【Abstract】 Heat transfer of liquid evaporation was studied in a recirculating three-phase fluidized bed in which an inert gas serving as "carrying gas" was introduced. The gas velocities, particle sizes, particle densities and particle concentrations in the liquid were examined. Heat fluxes were measured as well. Significant enhancement in heat transfer was resulted when an inert gas and solid particles were introduced into the flow boiling liquid. Scaling mitigation was to be expected in the process.更多还原
