Abstract: A measuring device housing for a sensor component, which detects a physical parameter without contact is provided, having: a coupling apparatus for supplying at least one flushing medium and at least one signal transmission line in the housing interior, a guide pipe arranged on the coupling apparatus having a longitudinal axis and a probe head fastened on the end section of the guide pipe. The guide pipe is designed to conduct or accommodate the at least one cooling medium and the at least one signal transmission line up to the probe head. The probe head and the end section, relative to the longitudinal axis of the guide pipe or the probe head, each have radially extending passages for conducting the cooling media from the end section into the probe head and the reverse, as applicable.

Abstract: Disclosed is a gas turbine for a thermal power plant, especially a gas turbine, comprising a rotatable rotor and a duct which can be penetrated by a gas and in which turbine blades for driving the rotor are disposed. The inventive gas turbine is characterized by a blocking device which at least partially prevents the gas from penetrating the duct in a closed position.

Abstract: A method for reducing self-induced flame oscillations is provided. In a first fluid mass flow flowing through a jet nozzle from a fluid inlet opening to a fluid outlet opening, a second fluid mass flow is injected on an axial position of the jet nozzle positioned downstream from the fluid inlet opening. One fluid mass flow includes air, and the other fluid mass flow includes a fuel. A second method for reducing self-induced flame oscillations is also provided. In a first fluid mass flow flowing through a jet nozzle from a fluid inlet opening to a fluid outlet opening, a second fluid mass flow is injected on a radial position of the jet nozzle in relation to the circumference of the jet nozzle. One mass flow includes air and the other fluid mass flow includes a fuel. Burners which ensure the execution of the method are also provided.

Abstract: A method for stabilizing the flame of a premixing burner, comprising a reaction chamber containing a fluid is provided. The method includes injecting an air-fuel mixture into the reaction chamber at a speed that is different from that of the fluid present in the reaction chamber, adjusting the speed such that vortices form at the boundary between the air-fuel mixture and the surrounding fluid. A premixing burner including a reaction chamber and at least one premixing spray nozzle opening into the reaction chamber is also provided. The premixing burner injects an air-fuel mixture into the reaction chamber at a speed that is different from that of the surrounding fluid, the speed being adjusted such that vortices from at the boundary between the air-fuel mixture and the surrounding fluid.

Abstract: A method for protecting a burner from being heated excessively during the combustion of a fuel in a combustion chamber is provided. The fuel is injected through a fuel nozzle at the same time as an inert gas in the surroundings of the injected fuel is injected into the combustion chamber in such a manner that the fuel is separated spatially from an oxidizer by the inert gas until an ignitable mixture of the fuel is produced.

Abstract: A method for operating a premixing burner is provided. The premixing burner includes a premixing zone. An air mass flow and fuel may be injected into the premixing zone, and a potential hot gas backflow area may form. A fluid containing no fuel is injected downstream from the fuel injection into the premixing zone in order that a hot gas backflow area does not form. A premixing burner including a premixing zone is also provided.

Abstract: A burner configuration includes a combustion chamber. A multiplicity of burners are disposed in the combustion chamber. Each of the burners has an outlet opening into the combustion chamber. Flow-guidance elements each at least partly form a respective one of the outlets of at least some of the burners. The flow-guidance elements project into the combustion chamber for guiding a fuel-gas flow discharging from the burners into the combustion chamber. As a result, combustion oscillations are suppressed.
