4. Layer Formation on Bed Particles during Fluidized Bed Combustion and Gasification of Woody Biomass
Abstract : Although more than a hundred papers dealing with the agglomeration problem in combustion and gasification of biomass can be found in the literature, very few studies focusing on the bed particle layer formation process in fluidized bed combustion (FBC) and fluidized bed gasification (FBG) can be found. With increased knowledge of the bed particle layer formation process — i. READ MORE

5. Characterization of Ceramic Raw Minerals in Uganda for Production of Electrical Porcelain Insulators
Abstract : In this work an extended literature survey on ceramics and porcelains in particular, has been documented. Samples from two Ugandan deposits of each feldspar and quartz were characterised by means of X-ray diffraction, thermal analysis, chemical analysis and scanning electron microscopy and found to possess requisite properties for making electro porcelain insulators.
