| Abstract: | Experimental results for gas-solid separations in a 102 mm diameter conventional cyclone operated with air heated to temperatures between 300 K and 2 000 K, are presented. Overall and fractional collection efficiencies were measured for alumina and silica having particle sizes of 100% less than 44 μm and mass median diameters of 5.0 and 10.0 μm respectively. Inlet velocities ranged from three to 42 m/s and inlet dust loads were between 0.3 and 235 g/m3. The dust load had a strong influence on the collection efficiency and the loading effect was stronger at high temperatures. |
