Tittel
Accelerated Deterioration by Saltwater Ingestion in Gas Turbine Intake Air Filters
Sammendrag
There is currently no international standard for evaluating and documenting the performance of the complete gas turbine intake air system in offshore applications. Several suppliers document the performance of their filters in accordance with applicable Heating, Ventilation, and Air Conditioning (HVAC) air-filtration standards for general ventilation. These standards fail to address the offshore-specific challenges related to salt removal and moist and wet operation and cannot be used to accurately predict operational performance or life. It is therefore desirable to develop suitable test methods and standards that can be used to better predict operational performance and life before filters and complete inlet air systems are put into operation offshore. An experimental test rig has been built in the laboratory at the Norwegian University of Science and Technology (NTNU) in order to increase understanding of the fundamentals related to gas turbine inlet air filtration. This paper presents the results from an experimental test program where the test rig was used to evaluate the effect of accelerated deterioration of high-efficiency filter elements for gas turbine inlet air filtration. High-efficiency filter elements from different suppliers were deteriorated by ingesting a saltwater solution. The performance of the filters exposed to accelerated deterioration was evaluated for different levels of contamination and compared to the performance of filter elements that have accumulated comparable amounts of contaminants in offshore operation.
