Abstract

Provided is an exhaust heat recovery boiler in which any level variation on the inner surface side of a casing is eliminated so that the inner surface can be flattened. The exhaust heat recovery boiler is provided with: a casing (2) into which an exhaust gas (1) from a gas turbine is guided; a heat insulating material (13) that covers the inner surface side of the casing (2); and a heat exchanger that is disposed inside the casing, wherein the casing (2) is divided into a plurality of blocks along the flow direction of the exhaust gas (1). The blocks each have, at both ends thereof, a wall surface structure surrounded by two steel grooves (10). Webs of the steel grooves (10) provided to the adjacent blocks are connected such that respective inner flanges thereof are continuous with each other so as to form steps. Further, the heat insulating material (13) the thickness dimension of which stepwisely varies is disposed in gaps generated by the steps. Accordingly, the inner surface side of the heat insulating material (13) opposed to the heat exchanger in the casing (2) is formed to be flat.
