20130209270 | METHOD FOR RECONDITIONING A BLADE OF A GAS TURBINE AND ALSO A RECONDITIONED BLADE - A method is provided for reconditioning a blade of a gas turbine. The blade includes a blade airfoil, with a pressure side and a suction side, which extends in the blade longitudinal direction between a platform and a blade tip, and has a leading edge and a trailing edge, and is outwardly delimited by a pressure-side wall and a suction-side wall which converge at the trailing edge of the blade airfoil, forming discharge openings for cooling air which are arranged in a distributed manner along the trailing edge between the walls. | 08-15-2013 |
20130212999 | CONTROL SYSTEM - A control system for at least one of steam turbines, gas turbines or power plants includes a sensor system configured to monitor predefined operating parameters, the sensor system including redundant sensors. A central processor arrangement of the control system has an input side configured to receive measurement data from the sensor system and an output side configured to communicate with operation control elements of the turbines or power plants. A sensor side processor circuit is assigned at least to the redundant sensors, the processor circuit being configured to continuously check the sensors for error-free operation, to protect or block the input side of the central processor arrangement from erroneous signals, and to only respectively forward or further process signals from a sensor that has been identified as error-free in one channel. | 08-22-2013 |
20130213224 | LOW PRESSURE STRIPPING IN A GAS PURIFICATION PROCESS AND SYSTEMS THEREOF - Processes for operating an ammonia stripper at a low pressure in a gas purification system include providing a first side-draw stream from the ammonia stripper; heating the first side-draw stream with a second side-draw stream from a regenerator; providing a stripper offgas stream from the ammonia stripper to a stripper overhead condenser; and utilizing the stripper offgas stream as a heat source for a regenerating system fluidly coupled to the stripper overhead condenser. Also disclosed are systems for implementing the processes. | 08-22-2013 |
