Effect of the Flue of Charcoal Retort Kilns on Production Charcoal Using Drum Kilns for Households

Abstract—Experiment was carried out to obtain the more charcoal and decreased ashes and exhaust gas after production. Effect of the installation of the flue of charcoal retort kilns on production charcoal was investigated. In this study the product from charcoal retort kilns consists of weight of charcoal, ashes and gas exhaust from process. The charcoal was produced in 0.2 m3 of the vertical drum kilns. The results indicated that weight of charcoal increased 7.38 % whereas the weight of ashes decreased 18 % at the flue was installed within charcoal retort kilns. Moreover, the gas exhaust from process at the flue was installed inside charcoal retort kilns less than the gas exhaust at the flue was installed outside charcoal retort kilns. Furthermore, the efficiency of charcoal kiln where were installed outside and inside of charcoal retort kilns were 29.83 % and 32.63 %, respectively.
