Experimental data on heat transfer between the inside wall a vertical tube and gas-liquid-minute solid particles multi-phase upflow in the tube were reported. At the present time, we need to overcome enormous difficulties before understanding the heat transfer characteristics in a gas-liquid-solid multi-phase flow system under high temperature and high pressure conditions such as in the preheater section of the coal liquefaction process. Hence, it is essential to collect data from the “cold model" experiments before obtaining data from “hot” experiments. The heat transfer coefficient data were obtained under the following conditions: tube diameter=27.0mm, gas velocity=15-300cm/s, liquid of slurry velocity=10-30cm/s, and solid concentration in slurry=0-60wt%. The following results were obtained: 1) When minute solid particles were mixed together, measured heat transfer coefficients were larger than those in the gas-liquid flow. 2) No difference in heat transfer coefficient between two kinds of minute glass spheres, having 30 and 100 μm in round size, were detectable under most of the experimental conditions studied. However, in the regions of comparatively high slurry velocities and high solid concentrations in slurry, larger heat transfer coefficients were obtained when the smaller particles were used. 3) An empirical correlation on the heat transfer coefficient for the gas-liquid and gas-liquid-solid multi-phase systems was proposed, which was found to fit the data within 40% in the froth regime of gas velocities above 150cm/s. |
