold the top walls or roof of clay.

Modified Drum Kiln

Modified Drum Kiln

 

1. Use an ordinary drum with 91 cm tall and 57 cm in diameter (55 gal).

2. Make a hole on top of the center about 10 cm wide (where the chimney can be placed).

3. Make equal holes on four sides about 1.5 cm in size and 30 cm spaced apart from each center, but the lowest is 2 to 3 cm from the bottom. (For example the second top is 30 cm apart from here then the third is the same).

 

Operation:

1. Place a piece of roundwood, about 4 inches in diameter at the center of the kiln.

2. Stack coconut shells around this makeshift chimney until the drum is full.

3. Remove the starting chimney and drop a piece of burning rag to the bottom of the drum until it ignited.

4. Cover the drum when the fire is well underway.

5. Gradually decrease the air opening.

6. Feed additional shells after sometime, when the volume of the charge shell have shrunk.

7. Carbonization is considered complete when the volume of the smoke thins out and becomes bluish.

8. When this happened all the holes are closed and the kiln is left to cool.

 

This procedure last 5 hours to finish charcoal making. The charcoal yield with this kiln design ranges from 27-30 per cent.

 

Tips for Good Quality Charcoal

 

1. Shiny and black in color, not reddish or greyish.

2. It sounds like metal when it falls on the floor. A good charcoal easily breaks but uncooked

charcoal is hard and doesn’t break easily.

Modified Method of Charcoal Production

Modified Method of Charcoal Production

 

The highest form of charcoal comes from wood or coconut shell burned under controlled air.

About 75% of energy we use comes from wood and charcoal fuel.

The customary or usual method of charcoal making was to answer the needs of barrio people

and to lessen the problem of forest denudation.

There are many types of charcoal making, the easiest is the use of excavation or pit and use

of drum. The principle of charcoal making is by heating the wood or coconut shell until dried

leaving only the carbon. This can be done by burning slowly under controlled air. If it is not

done this way the charcoal will turn into ashes.

The best method is by burning in a low fire and the smoke circulates within the wood and

coconut shell that are being made into charcoal.

Plants – Possible Sources of Energy

Plants – Possible Sources of Energy

There are many plants where we can derive energy not only as fuel but also as raw materials

for power generation such as oil, sap or turpentine. These could be processed into petroleum,

gasoline and related products. Some of these plants are:

 

1. Petroleum fruit — this is commonly called abkol, oil, dingo, sagaga and salkel. The plant

generally grows in Cebu, Bicol, Palawan, Nueva Ecija, Nueva Viscaya and Benguet.

– The fruit can be used for medicine aside from fuel. 52 grams of concentrated oil can be

taken from a kilo of this fruit and another 16 grams of oil can be expelled when the residue is

grinded.

– According to Phil. Pigment and Resin Corporation diagnosis, the fruit contains 12.35 of

leptine (one of the elements of gasoline) of oil.

– The plants can be propagated through seeds and twigs.
