Effects of rapid heat transfer using a fluidized bed on the heat-treating response of Al-Si-Mg alloys (both unmodified and Sr modified) were investigated. The heating rate in the fluidized bed is greater than in conventional air convective furnaces. Particle size analyses of eutectic Si showed that the high heating rate during fluidized bed solution heat treatment causes faster fragmentation an...

Introduction Understanding the jetting phenomena near the gas distributor plate in a fluidized bed is important to gassolids mixing, heat and mass transfer, and erosion on any bed internals, which can all affect the performance of the bed. Moreover, acoustic vibration in a fluidized bed can be used to enhance the fluidization quality of particulate matter. Visualizing the jetting structure usin...

In this work, the techno-economic and exergy analyses of two gasification technologies with integration into heat power combined cycles are presented: i). Circulating fluidized bed (CFB) ii). Dual (DFB) systems. As feedstock, lignocellulosic biomass (sugarcane bagasse, SCB) was considered . The process fluidized-bed systems (circulating dual bed) syngas conversion were performed using Aspen Plu...

Rice is the main food in Indonesia. drying by using traditional method directly under sun light can require a long time to complete. The aim of this study investigate appropriate kinetics modeling rice with applied fluidized bed dryer. A 2-cm thickness has been dried at various temperatures (50℃, 60℃, and 70℃) air velocity 10 m/s from hot dryer obtained pyrolysis process. selected based on agre...
