IPC: F23R3/42
Filed: 1989-06-30
Abstract: PURPOSE:To eliminate the need for high strength material to a tail pipe by making a sectoral, circular-arcuate part at an output part to a shape more expanded than in a prescribed dimension, then, heating it, giving and holding force to the circular-arcuate part, returning the temperature to the room temperature and setting the circular-arcuate part to a prescribed dimension when the force is removed. CONSTITUTION:The combustor tail pipe 10 of a can-type gas turbine has such a structure that a sectional shape changes gradually and smoothly from an inlet part 1 having a circular sectional shape to an outlet part 2 having a sectoral sectional shape. Then, the sectoral circular-arcuate part of the outlet part 2 is made in advance to a shape more expanded outward than in a prescribed dimension. Thereafter, the force is given by a weight 8 to the circular-arcuate part while it is heated at a temperature higher than a working temperature and held for a fixed time. The circular-arcuate part is made to return to a prescribed dimension when the temperature is returned to the room temperature and the force is removed. In this way, the need for reinforcing a frame, etc., can be diminished.
