Fixed (slow-moving) bed updraft gasification of agricultural residues
2006 (English)Conference paper (Refereed)
A laboratory-scale countercurrent fixed-bed gasifier has been designed and constructed to produce datafor process modelling and to compare the gasification characteristics of several biomasses. Densified woodybiomass, birch, in form of pellets with a diameter of 8 mm and a length between 5 and 15 mm has been used as a rawmaterial for batch autothermal gasification using air as an oxidation agent. The main objectives were to study theeffect of the treatment conditions on the distribution of the products and the composition of product gas to establishthe suitability of the gasifier to produce combustible gas with sufficiently high calorific value. The influence of theair flow rates on the composition of the producer gas has been studied. The amount of the biomass used in theexperiments was varied between 1 and 4 kg and the flow rate of the oxidation agent, air, was varied from 1,1 to 2,6m3/h.
