Limestone Attrition during Fluidized Bed Calcium Looping Cycles for Co2 Capture: the Effect of So2
Attrition of six different limestones was studied during calcium looping cycles for CO2 capture in a lab-scale fluidized bed apparatus. The tests were carried out under realistic conditions representative of a process with calcination in an oxy-firing environment. The focus of the activity was to investigate the effect of the presence of SO2 both in the calcination and in the carbonation stages...
متن کاملHydrodynamics of a Gas-Solid Fluidized Bed at Elevated Temperatures Using the Radioactive Particle Tracking Technique
Effect of temperature on hydrodynamics of bubbling gas-solid fluidized beds was investigated. Experiments were carried out in the range of 25-600 ºC and different superficial gas velocities in the range of 0.17-0.78 m/s with sand particles. Time-position trajectory of particles was obtained by radioactive particle tracking technique. These data were used for determination of mean velocitie...
متن کاملFluidized Bed Desulfurization using Lime Obtained after Slow Calcination of Limestone Particles
In this work we have tested the fluidized bed desulfurization performance of lime particles obtained by means of a proprietary limestone slow calcination pre-treatment technique. This performance was compared to that of the parent untreated limestone particles. The occurrence of particle fragmentation and attrition during the fluidized bed operation was also investigated with a specific test pr...
متن کاملBubble formation on a single orifice in a gas solid fluidized bed using digital image analysis
Digital Image Analysis (DIA) has been employed to characterize the time evolution of a bubble injected from a single orifice into a pseudo 2-dimansional gas-solid fluidized bed. The injected bubble diameter increased with the square root of time before detachment. During bubble free flight in the bed, its diameter remains approximately constant. The center of mass of the bubble increases with t...
متن کاملCfd Analysis of Circulating Fluidized Bed Combustion
In this paper computational analysis of circulating fluidized bed combustion using the fluent software is analysed. This work is concerned about gas–solid two-phase mixtures flowing upwards through the fast beds. The procedures studied are applicable to all types of fluidized-bed boilers. The type of information resulting from various ways of analyzing the pressure and temperature in fluidized ...
