This paper presents the results obtained from RDF and sawdust combustion in a pilot scale vortexing fluidized bed combustor (VFBC). Flue gas recirculation (FGR) combustion mode was employed. The effects of operating parameters such as bed temperature, excess oxygen ratio, and in-bed...

Flow characteristics and heat transfer performances of rectangular dimpled channels with secondary protrusions are numerically analyzed and compared in this research work. The special arrangement is a conventional dimpled cavity with a small-size secondary protrusion placed upstream of the...
