การปรับปรุงรูปแบบและเทคนิคการผลิตถ่าน ด้วยเตาขนาด 200 ลิตร

Abstract

This research aims to comparative the quality of coconut shell charcoal obtained from the production charcoal kiln process of 200 liter by improve model with production charcoal. Using the 84 generation charcoal burners, the cone device was added to the combustion chamber. Made of 200 liter fuel tank. The researcher added insulation 3 types insulation are soils, sandy and rice husk ash. The study found that the insulated charcoal kilns have an average temperature higher than the non-insulated charcoal kilns because the insulation has the ability to block the heat from the inside of the stove does not heat transfer to atmosphere easily. Reduce the heat loss of charcoal furnaces and reduce the time to burn charcoal and rice husk ash insulation has a maximum temperature of 735.1 degrees Celsius. The time it takes to turn off the burner is 70 minutes. The amount of charcoal produced is 4.6 kilograms at a starting volume of 25 kilograms. From the iodine number test found that charcoal kilns used rice husk ash insulation had the highest iodine number value 910.4461 mg/g and has a maximum specific surface area 172.5114 m²/g and the porous volume of charcoal at 0.082566 cm³/g and has a maximum heat value of 7,177 cal/g
