Phosphorus-Rich Ash from Poultry Manure Combustion in a Fluidized Bed Reactor

The aim of this study was to examine the physico-chemical and phase characteristics ash obtained in process combustion Polish poultry manure a laboratory reactor with bubbling fluidized bed. Three experiments, differing grain size morphology raw material, method its dosing type bed, were carried out. contents main chemical components trace elements samples determined using WDXRF, composition examined through XRD method. grains given micro-area SEM/EDS also investigated. highest concentration phosphorus (from 28.07% wt. 29.71% as P2O5 equivalent), proportion amorphous substance 56.7% 59.0% wt.) lowest content unburned organic (LOI from 6.42% 9.16%) (i.e., best efficiency), for experiment which starting bed quartz sand fed form pellets. It has been calculated that case, contains more than half phosphorus. carrying out significant impact on and, consequently, availability
