Problems Associated With Cold Weather Operation of Gas Turbines

Abstract

The operation of gas turbines during conditions of extreme cold weather can present a variety of problems. Foremost among these problems is the potential for snow and ice buildup in the air intake system which can cause restrictions or interruptions in operation and possible ingestion damage to the axial compressor section of the gas turbine. Other cold weather operating problems include cold lubricating oil and oil system blockages following periods of shutdown. Major maintenance on the equipment becomes very difficult, if not impossible, during conditions of extremely cold weather unless the work can be carried out in an adequately heated building. This paper expands on these problems and others and outlines methods which have been developed to deal with them. Its content could be of benefit to design engineers engaged in preparing specifications for gas turbine equipment to be used in cold climates.
