A device for connecting a blade to a rotor shaft of a continuous flow machine, includes a first fork foot which has a quantity of first foot lugs with first bore holes, a second fork foot which has a quantity of second foot lugs with second bore holes, and at least one connection bolt which passes through first and second bore holes to connect the first fork foot to the second fork foot. The device has a first area with a predetermined first diameter difference between a first inner diameter of one of the bore holes and a first outer diameter of the connection bolt, and a second area with a predetermined second diameter difference between a second inner diameter of one of the bore holes and a second outer diameter of the connection bolt, wherein the first diameter difference and the second diameter difference differ from one another.

A device for igniting a combustion in a combustion chamber of a gas turbine has a housing fitted with an end piece and with a head piece. Hitherto, an ignition conductor comes into contact with combustion air. Moreover, fragments of a partial ceramic insulation can lead to damage. To improve the quality of ignition, the ignition conductor and a gas conduit are disposed to run parallel to one another within a housing. The ignition conductor is surrounded by a protective sleeve, and an annular space between the ignition conductor and the protective sleeve is filled completely with a ceramic material. An annular disc serving as an ignition electrode is mounted on that end of the protective sleeve that projects into the head piece.

In a steam power station, the condensate used as feedwater is preheated up close to the boiling temperature by means of partial steam mass flows from the turbine steam quantity. Due to the steam extraction, the following steam-turbine stages can draw less power from the steam fluid. To avoid the reduction in the power output at the following steam-turbine stages, provision is made for the waste heat from fuel cells to be used for preheating the condensate. Due to the preheating of the feedwater from the waste heat of the fuel cells and the associated increase in the steam quantity participating in the expansion, an increase in the efficiency of the steam process is achieved.
