Theses and Dissertations
The Energy and Environmental Research Center is working with EPRI and a consortium of companies in partnership with DOE to determine factors causing sticky ash to blind or bridge hot-gas cleanup filters. In this study, bright and dull lithotypes were separated from bituminous, subbituminous and lignitic coals to determine physical and chemical properties that may lead to the formation of different charforms, and consequently, fine and sticky ash that is problematic in coal-fired combustion systems.
Proximate and ultimate, maceral, and energy dispersive X-ray fluorescence (EDXRF) analyses were used to characterize each lithotype. A bench-scale pressurized fluidized-bed reactor (PFBR) was used …
