摘要： Disclosed herein is a turbine in which buckets (140, 240) may be easily assembled. The steam turbine includes a plurality of buckets (140, 240) which are axially inserted and assembled along a circumferential portion of a rotor wheel (130) using a dovetail coupling structure, and the dovetail coupling structure of a second bucket (240) which is finally assembled among the buckets includes insertion grooves (231) which are axially spaced on the rotor wheel (130), a platform (243) formed at one end portion of a vane (241), protrusion portions (244) which protrude so as to be axially spaced on the platform (243) and are inserted and coupled to the insertion grooves (231), and a fixing member (245) which fixes the protrusion portions (244) and the rotor wheel (130) by axially passing through them. Consequently, the turbine may be easily assembled and simply perform maintenance by applying a finger type dovetail to the second bucket (240) without cutting of assembly interference portions such as the vane.

摘要： 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.
