Abstract: A sensor system for a turbomachine having an axis is disclosed. The sensor system includes a mounting member including a body configured to be mounted to only a circumferential portion of a circumferential interior surface of a casing of the turbomachine. A plurality of sensors are coupled to the mounting member and configured to measure an operational parameter of the turbomachine.

Abstract: A new approach to the production of coke. In this process multiple optimized value streams are produced from a coke facility located at mine mouth or locally at an existing plant. As part of the process, lower cost Indiana/Illinois Basin-type coals are blended with conventional metallurgical coals. The blending process is optimized to meet coke quality requirements and simultaneously to obtain a pyrolysis gas composition suitable for production of ancillary products including liquid transportation fuels, fertilizer, hydrogen, and electricity. By using lower cost Indiana/Illinois Basin coal it is possible to reduce net coal costs. This process provides a new direction and approach for the production of coke in the future that optimizes value over multiple product streams while reducing both business and technological risk.

Abstract: Embodiments of the present invention have the technical effect of automatically testing an overspeed protection system of a powerplant machine comprising at least one shaft. An embodiment of the present invention may automatically test the overspeed protection system while the powerplant machine is decelerating from full-speed-no-load (FSNL). Another embodiment of the present invention may automatically test the overspeed protection system of the powerplant machine while the powerplant machine is accelerating to FSNL.

Abstract: A system for operating a thermal power plant during off-peak demand intervals includes a gas turbine having a compressor, a combustor connected to a fuel control system, a turbine and a sensor configured to sense ambient conditions around the gas turbine. The fuel control system and the sensor are in communication with a controller. The controller is configured to receive a user input that corresponds to a value for an operational boundary condition of the thermal power plant and to monitor ambient conditions through the sensor. The controller is further configured to generate a predicted emissions level value for the gas turbine based on the monitored ambient conditions and to generate a command signal to adjust at least one operational parameter of the gas turbine based at least in part on the predicted emissions level value and the value of the operational boundary condition of the thermal power plant.

Abstract: Embodiments of the present invention have the technical effect of automatically testing an overspeed protection system associated with multiple powerplant machines of a powerplant. An embodiment of the present invention may automatically test the overspeed protection system while at least one of the powerplant machines is in the process of shutting down. Another embodiment of the present invention may automatically test the overspeed protection system by adjusting the speed of a shaft while at least one of the powerplant machines operates at full-speed-no-load.

Abstract: Embodiments of the present invention have the technical effect of determining when to test an overspeed protection system of a powerplant machine. As described herein, embodiments of the present invention may be applied to a wide variety of powerplant machines, each comprising a shaft. After determining that test of the overspeed protection system should be performed, embodiments of the present invention may allow for a variety of methods to test the overspeed protection system.

Abstract: Embodiments of the present invention have the technical effect of automatically testing an overspeed protection system of a powerplant machine comprising a shaft and integrated with a safety control system. An embodiment of the present invention may automatically test the overspeed protection system while the powerplant machine is in the process of shutting down. Another embodiment of the present invention may automatically test the overspeed protection system of the powerplant machine by adjusting the speed of a shaft while operating at full-speed-no-load.
