PROBLEM TO BE SOLVED: To provide a marine boiler structure in which the bending amount of a furnace or a superheater header can be suppressed without impairing features of a marine boiler as an independent boiler.SOLUTION: The independent boiler comprises: a furnace; a fixed supporting leg 20A for supporting a bottom face of a boiler body at a fixed manner at an evaporator side; an evaporator-side slide supporting leg 20 which supports a location different from that supported by the fixed supporting leg 20A, on the bottom face of the boiler body at the evaporator side, while allowing thermal extension in a longitudinal direction of a can; a furnace-side slide supporting leg which supports the bottom face of the boiler body while allowing thermal extension at a furnace side; and a superheater header 11 which is disposed in the longitudinal direction of the can on the bottom face of the boiler body in the vicinity of the fixed supporting leg 20A and the evaporator-side slide supporting leg 20. The superheater header 11 is supported by a superheater support member 40 which suspends and supports both end portions in the longitudinal direction of the can from the side of the bottom face of the boiler body, and a superheater intermediate support member 50 which supports an intermediate part of the bottom face of the boiler body while being supported to the fixed supporting leg 20A or the evaporator-side slide supporting leg 20 in the fixed manner. |
