FIXING MECHANISM OF RADIAL DESWIRLER VANE OF COMPRESSOR FOR A GAS TURBINE

摘要

PURPOSE: A fixture structure of deswirler vane in a radial direction of gas turbine compressor is provided to weld the protrusion portion after a deswirler vane is inserted by forming a groove on the upper end portion of casing and to forms the integral deswirler, thereby preventing the leakage of fluid during assembling of deswirler and stably maintaining the fixed shape. CONSTITUTION: A fixture structure of deswirler vane in a radial direction of gas turbine compressor includes a diffuser in a radial direction and an integral deswirler. The diffuser increases a static pressure by reducing the flow speed of fluid flowed into an entrance of combustor. The integral diswirler is formed by inserting a deswirler vane (11) into a groove of casing, and includes one side inserted into an accommodation groove of diffuser, and the other end assembled in the diffuser by being bolted and fixed to the diffuser.
