摘要： Disclosed are systems and methods for active inlet turbine control. The systems and methods may include receiving a plurality of signals, determining a temperature gradient across an inlet of a gas turbine engine, and transmitting an activation signal to a modulating valve. Each of the plurality of signals may correspond to a temperature measured by one of a plurality of sensors located proximate the inlet of the gas turbine engine. The temperature gradient across the inlet of the gas turbine engine may be determined based on the plurality of signals. The activation signal may be operative to open or close the modulating valve based on the temperature gradient.

摘要： A method for starting a steam turbine can comprise electrically decoupling a generator configured to be driven by the steam turbine from a power supply, controlling power from the power supply to a frequency converter, and operating the generator as a starter motor with power from the frequency converter to turn the steam turbine. A power plant system can comprise a steam turbine, a generator configured to be driven by the steam turbine to supply power to a grid system, a first switch to electrically couple and decouple the generator from the grid system, a frequency converter electrically coupled to the generator, and a second switch to electrically couple and decouple the frequency converter form the grid system.

摘要： A waste water processing system includes an upflow contacting column having a flue gas input for receiving flue gas having a temperature of at least 500 degrees F., a waste water input, and a flue gas output. The waste water input is coupled to a fluid injector, e.g., atomizing nozzles, positioned in the throat of a Venturi portion of the upflow contacting column or in a sidewall of the throat of the Venturi portion of the upflow contacting column. The flue gas in the upflow contacting column has a high velocity, e.g., a gas velocity exceeding 65 fps in the throat of the Venturi portion of the upflow contacting column at a position where the fluid injector is located. Drying additives such as recycled ash, lime, and/or cement may be, and sometimes are, input into the upflow contacting column downstream of the waste water input.

摘要： A method for measuring a non-magnetic coating thickness upon a non-magnetic gas turbine component, such as a hot gas path component, can comprise applying a magnetic coating, such as a ferrous coating, upon the non-magnetic gas turbine component, applying a non-magnetic coating, such as a metallic bond coating, upon the magnetic coating, and measuring a thickness of the non-magnetic coating with a magnetic induction probe. The magnetic induction probe can be calibrated to the magnetic coating before the non-magnetic coating is applied. Measuring of the thickness of the non-magnetic coating can be used to validate spray patterns of automated spray processes. The magnetic and non-magnetic coatings can be stripped from the gas turbine component and used to validate additional spray patterns.
