Abstract

Development on fluidized bed gasification of biomass has been initiated by
Yayasan Dian Desa collaboration with NEDO (New Energy and Industrial
Technology Development Organization of Japan) starting from small scale
(2000–2003), bench–scale tests (2004–2005) and pilot–plant (2006–2009). Since
2006, a cooperative research and development on fluidized–bed gasification of
biomass established and agreed between the BPP Teknologi, Yayasan Dian
Desa and NEDO to investigate the influence of the air factor on other gasifier
operation parameters: bed temperature, gas calorific value and gasifier cold
efficiency. The experiments were carried out with the following kinds of biomass:
rice husk, sawdust, sugarcane bagasse and spent coffee grounds. The
relationship between the gasifier cold efficiency and air factor shows that the
curves for rice husk and sawdust have a maximum; for bagasse the relationship
is decreasing because of intensive elutriation; for spent coffee grounds due to
feeder limitations, it was not possible to feed the biomass flow corresponding to
air factor values greater than 0.2. The low efficiency values are a consequence of
the lack of thermal insulation in the freeboard zone.
