Gas Turbine Intake Systems: High Velocity Filtration for Marine GT Installations — Part 2 Available to Purchase

Following the development of a high velocity spray eliminator system for marine gas turbines, a sea trial has been completed on board a Royal Navy vessel, for back to back comparison with a unit of conventional design. This paper, will give a brief overview of the trial fit to HMS Coventry. It will then continue by presenting in detail the data obtained throughout the trial and showing the resulting comparisons between the new high velocity and conventional designs. The initial and final inspections of both engines will be presented and the appraisal by Rolls Royce, the engine design authority, will be discussed. Conclusions will be drawn detailing the suitability of the new high velocity design for use onboard RN vessels, to protect their gas turbine intakes. Design parameters for the intakes of the WR21 will be proposed to demonstrate the system’s potential benefits.
