1. Formation of Polychlorinated Dibenzo-p-dioxins and furans in incinerators:
laboratory and modeling studies of formation rates, analysis of incinerator measurements, review of hazardous and medical waste incinerators. The laboratory studies employ fixed bed and aerosol flow reactors. Combustion studies are carried out in a spouted bed combustor. Analyses are performed by GC/MS.
Objective: To gain an improved understanding of dioxin formation in combustors and to delineate control strategies for these compounds.
2. Spouted bed combustion of gaseous, liquid, and solid fuels: Measurements of DRE (destruction and removal efficiency), CE (combustion efficiency) and NOx relationship of these parameters to bed hydrodynamics and geometry. Comparison of flame combustion to nonflame (but high temperature) mode; characterization of heterogeneous and mass transfer effects.
Objective: To characterize fundamental and applied performance parameters of spouted beds for waste destruction applications.
Current research group consists of one postdoctoral fellows, two Ph.D., two M.S. students and two undergraduate students.
