Title:
COOLING STRUCTURE OF GAS TURBINE TAIL PIPE
Document Type and Number:
WIPO Patent Application WO2005005888
Kind Code:
A8
Abstract:
A cooling structure of a gas turbine tail pipe, wherein a plate spring (6) of shook shape in cross section is fitted, from the underside, near the other end (b) of an impingement cooling plate (4). The lower side one end (c) of the plate spring is fixedly welded to a rib (1d) and the upper side other end (d) thereof is freed and allowed to abut on the impingement cooling device (4) near the other end (b) thereof by the elastic force thereof. Thus, a clearance formed between the impingement cooling plate (4) and a tail pipe (1) can be shielded on the rib (1d) side while avoiding that a thermal stress occurred, for example, in the rib (1d) affects the impingement cooling plate (4).
