Disclosed herein is a fixture for a bucket for a turbine blade. The fixture includes a rotor wheel that includes a plurality of dovetail grooves. A platform seat is formed between the dovetail grooves and provided with a first insertion groove in a circumferential direction. A bucket includes a platform that inserts into one of the dovetail grooves. A base platform disposed on an upper surface of the platform includes a second insertion groove at a position facing the first insertion groove.

Assembling method of a bucket and a fixture for a bucket for a turbine blade

Disclosed herein is a combustion oscillation estimating apparatus which estimates combustion oscillation in a combustion chamber connected with a burner so that a flame is injected by the burner, the combustion oscillation estimating apparatus including an input unit which receives data including an inlet pressure of the burner, and a control unit which detects a pressure in the combustion chamber based on a shape from the burner to the combustion chamber, a temperature distribution in the combustion chamber, and a shape of the flame. The combustion oscillation estimating apparatus may improve estimation accuracy of the combustion oscillation in the combustion chamber.

Apparatus for estimating oscillation within combustion device

There is provided a turbine including a rotor wheel including a plurality of dovetail grooves and at least one insertion groove, the dovetail grooves and the insertion groove arranged in a circumferential direction of the rotor wheel; a plurality of first buckets, each of the first buckets including a vane, a platform provided at a first end portion of the vane, and a dovetail provided at the platform and having a shape corresponding to a corresponding dovetail groove; at least one second bucket including a vane, a platform provided at a first end portion of the vane, and at least one protrusion portion provided at the platform and configured to be inserted into a corresponding insertion groove of the insertion groove; and a fixing member configured to be inserted through the protrusion portion and the rotor wheel and configured to restrict radial movement of the second bucket.

Turbine with bucket fixing means

Provided is a turbine including a rotor wheel including a plurality of dovetail grooves and a insertion groove, the insertion groove including a first catching groove; a plurality of first buckets, each of the plurality of first buckets including a vane, a platform provided at a first end portion of the vane, and a dovetail provided at the platform and having a shape corresponding to the dovetail groove; a second bucket including a vane, a platform provided at a first end portion of the vane, and a protrusion portion and configured to be inserted into the insertion groove, the protrusion portion including a second catching groove; and a fixing member configured to be inserted into each of the first and second catching grooves, the fixing member configured to restrict radial movement of the second bucket.
