The paper gives results of an experimental study of cyclone efficiency and pressure drop at temperatures up to 700C and pressures up to 25 atm. The cyclone efficiency was found to decrease at high temperature and increase at high pressure for a constant inlet velocity. Available theoretical models could not predict the observed effects of high temperature and high pressure on collection efficiency. Pressure-drop models predict the effects of temperature and pressure fairly well. Collection-efficiency data correlated well against Reynolds number and the square root of Stokes' number. This correlation accurately accounted for the effects of both temperature and pressure. These data are for a 2-in. diameter cyclone at relatively low velocities (less than 5 m/s). Data for a 6-in. cyclone of similar configuration and operating at 635 C, 700 kPa, and 36 m/s also agreed well with this correlation.
