Abstract: The invention is directed to a turbine having a turbine housing or casing. The turbine housing includes a carrier ring and a ring contour component which is fastened to the carrier ring. The ring contour component has a circumferential flange with which it bears against an annular end face of the carrier ring. At least one hold down is provided which enables the flange of the ring contour component to be releasably fixed against the end face of the carrier ring. The turbine is configured to be part of a micro gas turbine in a combined heat and power cogeneration system.

Abstract: A burner head for a burner defines a burner longitudinal axis along which the burner extends. The burner head includes a base body and at least one oxidant duct defining a duct longitudinal axis. The oxidant duct is arranged in the base body at a radial spacing to the burner longitudinal axis. A fuel duct body is inserted into the oxidant duct and at least one fuel nozzle is configured on the fuel duct body so as to open into the oxidant duct.

Abstract: An installation has a process chamber defining an inner space having a tunnel-like form defining a receiving region for workpieces. The process chamber has a portal for the supply or discharge of workpieces and has a device for introducing gaseous fluid into the inner space. The device has a nozzle for producing a fluid stream curtain between the portal and the receiving region. A device supplies fresh air introduced into the receiving region at a side of the fluid stream curtain facing away from the portal. The installation has a pivotable guide contour projecting into the inner space and the nozzle or aperture is in the form of a slot which supplies the gaseous fluid to the inner space via the ceiling with a flow direction oblique relative to the floor. The gaseous fluid supplied via the nozzle to the inner space is guided on the guide contour.

Abstract: The invention relates to an installation having a process chamber which comprises an inner space having a receiving region for workpieces. The process chamber has an opening for the supply or discharge of workpieces. The process chamber is constructed so as to have a device for the introduction of gaseous fluid into the inner space, which device has at least one nozzle or aperture for the production of a fluid stream curtain between the opening and the receiving region for workpieces. The process chamber has a device for supplying fresh air, with which device fresh air can be introduced into the receiving region at a side of the fluid stream curtain, which side faces away from the opening.
