Study of Pressure Drop in the 2D Spouted Bed with Conical Base of Binary Particle Mixtures: Effects of Particle Size and Density
In this study, the pressure drop for the binary mixtures of particles differing in size and density in a pseudo-2D spouted bed was experimentally studied. A binary mixture of solid particles including sand, Gypsum, and polyurethane was used in the experimental setup. Effects of static bed height, cone angle, particles diameter, and a particles weight fraction on the bed pressure drop were e...

متن کاملApplicability of the spouting regime for drying of biomass wastes in conical spouted beds with a draft tube
The operating conditions in spouted bed regime of uniform beds consisting of different biomass wastes dry and wet have been studied to determine the applicability of conical spouted beds with a draft tube in the drying of biomass wastes. This experimental study has been carried out at room temperature and the effect of the solid humidity on the stability of beds of biomass wastes has been deter...
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 کاملPressure Drop in Liquid-Solid Circulating Fluidized Beds
An experiment was conducted to obtain data of pressure drop in riser tubes of liquid-solid circulating fluidized beds. In the experiment, 2 kinds of riser tube having a diameter of 24mm and 36mm were used. Tested particles were of glass and ceramics, and their diameter range was from 2.10 to 4.95mm. Water at ambient conditions was used as the fluidizing fluid. Pressure drop in riser tubes was m...
