Abstract

The present invention relates to an axial flow turbine, comprising: a rotor mounting part; a housing having a fluid supply part surrounding the rotor mounting part; a rotor which is installed at a rotation shaft installed in the housing and has a plurality of blades installed in a circumferential direction; and a plurality of injection nozzles, installed in the fluid supply part surrounding the rotor mounting part, for spraying a high-pressure fluid toward the blades, wherein the fluid collision surface of the blades installed at the rotor is formed to be inclined at an angle in the rotational direction of the rotor with respect to the normal axis of the rotation center axis, and the injection nozzles formed in the fluid supply part are installed at an angle parallel to the normal direction of the fluid collision surface of the blades. Due to the aforementioned configuration, the present invention provides the effect of maximizing the rotation rate of a turbine while smoothing fluid flow by optimizing the angle of the fluid collision surface of the blades.

Description

Technical field [0001] The present invention relates to an axial flow turbine, and more specifically, an axial flow turbine in which the blade angle of the rotor is improved. Background technique [0002] Generally, gas turbines or steam turbines used for power generation panels and the like are divided into axial flow turbines in which fluid flows in the direction of the rotation axis of the turbine, diagonal flow turbines in which fluid flows from the rotation axis, and fluid to the rotation diameter Radial turbines flowing in the direction. Among them, in particular, axial flow turbines are suitable for large-capacity power generation panels, and thus are widely used in steam turbines and the like in thermal power plants. [0003] From the viewpoint of economical improvement and environmental load reduction, this axial-flow turbine needs to increase the power generation efficiency of the additional layer of the power generation board, and the high performance of the turbine is ...
