Abstract: The basic characteristic of the rough particle flow in the cyclone is 100% of collection efficiency. This phenomenon occurs because as soon as particles enter the equipment they go to the cyclone wall and move downward to the hopper. In this case, the gas-particle heat transfer occurs basically close to cyclone wall, with same concurrent movement. Due to this fluid dynamics description, it is proposed in this paper a model to gas-particle heat transfer in cyclones based on concurrent moving bed model. The model results are compared with the ones obtained experimentally in two Lapple cyclones, using two different particles with different size. It was observed a good agreement between experimental and model results of outlet air and particle temperatures.
