Experimental Study of Attrition in the Spouted Bed and Spout-Fluid Bed with a Draft Tube [PDF]
Iranian Journal of Chemical Engineering, 2020 The attrition of 300 µm natural zeolite particles was studied in a laboratory scale draft tube spouted bed (DTSB) and spout-fluid bed (DTSFB). It has been shown that the attrition rate decreases with time and reaches to an almost constant value.

Encapsulation of Oxidizers: Efficient Method by Spout-fluid Bed
Journal of Aerospace Technology and Management, 2020 In composite solid propellants, the oxidizer in the form of particles is embedded in a polymeric matrix. In general, these oxidizers consist in inorganic salts that are hygroscopic, chemically incompatible or sensitive to friction or impact, so that ...

An investigation of MSW gasification in a spout-fluid bed reactor
Fuel Processing Technology, 2008 Abstract This paper presents the experimental results of MSW gasification in a spout-fluid bed reactor. Municipal solid waste (MSW) modeled based on compositions of Bangkok waste transfer station “On-nuch” was used as the fuel. Three scenarios were investigated in this study. In the base case scenario, only primary air of equivalence ratios (ER) 0.35,

Evaluation of different mathematical models in the CFD-DEM simulation of conical spouted bed fluid dynamics [PDF]
Chemical Industry and Chemical Engineering Quarterly, 2021 The input parameters, empirical, and semi-empirical models significantly influence the responses obtained by CFD-DEM simulations. In this work, the effects of three turbulence models, three conditions of the particle rotation, and five drag models, on ...
