Equivalence ratio is parameters for control gasification performance. The purpose of this study is to evaluate gasification rubber wood in conventional updraft gasifier. In this study, the equivalence ratio is varied from 0.21-0.31 according to obtain temperature distribution, gas composition, LHV of the gas, cold gas efficiency and tar content produced. The highest of LHV the gas reachs of 4.2 MJ/m3 with cold gas efficiency of 75% and tar content of 140 g/m3 at equivalence ratio of 0.31. ER -
