    Two fluidized bed gasifier models has therefore been set up in order to evaluate the affects: one model which only considers the kinetics of a gasifier and a second model which includes both the kinetics and the hydrodynamic parameters for a bubbling fluidized bed. The kinetic model is .   The authors discuss flow through fixed beds, elutriation and entrainment, gas distributor and plenum design in fluidized beds, effect of internal tubes and baffles, general approaches to reactor design, applications for gasifiers and combustors, dilute phase pneumatic conveying, and applications for chemical production and processing.5/5(2).

    Providing comprehensive insight into the working principles of fluidized bed boilers and gasifiers, the book covers how the equipment works, the basic principles of thermodynamics and fluid mechanics, planning new projects and the trouble-shooting or operating of fluidized bed boilers or gasification plants. @article{osti_, title = {Mathematical modelling of fluidized bed coal gasifiers}, author = {Yan, H M and Heidenreich, C and Zhang, D K}, abstractNote = {A steady-state isothermal model has been developed to simulate performance of bubbling fluidized-bed coal gasifiers of various scales. Building on the two-phase fluidization theory, the model considers a comprehensive .

    Gas-solid fluidized bed dryers are used in a wide range of industrial applications. With applying computational fluid dynamic (CFD) techniques, hydrodynamics of a two-dimensional nonreactive gas-solid fluidized bed dryer was investigated. A multifluid Eulerian model incorporating the kinetic theory for solid particles was applied to simulate the unsteady state behavior of this Cited by: numerically simulation of fluidized bed coal gasifier. We have to analyze, design, and optimize the performance of fluidized bed devices which helps in the development of multidimensional combustors and gasifiers models. These multidimensional models will bridge the gap between sub-scale testing and the operation of fluidized bed furnaces by.
