Title:
HEAT EXCHANGER FOR GAS TURBINE
Document Type and Number:
Japanese Patent JP05141888
Kind Code:
A
Abstract:

PURPOSE: To hold a core at a ring gear without using a spring and absorb a heat expansion difference and an impact by mounting a seat having an outward recess on the outer periphery of the core, providing an inward recess on the inner periphery of the gear and interposing a hollow roll between both the recesses.

CONSTITUTION: A heat exchanger for a gas turbine is so composed as to mount a ring gear 25 on the outer periphery of a heat accumulation core 21 having a circular shape and air permeability, to support a supporting ring integral with the gear 25 by a guide roller and to rotate the core 21 across an air passage and an exhaust passage of a gas turbine. Seats 23 each having a circular- arc-shaped outward recess 24 are mounted at an equal interval on the outer periphery of the core 21, and a circular-arc-shaped inward recess 26 opposed to the recess member 24 is provided on the inner periphery of the gear 25. Thus, a heat resistant metal hollow roll 27 having a radius smaller than radius of curvature of at least one recess is interposed between both the recesses 24 and 26 to hold the core 21 at the gear 25.
