PENGARUH LUAS LUBANG INPUT UDARA SEKUNDER TERHADAP KINERJA TUNGKU GASIFIKASI BIOMASSA DENGAN ALIRAN UDARA ALAMI

Abstract

Indonesia is one of countries with amount of biomass is abundant. In order to keep availability of energy in the future, we have to do biomass utilization to replace fossil energy. One of utilization that can be done is make them as fuel of gasification stove for human needs. The objective of research is to understand about the influence of secondary air area toward performance of biomass gasification stove with nature air flows. Biomass that used for this research is pine wood which cut with size of approximately 2 x 2 cm. The treatment of this research is modify of secondary air area, which is 6 hole (4,68 cm2), 9 hole (7,02 cm2), 12 hole (9,36 cm2), 18 hole (14,04 cm2), and 24 hole (18,72 cm2). Analyzing of stove performance is based on primary tube temperature, secondary tube temperature, fire temperature, and energy efficiency of its convertion. The best performance of gasification stove is obtained at 12 hole (9,36 cm2) and produce burning time up to 52,63 minute/kg with efficiency value is 22.82% and fire temperature is 692.2°C
