Abstract: Systems and methods for pulse-width modulation of late lean liquid injection velocity can be provided by certain embodiments of the disclosure. In one embodiment, a gas turbine combustor utilizing a late lean injection scheme can be provided, wherein the combustor can include a combustor liner and a transition piece. Methods described herein can allow for dynamic and intelligent adjustment of the late lean injection scheme based on a duty cycle and, optionally, a measured combustion gases temperature profile. The adjustments can involve a pulse-width modification of the duty cycle, which in turn can affect a fuel introduction velocity. Dynamic control of the fuel introduction velocity can provide for improved fuel droplet penetration and moving the heat release zone away from walls of the transitional piece.

Abstract: Provided is a system for soft switching of an electromechanical relay in a lighting control system using a sensor to detect a specified non-zero position in the electrical input waveform. Following this non-zero position, an adaptive time delay is applied before activation of the relay coil. An error detection circuit measures a time error between relay operation and the zero electrical input condition. This error signal is used to update the adaptive time delay for future relay operations. Using such a procedure has been shown to limit electrical stress on the relay, and therefore lengthen its life.

Abstract: Systems and methods for generating solution recommendations for power plant operation can be provided by certain embodiments of the disclosure. In one embodiment, a system may include a processor configured to collect power plant operational data from power plant components. The power plant operational data may be analyzed to identify cost factors for the power plant components. Based at least in part on the power plant operational data and the cost factors, upgrade opportunities for the power plant components may be determined. Financial values may be calculated for the upgrade opportunities. Based at least in part on the financial values, recommendations may be generated using a product interaction database and provided as an electronic output to a user.

Abstract: One aspect of the invention is a system for providing navigation control for a tabletop computer system. The system includes a multi-touch display and processing circuitry coupled to the multi-touch display. The processing circuitry is configured to display a user interface on the multi-touch display and render a navigation pane on the multi-touch display. The navigation pane includes a reduced-scale copy of the user interface. The processing circuitry is also configured to detect a touch-based input at a position on the navigation pane and determine a scaled position on the user interface corresponding to the position on the navigation pane. The processing circuitry is further configured to interpret the touch-based input at the position on the navigation pane as an equivalent touch-based input at the scaled position on the user interface and trigger an event corresponding to the equivalent touch-based input at the scaled position on the user interface.

Abstract: One aspect of the invention is a system for providing a multi-touch inspection tool. The system includes a multi-touch display and processing circuitry configured to display an inspection tool for a chart on a user interface on the multi-touch display. The inspection tool includes a multiplier-scale control and a precision control. The processing circuitry is also configured to determine a base level of scaling to apply to the chart based on a current value of the multiplier-scale control and detect a touch-based input on the precision control for a precision adjustment of the chart. The precision adjustment is based on linear steps dynamically defined with respect to the base level of scaling. The chart is adjusted in response to the touch-based input on the precision control as a combination of the base level of scaling determined by the multiplier-scale control and the precision adjustment of the precision control.

Patent number: 8959921
Abstract: A combustor for a gas turbine engine includes a plurality of primary nozzles configured to diffuse or premix fuel into an air flow through the combustor; and a secondary nozzle configured to premix fuel with the air flow. Each premixing nozzle includes a center body, at least one vane, a burner tube provided around the center body, at least two cooling passages, a fuel cooling passage to cool surfaces of the center body and the at least one vane, and an air cooling passage to cool a wall of the burner tube. The cooling passages prevent the walls of the center body, the vane(s), and the burner tube from overheating during flame holding events.
