Performance Improvements Of A Westinghouse W-171 Gas Turbine By Coating Axial Compressor Blading
Gas turbine performance and efficiency is of increasing interest with the rising cost of energy. The axial compressor of a gas turbine requires 70% of it’s generated horsepower for operation, which makes the compressor an ideal place to develop efficiency improvements. By using an iron-aluminide intermetallic coating on the compressor blading of a gas turbine, it is possible to reduce blade surface friction; thus increasing efficiency, performance and reducing wear. This type of coating was used to increase the usable horsepower of a W-171 gas turbine in the Brownsville, Texas, Union Carbide Plant more than 10%.
