  • Flow-through arrangement
    Patent number: 11313384
    Abstract: An arrangement having an impeller that rotates about an axis and a stationary diffuser located downstream with guide vanes. The impeller has an inlet for an axial supply flow and an outlet for a radial out-flow, wherein radially and axially extending rotor blades are arranged between a wheel disc and a cover disc of the impeller. The impeller channels are separated from one another in a circumferential direction. The diffuser extends substantially radially along a main flow direction and has an axial channel width. The diffuser has a diffuser inlet and outlet, wherein guide vanes extending axially along a blade vertical direction and radially along a through-flow direction are arranged between the wheel disc side and the cover disc side of the diffuser, which separate the guide vane channels from one another. An inlet edge angle is smaller on the cover disc side than on the wheel disc side.

    Patent number: 11313562
    Abstract: A method for operating a burner arrangement of a heat engine, particularly a gas turbine, having a plurality of burners, each having at least one pilot burner and main burner, in which method, on the basis of a preset operation of the heat engine, the total quantity of fuel supplied to the burners is maintained substantially constant in a load-controlled manner: in a first group of burners, for each burner, both the pilot burner as well as the main burner are supplied with fuel; in a second group of burners, the fuel supply to the main burners is interrupted, while the pilot burners continue to be operated; and the fuel quantity remaining as a result of the interruption of the fuel supply to the main burners of the second group is redistributed to the still active main burners of the first group. CO emissions are reduced as a result.
