A method of operating a burner, in particular, a burner of a gas turbine, and a burner configuration include supplying an adjustable burner with fuel through a supply line. The fuel quantity is set by an opening of a control element as a function of a selected output of the burner. A calorific value of the fuel is determined, and the degree of opening is calculated and directly set using the output and the calorific value, resulting in a variable output control that is operationally reliable with respect to perturbations. A controller is connected to the control element having a selectable opening for setting the fuel quantity. In the controller, the degree of opening can be determined as a function of the output, the type of the fuel, and a pressure loss in the fuel supply line, and a corresponding signal can be transmitted to the control element such that the degree of opening is set.

An optical waveguide with a tubular or hose-like housing is provided, which is used in a high-temperature environment, such as, for example, in a burner. The housing has an input opening, an output opening and a center line extending from the input opening to the output opening. In the interior of the housing, transparent spheres are lined up along with center line. The light is guided on account of the refraction of a light beam upon entering and exiting from the transparent spheres.

The invention relates to a gas turbine, with a flow path for a hot gas, enclosed by a channel wall with at least one measuring probe, arranged in the channel wall, for determination of a parameter of the hot gas, said measuring probe comprising a temperature-resistant measuring tip in contact with the hot gas and a measuring line, arranged outside the flow path in a protective sleeve. According to the invention, such a gas turbine with a structurally uncomplicated protective sleeve for measuring lines from measuring probes, in which the measuring lines can be economically fitted and securely protected from excessively high operating temperatures, may be achieved, whereby the protective sleeve has a flow of coolant running therethrough which may be taken from a coolant supply connected to the protective sleeve.

A method to determine a mass proportion of a first component of a multi-component fluid is provided that includes separating the first component in a separation step at least in part from the multi-component fluid, determining at least two reference flow rates, selected from a flow rate of the multi-component fluid supplied to the separation step, a flow rate of a residual fluid resulting from the separation of the first component, and a flow rate of a separation fluid accumulating in the separation step, and determining the mass proportion of the first component from the selected reference flow rates, taking into account a non-separated residual content of the first component in the residual fluid. An extraneous content of an additional separated component of the multi-component fluid is additionally taken into account.
