In this study we have developed a modified charcoal kiln for both thermal therapy and charcoal production. The kiln design placed emphasis on safety and cleanliness including charcoal quality. The modified charcoal kiln had two entrances for charcoal production and thermal therapy. A noxious gas barrier was also installed between adjacent charcoal kilns for thermal therapy. In addition, a fine dust collector was fitted to remove fine dust generated during the charcoal production. For the verification of this kiln, harmful substances and fine dust were measured after charring process. Also we compared some characteristics of the white charcoal made from the thermal therapy kiln and traditional kiln. For evaluation of charcoal quality for both kilns, anatomical and physical characteristics, calorific value and proximate analyses such as ash contents, volatile matter, fixed carbon and pH were examined. Consequently, the results of harmful substance and fine dust in the modified charcoal kiln for thermal therapy met the reference value of Atmosphere Environment Conservation Act, Ministry of Environment, South Korea. In addition, there were no considerable differences in the properties of the white charcoal produced from both kilns.
