Fluidized bed combustion of solid organic wastes and low-grade coals: research and modeling Borodulya, V. A. <'I rrl. PIW. /,tr. C'orlf Fhid. Bed Con~hmt.. 1995. 13. ( 2). Y35-Y42. Studies were carried out to study devolatilization and combustion of single spherical particles of wood. hydrolytic lignin from ethanol production, leather processing wastewater sludge. and low-grade Belarus brown coals in a fluidized hed of sand. A two-phase model of hiowaste fluidized bed combustion i\ proptrsed. The model accounts for combustion of both volatiles and char in the hed and in the freeboard. The characteristics of devolatilization and char combustionderived from the experiments are used as parameter\ of the proposed model.
