CO-GASIFIKASI SISTEM DOWNDRAFT (DITINJAU DARI PENGARUH LAJU ALIR UDARA BAHAN BAKAR TERHADAP PRODUK SYNGAS)

Abstract

The potential of coal is large enough in Indonesia spur to do the increased utilization, one of them in the form of gasifikasi.Gasifikasi coal is one form of utilization of natural resources that continue to be developed because of its abundant potential.However, the process of gasification with coal fuel generates a lot of CO2 emissions and NOx and SOx pollutants. Therefore, to reduce the amount of emissions produced is a combination of fuel in the gasification process by utilizing biomass (coconut shell and wood waste). Mixing coal and biomass is expected to increase the calorific value and reduce the emissions produced. This research was conducted to get the product of syngas with good flame in fire tube test.. In this research, the changed variable is air flow rate with valve opening with 60% : 9.11 m3/hr, 70% : 10.02 m3/hr, 80% : 10.93 m3/hr, 90% : 11.48 m3/hr, 100% : 12.37 m3/hr and comparation of fuel composition used and time operating as fixed variable. Based on the research, it is known that air flow rate of fuel that have good quality with caloric and best flame on9,11 m3/hr which have red characteristic with stable.
