To provide a heat exchanger for effectively removing dust of a heat transfer tube so as to stably recover waste heat from a lime baking plant.
A gas inlet port connected to an exhaust gas assembly room of a great preheater is at an upper end of a heat exchanger body 10A, and a gas outlet port connected to an assembly duct is at the lower part. A coiled-pipe type heat transfer tube 14 is in a vertical surface, and straight tube parts 14a are horizontal and orthogonal to a gas flow. Outer walls 10B are on the outside of sidewalls of the heat exchanger body to form a dual-wall structure. Openings are on the sidewalls, and both right/left ends of the straight tube parts of the coiled-pipe type heat transfer tube penetrate the openings of the sidewalls of the heat exchanger body to project to the outside. A first suspending means H1 and a second suspending means H2 are respectively between the sidewalls and outer walls. The right/left end parts 14e1, 14e2 of the straight tube parts of the coiled-pipe type heat transfer tube are supported by the first suspending means H1 and the second suspending means H2. The first suspending means includes bending parts composed of link members and hinge pins.
