Abstract:

The average concentration and particle size distribution of the dust passing the inlet air cleaner and entering a gas turbine powering the Overland Train was determined using model air cleaners which duplicate the performance of the main engine air cleaners. It was found that the main engine air cleaners reduced the dust concentration from an average ambient concentration of 4.7 mg.cu. ft. to an average passing concentration of 0.73 mg.cu.ft. Because of agglomeration, dust passing the air cleaner is apparently the same size as the dust entering, measured as discrete particles. If the effective particle size were measured the dust passing the air cleaner would be finer than the dust entering. Based on past Overland Train experience of short turbine life caused by dust ingestion, the STRATAPanel Air Cleaners installed on the Overland Train will significantly extend the life of the gas turbines.
