A simple model for prediction of solid collection efficiency of a gas–solid separator

A semiempirical model has been developed for the prediction of the grade efficiencies of a gas–solid cyclone for circulating fluidized bed (CFB) boilers. The model is based on the equilibrium orbit theory. Experiments were conducted in a large cyclone to gather data on grade efficiencies for model verification. The model gives a good agreement between predicted and experimental values of grade efficiencies.
