Abstract:

Industrial gasification of biomass often face fouling caused by the formation of deposits. Fouling can be particularly extensive when alternative biomass is gasified, with high concentrations of calcium, phosphorus, chlorine, sulphur and potassium. The good example of such awkward biomass is poultry feathers, which is successfully gasified in the robust 3.5 MWth fixed-bed updraft gasification plant in Olsztyn, Poland. The bottom ashes and fireside deposits, which are formed along the plant, were collected and analyzed by means of X-ray Fluorescence and X-ray Diffraction. The analysis revealed that bottom ash and deposits in gasifier consist more than 67 % of hydroxyapatite [Ca10(PO4)6(OH)2], the substitute of natural bones. In fact, different amount of hydroxyapatite is recognised in deposits collected from different apparatuses.
