The main advantage of a fluidized bed is its capability in excellent gas-fuel mixing. However, due to the lacks of gas radial momentum, its lateral mixing of gas-solid is not adequate. Therefore, this research is focused on fluidized bed hydrodynamics enhancement using the modified gas distributor plate design. For getting an optimum fluidized bed hydrodynamics prediction, three different class...

The role of two oxygen sources, and water vapor, in the initiation KCl-induced high-temperature corrosion was addressed by studying high-alloyed commercial materials at 550 °C. differentiation between sources implemented with 18O-enriched 16O2. Based on results, solid-solid reaction KCl(s) protective oxide alloy surface appeared to be more responsible for than gas-solid KCl(g) oxide. Water invo...

Evaporation kinetics of fused silica were measured up to ≈3000K using CO(2) laser heating, while solid-gas phase chemistry of silica was assessed with hydrogen, air, and nitrogen. Enhanced evaporation in hydrogen was attributed to an additional reduction pathway, while oxidizing conditions pushed the reaction backwards. The observed mass transport limitations supported use of a near-equilibrium...
