An object of the present invention is to provide corrosion resistance and the boiler and a manufacturing method thereof with a furnace wall with erosion resistance, and the repairing method.
A boiler of the present invention, added from the air supply unit by introducing the combustion air to a boiler for performing furnace denitration, a region which can be a reducing atmosphere during operation of the boiler, which constitute the furnace wall on the outer peripheral surface of the base pipe 13 of the heat transfer tube, a protective portion 16 and corrosion layer 14 and wear layer 15 are laminated in this order, the corrosion layer 14 is composed of a solid solution strengthened nickel-base alloy, wear-resistant layer 15 is composed of a wear-resistant material.
