Abstract: A burner configuration includes approximately concentrically disposed annular conduits for delivering various operating media. A plurality of outlet nozzles admix a gaseous medium or a liquid medium in finely distributed form with an air flow flowing in an approximately conically tapering outer annular-conduit air delivery system. A further annular conduit on an inflow side discharges into the annular-conduit air delivery system above the outlet nozzles.

Abstract: A heat shield configuration for structures carrying hot fluid, especially metal components of gas turbine systems and combustion chambers, includes adjacent mushroom-shaped ceramic material heat shield elements being mutually spaced apart defining expansion gaps therebetween, each of the heat shield elements having a surface-covering polygonal cap portion being flat or curved with straight or curved outer edges and a shank portion with an end facing away from the cap portion, the ends of the shank portions having beads formed thereon. A support structure on which the heat shield elements are anchored at a distance defines a space between the support structure and the heat shield elements to be subjected to fluid through channels formed in the support structure. Clamps secure the beads to the support structure and additional devices are provided for supporting the heat shield elements against the support structure.

Abstract: A hybrid burner has a main burner operable with premixing combustion and an auxiliary burner operable with premixing and/or diffusion combustion alone or operable to furnish a pilot light for the main burner. A fitting connects at least one hybrid burner to a main supply apparatus and an auxiliary supply apparatus. The fitting includes a change-over element. A main feed line communicates between the change-over element and the main supply apparatus, an auxiliary feed line communicates between the change-over element and the auxiliary supply apparatus, a main tie line communicates between the change-over element and the main burner and an auxiliary tie line communicates between the change-over element and the auxiliary burner. The change-over element is operable in at least one first and at least one second switching state. In the first switching state the main feed line communicates with the main tie line and the auxiliary feed line communicates with the auxiliary tie line.

Abstract: Two-stage combustion of nitrogen-containing gas with low NO.sub.x emissions, in a combustion chamber, wherein first, pre-combustion is performed in a primary stage at an air number of approximately .lambda.=0.6 to 0.9 and subsequently post-combustion is performed in a secondary stage at an air number of approximately .lambda.=1.3 to 2, characterized in that in the primary stage, an inert substance is supplied via a multiplicity of openings in the walls of the primary stage, which substance cools the walls and keeps the combustion zone remote from the walls.

Abstract: Combined gas turbine/steam turbine plant, in which the exhaust gas line of the gas turbine block containing an air compressor, combustion chamber, gas turbine and generator is connected on the primary side to a steam generator which, in turn, comprises parts of the steam turbine block which also contains a high pressure and a low pressure turbine, a condenser, a feedwater tank and a feedwater pump. The combustion chamber of the gas turbine block is connected to the output of a coal gasification plant, the air separation unit which has an outlet for the separated nitrogen and the gasifier. The gasifier is followed by a steam generator for utilizing the raw gas heat and a heat exchanger for heating the purified gas by the raw gas. The steam generator arranged ahead of the raw gas/purified gas heat exchanger is designed as a high pressure steam generator, the secondary output of which is connected to the output of the steam generator of the steam turbine block.
