Investigation of Performance of High Velocity Air Intake Wave-plate Separators for Marine Gas Turbines

摘要

Due to the advantages of great power, small size and light weight, the application of gas turbines in marine power facilities has increased a lot over time. Concerning the factors of off-shore operating environments which include the huge air intake quantity, the massive mist marine circumstance and the precious vessel available capacity, this paper combined experimental study with numerical simulation to investigate the performance of a type of new air intake wave-plate separator which can be applied under high intake velocity conditions. The total pressure drop was measured in a small wind tunnel with the inlet velocities of the separators ranging from 1.0 to 15.0 m/s. The resistance characteristics of high velocity wave-plate separators were simulated under the same velocity range described above. The separation efficiencies of high velocity wave-plate separators were simulated under the inlet velocity of 14.0 m/s, and the liquid diameters were 5μm, 10μm, 15μm and 20μm respectively. By analyzing the results of experiments and simulations, this paper draws the conclusion that high velocity wave-plate separators can keep high separation efficiencies and acceptable total pressure drop under high inlet velocities.
