Abstract:
Small scale biomass gasification is one of the most interesting option for lignocellulosic biomass and wastes. Small scale systems are attractive for farmers since the low energy density of biomass fuels makes transportation a relevant cost factor: valorisation of agricultural residues is gaining particular interest as they are considered "no land using" and potentially low cost biomass. CREAR /RE-CORD installed, in an experimental area located South of Florence, an innovative gasification system for multi-fuel applications developed by Indian Institute of Science (IISc), Bangalore. The innovative open top downdraft double fire reactor configuration is capable of processing agricultural and forestry residues, and the cooling and cleaning system makes the gas fit as a fuel for a 70 kWe spark ignition engine. The paper highlights the outcome of a series of test with pruning residues as a feedstock, conveniently pre-treated in order to address low density and high ash content issues. Gas composition and quality of producer gas measured on line indicated very low level of contaminants in the gas and cold gas efficiency was found to be in excess of 75 %. Engine was tested and was found to respond to varying load excellently. Peak load of 70 kWe was achieved using a resistive load bank.
