Abstract

PURPOSE: To facilitate attaching and detaching of a draft tube piece, by designing the draft tube piece such that it has some inclination angle to the horizontal flange surface of a draft tube.
CONSTITUTION: A draft tube piece 17' is designed such that it has an inclination angle θ1 to the horizontal flange surface of a draft tube 8. By employing such an arrangement, the draft tube piece 17' can be detached with ease by removing fastening bolts at the flange portion and then drawing the piece 17' in the direction of an arrow shown in the drawing while holding the piece 17' slightly upward. Thus, it is enabled to facilitate attaching and detaching of the draft tube piece 17'.
