英文摘要	The hydrodynamics of the gas-solid two-phase flow and vaporization of the water phase in an integral multijet spout-fluidized bed (IMJSFB) and spouted beds with spherical longitudinal vortex generators (LVGs) and an integral swirling blade nozzle (ISBN) was numerically simulated. These three novel strengthening components are adopted for the strengthening of the radial mixing of particles, promoting the uniformity of the flow field velocity distribution, and increasing the water vaporization rate. The simulation results show that the three novel strengthening components can promote the uniformity of fluid flow velocity distribution in beds, and the promotion effect is arranged in descending order as follows: LVGs > swirling blades > multijet. In the case of water vaporization, the LVGs, swirling blade, and multijet mainly promote the vaporization of water near the generators, in the spout zone, and the zone near the side nozzles, respectively. Among them, the swirling blade contributes the most to water vaporization, followed by the multijet and then LVGs. In addition, when the gas inlet velocity and temperature are 11.2 m/s and 520 K, respectively, water vaporization is most obviously boosted.
