Paper 9: Combustion Aspects of Industrially Applied Aero Gas Turbines

This paper concentrates on the combustion experience gained by the application of the Rolls-Royce Avon aero gas turbine to industrial usage and each of the following subjects is considered in detail. A brief summary of the design philosophy which has dictated the configuration of the basic aero combustion equipment. The particular implications of industrial operation as this affects the combustion system. This includes the effect of different fuels and operation for long periods in a ground level environment. The operational problems experienced to date with the basic aero equipment and the design and development work undertaken to overcome them. These problems comprise frettage, flare distortion, smoke output, starting, corrosion and combustion stability. The design and development of an improved system, now under way, which will be capable of satisfactory operation with a wide range of liquid or gaseous fuels without component change. The use of steam injection into the combustion system as a means of improving overall cycle efficiency. Consideration of the range of industrial fuels available, from diluted gases to distillate and residual oils, and their suitability for gas turbine usage. Future trends in combustion technology.
