Abstract: Multifuel burner having outlet locations for a plurality of fuels respectively connected with associated fuel feeding spaces arranged at a head of the burner, at least one of the fuel feeding spaces being for fuel gas and encompassing a plurality of outlet nozzles arranged annularly in a nozzle head, includes tube conduits connecting the outlet nozzles for fuel gas to the respective fuel feeding space associated therewith; the tube conduits having means for compensating for expansion of the tube conduits; the outlet nozzles having discharge openings directed outwardly at an angle of 20.degree. to 80.degree.

Abstract: A gas turbine is disclosed having at least one turbine stage with hot gas flowing axially through the one stage. At least one balance piston is provided on the shaft to equalize an axial thrust and is located adjacent to at least a first pressurized fluid chamber. The first pressurized fluid chamber is adjacent to a hot gas intake of the turbine stage and is separated from at least a second pressurized fluid chamber by a first transfer gasket co-acting with the balance piston. Pressurized fluid within the first fluid chamber has a pressure greater than the pressure of the hot gas in the vicinity of a hot gas intake. A cooling system is connected to the second fluid chamber for supplying a cooling fluid. A slot of the first transfer gasket is selected so that a pressure difference between the first and second fluid chambers at least partially brings the axial thrust into equalization through the balance piston.

Abstract: A combustion chamber of a gas turbine engine has a combustion cowl and transition piece with at least one air gap provided therebetween. The air gap opens into an intermediate chamber having two throttles which are arranged oppositely with respect to one another. The two throttles are provided in a cooling jacket which is divided into two portions by the throttles. The air gap permits the combustion cowl and transition piece to expand freely with respect to each other. The two throttles are arranged so that fuel gas leaving the combustion chamber provides an injector effect to expedite the flow of a coolant such as air through the air gap.
