Parameters affecting the Fluidized bed performance: A review
Journal Title: REST Journal on Emerging trends in Modelling and Manufacturing - Year 2017, Vol 3, Issue 1
Abstract
Fluidized bed technology has been used in several fields since many years and it is one of the most popular one used in drying solid particles or granules. Fluidised bed drying is the most extensively used method for drying particles or granules majorly in pharmaceutical and food industries. The paper consists of detailed study of fluidised bed technology which includes classification of fluidized bed, fluidized bed combustion and heat transfer in the same. Out of several applications of fluidised bed technology – mentioned further - more emphasis is given on the fluidized bed dryer since it is one of the most beneficial and efficient of the dryers used in the industries due to the phenomenon of direct contact between the fluid and the particles. The controlling parameters regarding the same are mentioned and elaborated precisely. Our study depicts that the fluid-to particle type of heat transfer has been accentuated by the researchers while on the other hand, wall-to-fluid type of heat transfer has been least focused on. It has been found that the parameters like temperature and humidity affect the evaporation rate of the moisture from the particles and the velocity as well as the flow rate of air account for heat and mass transfer.
