Field Experience With Pulse-Jet Self-Cleaning Air Filtration on Gas Turbines in an Arctic Environment

This paper discusses the results of continuous duty operation of automatic self-cleaning air filtration systems on a gas turbine application during a winter season in a North Slope Alaska arctic environment where equipment is subjected to extremely low ambient temperatures, ice fog, and blowing snow. The effects of wind direction, temperature change, and filter installation configurations relative to filter performance are discussed. Recommendations for setup and operation of self-cleaning air filters in cold weather and arctic environments are presented.
