Experimental study on the temperature distribution in fluidised beds

Heat management problems often prevail in reactors when highly exothermic chemical reactions occur. In these situations, fluidised bed are preferred due to their excellent heat transfer capabilities. However, the design, scale-up and operation of is still challenging complex hydrodynamics. To gain a better understanding on transport reactors, degree temperature non-uniformity for several fluidisation regimes pseudo-2D was quantified using Infra-Red Thermography. The Probability Density Functions were obtained from whole-field data, which standard deviation, i.e. width distribution, skewness, dominant temperatures distribution. Based loss data bubble frequencies, deviation skewness good indicators solids mixing behaviour studied regimes. addition, effect spout velocity thermal characteristics studied.
