摘要： A burner arrangement for a combustion chamber for combustion of fluid fuels has a main burner and pilot burner arranged centrally within the main burner for the ignition and/or stabilization of the combustion of the main burner. The main burner has central fuel feed arrangement arranged around the pilot burner, an annular air duct surrounding the central fuel feed arrangement for the supply of combustion air, first fuel nozzles for injection of substantially gaseous fuel into the annular air duct. The first fuel nozzles are fed from a first fuel distributor in the central fuel feed arrangement, and second fuel nozzles for the injection of a substantially liquid fuel into the annular air duct are fed from a second fuel distributor in the central fuel feed arrangement. Ducts are provided which branch off from at least one of the fuel distributors and issue into the pilot burner.

摘要： A pipe connection for conducting a fluid that is under pressure is provided, having two tubular connection parts for a conical clamping connection, which are screwed together by a union nut while one is inserted in the other, wherein each connection part has a conical sealing surface that contacts the other in a sealing manner and wherein an annular groove is provided in one of the sealing surfaces. In order to enable the pipe connection also to conduct a fluid having cycling or varying temperature, the inner of the two connection parts has thermal insulation on the inside of the pipe at least in the axial segment of the sealing surface of the connection part, wherein the thermal insulation tube has a cam or a collar on the outer surface, which engages in a recess, which is axially bounded by the two connection parts.
