Evaluasi Kinerja Gasifier Up-draft Dengan Umpan Limbah Biomassa Kayu Mahoni Dari Industri Mebel

Abstract

Wood waste from furniture industries was gasified using up-draft gasifier type. The type of wood was used is mahogany. Operation of the gasifier is batch model  with wood waste concumption per batch is 4 kg, 7 kg and 9 kg.  Equivalent ratio of air used is 24,73%, 14,13% and  10,99%.  The mahogany have properties of ultimate analysis  is 13,8%-wt moisture content, 65,8%-wt volatile matter, 48,7%-wt fixed carbon and 2,24%-ash. Temperature profile of gasifier observed during operation as a time function.  The gasifier also integrated with scrubber buble column and water as a solvent to minimize tar in the producer gas. The scrubber buble column was used has efficiency removal is 57,41%.
