GAS TURBINES DURABILITY IN HARSH ENVIRONMENTS

LectureThe performance and durability of industrial gas turbines are strongly dependent on the operating conditions and the environment in which they function at. Engine performance and durability must be equally considered when operating in environments that challenge engine component lives. This paper describes the various elements that contribute to engine durability when operating in offshore applications with high salt/Sulfur fuels, and a “Systems-Solution” approach to attaining excellent turbine power and efficiency by mitigating the risk of degradation mechanisms that the turbine materials are subjected to. The System Solution to be discussed involves the use of advanced materials in conjunction with appropriate air and fuel filtration systems. Advances in alloys and coatings as well as air and fuel filtration systems have been very strong in the last number of years, and as a result new solutions have emerged to support the new challenging demands and requirements of gas turbines
