Abstract: This paper reports the first use of a charcoal processing system with an internal combustion furnace (CPSICF) to produce pyroligneous acid from rice husk, called rice husk vinegar. The gate width in CPSICF influenced air intake, which directly affected the temperature of the furnace that played a key role during pyrolysis. The process characteristics of rice husk vinegar collected from (A) the internal combustion furnace cover and (B) chimney are discussed separately. The total rice husk vinegar weight was 13.13-14.08 kg with cooling water but only 7.23 kg without cooling water. The pH value and acidity ranges were 3.1-3.6 and 5.9%-8.3%, respectively. The tar content was 1.3-3.9 but was 6.1 in the vinegar obtained from the chimney without cooling water.
