| Abstract |
This research aimed to study the temperature efficiency of vertical charcoal metal kiln compared
between the original kiln and improved charcoal kiln with thermal insulation to prevent heat loss.
The computational fluid dynamics (CFD) model was used for analysis. The improved charcoal kiln
with thermal insulation to prevent heat loss to change airflow within kiln’s chamber. Components
of improved kiln consisted of; 1) The insulated cover lid made from fiberglass in cylindrical shape
with thickness of 10 cm., height of 100 cm., and diameter of 65 cm., wrapped with steel sheet 2 mm.
of thickness; 2) The metal combustion chamber in cylindrical shape, with 56 cm. of diameter, 89 cm.
of height and 0.2 m3 of capacity; 3) Metal grate placed 10 cm. inside the combustion chamber;
4) The kiln base for fuel input, with space for airflow to the chimney and for sand input in order to
prevent heat loss while testing; and 5) The 4 inches pipe-shaped steel chimney, with thickness of
2 mm. and height of 200 cm. The computational fluid dynamics (CFD) model found that the maximum
temperature was similar. When, it was compared the double layers vertical charcoal metal kiln to
prevent heat loss with the original kiln, it was found that the average temperature was improved
at 277.54K, the charcoal kiln temperature efficiency was improved at 51.47 percentage, the average
air velocity was improved at 1.26 m/s, of which resulted from the change of airflow direction (stream
line). |
