EXHAUST DUCT

摘要

An exhaust duct includes a duct plate (21) having a cylindrical shape, a heat insulation panel (23) disposed at a predetermined interval on an inner surface side of the duct plate (21), a heat insulation material (22) disposed between the duct plate (21) and the heat insulation panel (23), and a connecting member (24) configured to connect the duct plate (21) to the heat insulation panel (23) and also including a first plate portion (31) and a second plate portion (32) as a stress absorption unit capable of absorbing stress in two directions intersecting in a longitudinal direction. With this structure, durability is improved by preventing damage of the connecting member between the duct plate and the heat insulation panel.

1. An exhaust duct, comprising:
a duct plate having a cylindrical shape; a heat insulation panel disposed at a predetermined interval on an inner surface side of the duct plate; a heat insulation material disposed between the duct plate and the heat insulation panel; and a connecting member configured to connect the duct plate and the heat insulation panel, and including a stress absorption unit capable of absorbing stress in two directions intersecting in a longitudinal direction, wherein the connecting member is formed by connecting, in an intersecting manner, a first plate portion and a second plate portion which functions as the stress absorption unit.
