Abstract
Biomass is one of the most important potential sources of renewable energy in Malaysia. Resources are available from palm oil plantations, forestry and wood industry, rice husk and several other agricultural sources and agro-industries. This paper will present an analysis of gas concentration under various parameters in a biomass gasifier. An experimental investigation of a suction downdraft gasifier is carried out using furniture wood. The producer gas is induced from the gasifier using an ejector sytem connected to air compressor. The gas generated passes into a swirl burner where the gas burns at high temperature. Gas sample was taken before it passes to swirl bumer and gas analysis was conducted using Gas Chromatograph. The objective of this project is to determine which ejector would results in highest calorific value of producer gas and to study the effect of equivalence ratio on the calorific value of the producer gas. The gas analysis is used as a basis to determine the calorific value of the producer gas. This final year project has achieved its objective that is 2mm ejector was found to be better than 4mm. The low heating value of producer gas is directly proportional with the equivalence ratio. Equivalence ratio in this project same with the previous study done by Muharif,2006 which is in the range of 0.19-0.43. The low heating value of producer gas obtained from this project is in the range 1000 - 2000 kJ/Nm which is much lower than theoretical value 4000 5000 kJ/Nm. This may be due to the size of suction gasifier which it consume low biomass and the energy produced also low.
