Chemical looping gasification (CLG) is a novel dual-fluidized bed technology that allows for the production of high-calorific syngas from various solid feedstocks (e.g., biomass). Solid circulation between two coupled fluidized reactors, serving purpose heat and oxygen transport, key parameter CLG technology, making system hydrodynamics backbone process. This study serves to provide holistic in...

Fluidized bed processing is a relatively novel method for coating metal substrates. A detailed study was carried out into surface property and in micro-structure changes induced by fluidized bed processing. In particular, fluidized bed processing of AA 6082 T6 aluminum alloy components using alumina Al2O3 powder was investigated. Firstly, the build up of Al2O3 films was studied and characterize...

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 mechanism of vibration energy transfer in a vibrating fluidized bed (VFB) is reported in this paper. A series of sensors was employed to simultaneously detect pressure wave propagation signals at different positions at various heights in the fluidized bed. The mechanism of vibration energy transfer in an VFB is found by wave propagation. The pressure wave was produced from a vibrating base ...

This study aimed to determine the effect of rice husk fluidization and variation in equivalence ratio bubbling fluidized bed gasifiers without sand materials. It also improve quality by reducing diameter husks. Therefore, bulk density increases, whereas voidage decreases, both which are main parameters for improving solid particles. Experiments were carried out at a velocity 0.82 m/s, varying e...

drying properties of high moisture potato slices with initial moisture content of about 4.06 (db) under thin layer fixed, semi fluidized and fluidized bed conditions were studied. drying air temperatures of 40, 50, 60 and 70°c were applied in experiments using a laboratory fluidized bed convective dryer. in order to predict the drying behavior of potato slices, seven thin layer drying models we...
