Effect of Exhaust Duct Position on Wood Vinegar Burning Process

Phineath Than and Keerati Suluksna
Abstract—This research aims to develop a burning tank and experiment for wood vinegar burning process using wood as raw material. To design, and operation of such burning tank require detailed understanding of parameters that affect the system performance. In the research, the device is designed for testing and developing a burning system that can improve the distillation rate of wood vinegar. The developed system consists of two tanks; burning tank and condensing tank. Burning tank made of steel with 400mm diameter and 600mm long for 15-20 kg of wood, provides tight airflow and has two exhaust ducts attached to top and bottom of the tank side. The condensing tank has 24 copper pipes with diameter of 12mm, and 400mm long, resulting in a condensing surface area of 0.36 m2. The condensing pipes are installed in a 65 liters tank contains cool water with temperature from 30 ˚C to 40 ˚C which is used as media for removing the heat from those pipe surfaces. In the experiments, two kind of woods will be used to test, fire conditions of air flow rate and moisture of woods are varied and two positions of exhaust duct are investigated. This developed system was tested on exhaust duct positions by using 15 kg Leucaena leucocephala wood with 5 hours, producing 3.39L and 4.21L by bottom and top duct positions respectively. The experiment results show that the interaction between the positions of exhaust duct is significantly effect on the yield percent of wood vinegar collected. That is the top position can increase the wood vinegar 24 % compare with the bottom position.

Index Terms—Exhaust duct, wood vinegar, experiment, parameters, burning tank.
