In this study, the characteristics and the combustion performance of syngas produced from biomass waste especially wood waste gasification were investigated in term of gas composition and emission released in a downdraft and fluidized bed gasifiers. The flame length, gas characteristic and formation were determined beside energy level produced from both gasifier systems. Syngas generated from wood waste were combusted in a gas burner at temperature 762°C and 505°C for the cases of downdraft and fluidized bed respectively. As results from combustion, NO X , SO 2 and CO produced 56ppm, 1ppm and 33ppm respectively. Meanwhile, the gas compositions from the combustion were about 0.04%, 1.4%, 0.5%, 97.9% and 0.1% for H 2 , N 2 , CH 4 , CO, and CO 2 respectively. In this study the flame length of the combusted wood wastes in a downdraft showed unstable flame (oval shape) with the longest flame of 12.5 cm if compared to fluidized bed at 5.4 cm which was more stable in a rectangular shape.

Introduction Malaysia has a drastic growth in population and high energy demand. Having dependent mainly on oil and gas for half a century, Malaysia has started to realize the importance to adopt renewable energy. The government initiative to encourage researchers to study and develop on any potential material that could contribute for energy supplied and secured for future generation used [1]. Mekhilef et al., [2] discussed that fossil fuels as a natural resources energy will not sustain any more soon because of environmental impacts and depletion of the reserves. Asadullah [3] shared that there are many ways of generating electricity using the heat which produced in combustion, including the steam turbine, the reciprocating steam engine, Stirling engines, indirect fired gas turbines and direct fired gas turbines. Ahmad et al., [4] stated that Malaysian Government has taken continuous effort to encourage researchers to focus on the development of Renewable Energy through own  Corresponding author.
