Abstract: A method, control unit and rotating machine for determining a fuel split setting value for adjusting a fuel split setting for a combustion device, the fuel split setting defining a relation between main fuel and pilot fuel. The method includes: retrieving a first information item correlated to heating value of supplied main fuel; retrieving a second information item correlated to combustor operating condition; retrieving at least one third information item representing stability of combustion; selecting a predefined pair of minimum and maximum boundary curves for the fuel split setting from a plurality of predefined pairs based on the first and second information items, the minimum and maximum boundary curves defining a band of fuel split settings permitted for a range of second information item values; determining the fuel split setting value within the selected pair of minimum and maximum boundary curves based on the third information item.

Abstract: An arrangement for a gas turbine, including: a rotor disk portion comprising an engaging section; a blade unit portion including an engaging section, wherein the respective engaging sections are engaged to circumferentially and radially fix the rotor disk portion and the blade unit portion relative to each other; a locking plate connected to the rotor disk portion and the blade unit portion such as to axially fix the blade unit portion with respect to the rotor disk portion, wherein the locking plate is axially spaced apart by a spacing from an axial end of the engaging portions of the rotor disk portion and/or the blade unit portion leaving a void region axially between the engaging portions and the locking plate.
