Patent ID: 6837015

Claim:
A method of forming a fireproof structure for protecting water pipes of a water pipe wall in a combustion chamber against a high temperature atmosphere in the combustion chamber, wherein the water pipe wall has at least one bent part where the pipes are bent such that the water pipes are not arranged in a regular array, said method comprising: filling concavities between adjacent water pipes with refractory castable in the at least one bent part of the water pipe wall where the water pipes are not arranged in a regular array so that the water pipes are embedded in the refractory castable and so that a high temperature atmosphere side wall surface of the water pipe wall at the at least one bent part is formed into an approximately flat surface; and installing approximately flat-shaped refractory tiles over the surface of the refractory castable, said installing including engaging fastening members that are attached to the water pipes with grooves in the refractory tiles and gluing the refractory tiles to the approximately flat surface of the refractory castable with an adhesive agent by spraying the adhesive agent on the refractory castable.
