Innovation of Rotary Furnace to Make Shell Charcoal into Briquette to Increase the Yield of Product

Abstract

The purpose of this study is to innovate the drum tools used in the manufacture of shell charcoal, the process takes 8 to 10 hours, and a lot of smoke that causes pollution, as well as charcoal results obtained only 40%, so the purpose of this study is to increase charcoal results and accelerate combustion time and improve the quality of shell charcoal produced. The Rotary Furnace in this result has specifications: Stainless material and steel Drum Length 130 cm, Diameter 50.0 cm, maximum feed capacity 20 kg, minimum 3 kg The shell has maximum temperature are 300 oC. The innovation of Rotary Furnace has the best operation condition process is at temperature 200oC, the highest yield of 68% with the lowest % loss of 23.4%, the number of fireballs is 20%, and the operating time for making charcoal into briquette are 15-30 minutes.
