Operating Results With Gas Turbines of Large Output

Operational figures of some Brown Boveri gas-turbine installations classed according to the fuel burned: oil, blast furnace gas, natural gas. Corrosion and contamination of gas-turbine blades, laboratory and pilot tests, general considerations, fuel oils obtainable, their ash content and composition, and their suitability for use in gas turbines. Effect of the ash content and ash composition of liquid fuels, and of the dust content and dust composition of gaseous fuels on the life of the blading material. Drop in output and efficiency with time. Reduction of the rate of contamination of the blades by additives in the fuel. Experience with natural gas-fired gas turbines. Plant maintenance costs.
