Title:
AXIAL-FLOW TURBINE HAVING WIDTHWISE-FLOW TYPE SPEED GOVERNING STEP ATTACHED WITH VARIABLE NOZZLE
Document Type and Number:
Japanese Patent JPS5979005
Kind Code:
A
Abstract:
PURPOSE:To reduce the valve pressure loss in the inlet port of the titled turbine and to facilitate the mounting of the variable nozzle by a method wherein the widthwise-flow step is provided on the turbine inlet side of a rotor having the axial-flow step and the variable nozzle is provided in the widthwise-flow step. CONSTITUTION:The rotor 11 is formed of the widthwise-flow step 12 on the side of the steam inlet port and the axial-flow step 13 having blades 14 embedded therein. Further, the variable nozzle 16 is provided on the side of the inlet port of the widthwise-flow step 12 so that the opening degree of the nozzle 16 is adjusted and the quantity of steam corresponding to the opening degree of the nozzle is flowed in. Thus, since no valve used, the valve pressure loss can be reduced. Moreover, due to the provision of the widthwise-flow step in the turbine inlet port, it is possible to mount the variable nozzle easily.
