Fundamental Particle Fluidization Mechanism and Handling of Fine Particles in a Rotating Fluidized Bed
Fluidized bed has many advantages such as high heat and mass transfer rates, temperature homogeneity and good mixing property. However, conventional fluidized bed has some limitations; operation at high gas velocity leads to slugging and there exists minimum particle size for the uniform fluidization. Recently, a rotating fluidized bed (RFB) has attracted special interest, since it has a possib...
متن کاملHydrodynamics And Heat Transfer Characteristics Of Draft Tube Spouted Bed Roasting Of Groundnuts (Arachis Hypogeae)
The hydrodynamic characteristics of flow regime were studied employing different draft tubes during the spouted bed roasting of groundnuts and the dimensionless parameters were employed for predicting the flow regime. The estimated Reynolds's number (Re) under the turbulent convection regime was ≈ 8399. The size of the draft tubes employed ranged from 0.175 to 0.375 m length and 0.065 m diamete...
متن کاملInvestigation of a Cold Model of Internally Circulating Fluidized Bed with Draft Tube to be used as a two-Zone Fluidized Bed Reactor
In this research, a cold model of internally circulating fluidized bed is investigated. The aim is to find the effects of some of the operating parameters on the performance of the reactor. Experiments were carried out in a glass column (30 mm i.d. and 25 cm height) with a centrally located draft tube (11 mm i.d. and 5 or 7 cm height). The bed was loaded with white silica particles (dp = 0.15 -...
متن کاملPrediction of Minimum Spout Velocity and Moisture Distribution of Ammonium Perchlorate Particles in a Spouted Bed Dryer
Ammonium perchlorate particles have been dried in a laboratory spouted bed dryer (screen-bottomed type) which is categorized as a fluidized bed dryer. The solid particles obtained in this process of drying were semi-porous and known as the group D of Geldart classification. The variations of moisture content with resident time, the effects of bed height on the pressure dro...
متن کاملIntermittent Drying of Beans in a Spouted Bed
Carioca beans are a highly nutritious grain, in terms of the amount of protein, iron and potassium as well as carbohydrates and fiber and as a source of vitamins. The moisture content of recently picked beans is too high for good preservation and storage, resulting in the need for drying before packaging. In this work, the drying of Carioca beans in a laboratory scale spouted bed under intermit...
