EFFECT OF TEMPERATURE AND TYPE OF BIOMASS DURING THE PRODUCTION OF SOLID FUEL ASHES ON THEIR COMPOSITION AND PROPERTIES IN COMPARISON WITH COAL ASHES

Popis výsledku v původním jazyce

In this study, ashes were prepared by annealing the samples of selected types of solid fuels (biomass - corn cob, sunflower husk, waste from olives, hay pellets and rice husk, coal - brown and black, alternative fuel - paper sludge) at different temperatures (550 oC, 815 oC and 975 oC). Analyzes of ashes were performed to determine the effect of the type of ash and the preparation temperature on the composition and properties of the ashes. Based on the XRF results, the slagging/fouling indexes were used to study the effects of the type of ash and the ashing temperature on the ash fouling and slagging properties which were compared with the results of the measurement of ash fusion temperatures. The lowest temperatures show ashes from hay pellets and corn cobs at 550 oC when the deformation temperature (DT) is below 1000 oC. On the other hand, for ashes made from paper sludge at 550 oC, sunflower husks at 550 oC and rice husks at 550, 815 and 975 oC, the deformation temperature exceeds 1500 oC.
