Abstract The report gives results of a theoretical and experimental investigation of the effects of high temperatures and high pressures (HTPs) on fundamental particle collection mechanisms. It gives experimental results of inertial impaction, cyclone separation, Brownian diffusion, and electrical migration tests at HTPs. The inertial impaction tests showed that existing impaction models are adequate for HTP predictions. Practical problems (e.g., materials, seals, and particle adhesion) pose more difficulties than any fundamental variations from impaction theory. The cyclone tests showed that cyclone efficiency decreases at high temperature and increases at high pressure for a constant inlet velocity. Available theoretical models could not predict the observed effects of HTP on collection efficiency. An empirical correlation for predicting the cyclone cut diameter was derived. Existing pressure-drop models predict the effects of HTP fairly well. The Brownian diffusion tests showed no detectable effects of HTP. This result is consistent with predictions for the particle size used in the tests (dp > 0.5 micrometer). No useful high temperature data were obtained with the electrical migration apparatus.
