Abstract:
This research is to compare the quality of charcoal obtained from the production process of a 200 liter smokeless charcoal furnace to produce high quality charcoal. The researcher has improved the smokeless stove model. and insulating By using bamboo as the main raw material to produce charcoal. Studies have shown that the average temperature of an insulated charcoal stove is higher than that of an uninsulated charcoal stove. Because the charcoal stove has added insulation. This will cause the charcoal stove to have an average temperature inside the stove. The highest mean temperature was 739.5 °C at an average ambient air temperature of 27.3 °C, while the non-insulated had an average temperature of 477.9 °C. The maximum absorption of iodine number 910.45 mg/g and has a maximum specific surface area of 172.51 m²/g and the pore volume of the charcoal at 0.082566 cm³/g and has the highest calorific value of 7,177 cal/g has a heating value higher than the standard Community Product Standard at 5000 cal/g can be concluded that The insulated charcoal furnace is most suitable for burning bamboo charcoal with a 200 liter smokeless charcoal furnace when studying its economic cost. 200 liter smokeless charcoal insulated furnace In order to produce high quality charcoal, it was found that the investment cost was 7,500 baht and the investment could be returned within 39.5 days.
