Abstract
A turbine and a method for dismantling a blade of a turbine. A turbine includes a rotor that extends in an axial direction and an accessible combustion chamber, which communicates with an annular hot-gas conduit, in which a plurality of blades that form a blade row is arranged. Each blade has a blade root that is fixed to the internal housing and a blade head that lies opposite the root and faces the rotor, the head being fixed to a fixing ring of the turbine that encircles the rotor. To reduce the down time of a turbine during repair, inspection and/or maintenance work, the blade root and/or the blade head can be fixed by means of a manually detachable clamping device. The clamping device is released from the blade and locked in a parking position beyond a displacement path used for removing the blade through the combustion chamber.
