Abstract
A fireproof structure protects water pipes with stable durability even in a high temperature gas environment. Even in a case where it falls off, it does not leave the water pipes suddenly exposed. The fireproof structure for protecting water pipesB installed on water pipe walls of a combustion gas side is configured by a double-layered structure made up of an outer layer water pipe protective structure facing towards the combustion gas side, which is fireproof tile, and an inner layer water pipe protective structure provided between the outer layer water pipe protective structure and the water pipes, which is fireproof castable. The thickness ratio between the castableand the tileslies within the range of about 2:1 to 3:1, and the ratio between the thickness of the fireproof castable and the radius of the water pipe is set to 1+α:1, wherein the value of α ranges from approximately 0.1 to 0.3. The water pipes are equipped with hanging hooksfor tiles
