Gasification Characteristics Of An Updraft Double Gas Outlet Gasifier Using Rubber Wood As A Fuel

Gasification system is one example of the utilization of biomass for energy. It converts solid fuel into gasification combustible gas like CO, H2, and CH4 because of the reaction occurring in the gasification reactor to be used later as an energy source. This research will test the updraft gasification system by modifying it into a system with two outputs, namely in the area of the gasifier as a conventional system and the area under the gasifier in an effort to reduce the tar content in gas can burn. This study uses a blower with a flow rate of 108 lpm and the results of testing will be compared with the conventional system in order to get the characteristics of the test. The results of these tests indicate that the gas could be burned out of both pieces of pipe flow with LHV value of each is 4.470 MJ/m3 for the top and bottom area of 4.082 MJ/m3 for which the fuel gas composition coming out of the upper area and below the percentage value that is approximately the same for CO 22.695% to 20.805%, H2 gas of 9.835% versus 9.05%, and CH4 gas at 2.66% versus 2.38%. While the value obtained from the conventional system is 4.473 MJ/m3 with gas composition of CO, H2, and CH4 at 21.92%, 10.51%, and 2.74% respectively. Cold gas efficiency for systems with two output areas has a higher value than the conventional system is 53.087% to 46.519%. Keywords- Gasification, Rubber Wood, Double Gas Outlet and Syngas
