Abstract
This study investigates the standards, design principles, and localization process of a pulse air inlet filter for gas turbines, focusing on a successful case at Bushehr Petrochemical Complex. The main objective was to develop a domestically manufactured filter with performance equivalent to the Camfil reference while reducing operational costs. Localization involved extracting the technical specifications of the original filter and applying an electrospun nanofiber coating onto commercial filter media. Experimental results showed that the localized filter achieved the F9 filtration class while reducing total pressure drop from 422 Pa to 121 Pa—approximately a 71% improvement in airflow resistance. This reduction directly decreases power consumption and enhances turbine efficiency. The nanofiber layer improved surface filtration, preventing deep clogging within the media. The localized filter demonstrated stable, economical, and reliable performance, offering lower manufacturing costs and easier accessibility, making it a suitable replacement for the original imported unit.
