Abstract: A process based on the combined use of yttrium and magnesium to inhibit vanadium corrosion of high temperature parts of thermal equipment. The combined use of yttrium and magnesium, applied in a variable yttrium/magnesium ratio, compared with conventional magnesium inhibition, may reduce emission of magnesium vanadate and minimize losses of performance due to fouling of the high temperature parts, including in the presence of alkali metals. Further, compared with inhibition based on yttrium alone, it may reduce the inhibition cost and reinforce the protection against combined vanadium pentoxide and sodium sulfate corrosion.

Abstract: A system includes an industrial machine that includes a motor and a motor bearing. The system also includes multiple acoustic sensors disposed adjacent the industrial machine. The system further includes multiple other sensors disposed adjacent the industrial machine. The system even further includes a controller programmed to receive noise signals representative of a noise made by the motor bearing acquired by the multiple acoustic sensors, to receive signals representative of operational conditions of the industrial machine, to analyze the noise signals to determine characteristics of the noise, to analyze the characteristics of the noise utilizing the operational conditions, to compare the characteristics of the noise to a plurality of models associated with different noises made by the motor bearing that are associated with a particular abnormal operation, and to select a model from the plurality of models that matches the characteristics of the noise.

Abstract: This disclosure provides methods and systems for using coatings to control component dimensions during operations of a mechanical system, such as gas turbine combustion air cooling system. The mechanical system may have a component with a critical dimension defined by at least one surface. Upon detecting a change in the critical dimension, such as from surface erosion, a coating additive is deployed into the mechanical system. The surface is coated with the coating additive to offset at least a portion of the change in the critical dimension.

Abstract: A method and system for transitioning a gas turbine from burning gaseous fuel to liquid fuel and purging the liquid fuel therefrom after transfer back to the gaseous fuel are disclosed herein. The method includes pressurizing a volume of liquid fuel in an accumulator with a first volume of motive gas. A valve is opened in response to low gaseous fuel pressure in the gas turbine to permit the volume of liquid fuel to flow through a conduit to the gas turbine. A volume of flushing medium is pressurized in the accumulator with a second volume of motive gas. The valve is opened to permit at least a portion of the volume of flushing medium to flow through the conduit to flush any of the volume of liquid fuel remaining in the conduit after the gas turbine consumes the volume of liquid fuel.
