Abstract: A gas turbine process includes supplying a fuel to a gas turbine, combusting the fuel in the gas turbine with a hot gas path temperature reaching at least 1100° C. during operation of the gas turbine, and supplying an inhibition composition including at least one yttrium-containing inorganic compound to interact with the vanadium and inhibit vanadium hot corrosion in the gas turbine caused by vanadium as a fuel impurity in the fuel. A process includes supplying an inhibition composition including at least one yttrium-containing inorganic compound to a hot gas path or a combustor of a gas turbine. A fuel composition includes a fuel including at least one fuel impurity including vanadium and an inhibition composition including at least one yttrium-containing compound. An atomic ratio of yttrium to vanadium in the fuel composition is in a range of 1 to 1.5.

Abstract: A power generation plant including a plurality of combustor cans, one or more sensors configured to measure acoustic vibrations from the plurality of combustor cans, and a controller that includes a processor. The processor is programmed to identify a dominant tone of the measured acoustic vibrations, the dominant tone being a frequency where a highest amount of energy lies, determine, for each of the plurality of combustor cans, a frequency of the dominant tone at predefined time intervals, and determine a degradation status of at least one of the plurality of combustor cans based on the frequency of the dominant tone at each of the predefine time intervals for the at least one of the plurality of combustor cans.

Abstract: A fuel nozzle for a turbine engine includes a primary fuel passageway for supplying fuel to a plurality of radially extending fuel injectors arranged around the exterior of the fuel nozzle. A secondary fuel passageway couples an upstream end of the primary fuel passageway to a downstream end of the primary fuel passageway. The secondary fuel passageway acts as a resonator tube to help reduce oscillations in the fuel flowing through the primary fuel passageway.
