E10 FILTRATION: ITS USE IN GAS TURBINE AIR FILTERS AND THE INFLUENCE OF PULSING ON PERFORMANCE

摘要

This paper reports the results of a field trial and active test cell challenging of ISO standard EN1822:2009 E10 grade gas turbine (GT) air intake filter cartridges that were designed to assess the effectiveness of pulsing in an urban location. The field trial took place on an operating gas turbine with filters tested and graded as E10 without pulsing. The test cell was a specially constructed mobile miniature filter house with pulsing capability. Statistical data for ambient environmental conditions and pressure drop at both the filter house and the test cell were recorded. The paper aims to show that current E10 technology is the ideal solution for almost all gas turbine installations as it represents the best compromise for perfect filtration. Included in the current work are product justification, trial site data, portable pulse test cell data, independent standard testing, internal product testing and post usage media analysis.
