This paper presents a numerical study of gas-solid two-phase flow and water vaporization in a 3D powder-particle spouted bed (PPSB) by means of the combined approach of the Eulerian-Eulerian two-fluid model (TFM) and kinetic theory of granular flows (KTGF). The simulation shows that the gas temperature in the injection area is higher than water and particles, and the three-phase temperatures in other areas are similar. The water vaporization rate is higher at the junction of the injection area
