Abstract: The invention relates to a method for operating a gas turbine which includes a compressor with annular inlet area, at least two burners, a combustion chamber and a turbine. According to the method, at least one first partial intake flow, consisting of oxygen-reduced gas which has an oxygen concentration which is lower than the average oxygen concentration of the compressor intake flow, and at least one second partial intake flow, consisting of fresh air, are fed to the compressor in an alternating manner in the circumferential direction of the inlet area. In addition, the invention relates to a gas turbine power plant with a gas turbine, the compressor inlet of which includes at least one first segment and at least one second segment which are arranged in an alternating manner around a compressor inlet in the circumferential direction, wherein a feed for an oxygen-reduced gas is connected to the first segment and a fresh air feed is connected to the second segment of the compressor inlet.

Abstract: In a fluid flow machine, especially a gas turbine, axially penetrated by a hot gas stream, the rotor shaft is surrounded by heat shield segments or by base plates of the rotor blades on the rotor side. In the heat shield segments and in the base plates, cooling air chambers are provided, communicating with each other and with a cooling air source, which chambers communicate at least partially with gaps which extend in the longitudinal direction or peripheral direction of the rotor shaft between adjacent rotor blades or between heat shield segments and adjacent base plates of the rotor blades. These gaps are closed off by sealing bands such that a cooling air entry into the hot gas stream is only possible at the ends of the base plates of the rotor blades pointing contrary to the flow direction.

Abstract: The invention relates to a fabric filter system, having a first fabric filtering device in the form of elongated tubular fabric bag; a first gas tank for providing compressed gas; a first pulsing gas duct fluidly connected between the first fabric filtering device and the first gas tank through a first pulsing valve for cleaning the first fabric filtering device. The fabric filter system further includes a second gas tank for providing compressed gas. The second gas tank is fluidly connected with the first gas tank through a control valve. The first pulsing valve is opened to introduce the compressed gas into the first filtering device for cleaning when the control valve remains open. The control valve is closed after a predetermined time. A method for cleaning the fabric filter system is disclosed.

Abstract: An air quality control system (AQCS) 14 useful for treating flue gas FG, such as flue gas FG produced by a fossil fuel fired boiler 12 is described. The AQCS 14 is equipped with a dust separator 37. The dust separator 37 is useful under relatively high dust load conditions downstream from a dry scrubber reactor 36 with limited equipment wear and limited space requirements. As such, the dust separator captures particulate matter with a dust trap that intercepts the flow of particulate matter for collection of the particulate matter in a hopper.

Abstract: A method and a device are disclosed for the safe operation of a gas turbine plant, whose operation is both controlled by at least one process controller, which at least triggers and/or influences operationally relevant processes of the gas turbine plant, and is also monitored by a separate protection unit that is operated independently of the process controller on the basis of at least one first limit value for a safety-relevant operating parameter, wherein the gas turbine plant is subjected to an emergency switch-off once the at least one first limit value is exceeded. In that in the case of a defined transient operating state of the gas turbine plant that can be detected by the protection unit, the at least one first limit value of the safety-relevant operating parameter is raised to a second limit value, wherein the gas turbine plant is protected by an emergency switch-off of the gas turbine plant once said second limit value is exceeded. Furthermore, secondary protective functions can be carried out in the process controller.
