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 pipes 25B 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 13, 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 12. The thickness ratio between the castable 12 and the tiles 13 lies 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+?:1, wherein the value of ? ranges from approximately 0.1 to 0.3. The water pipes are equipped with hanging hooks 15a for tiles 13.

Abstract: This invention concerns a heat-resistant assembly having a heat-resistant block conformed to the contours of boiler tubes and the surface of their connecting rib. The heat-resistant assembly has an arm which protrudes from the surface of the rib toward the heat-resistant block and which has a catch on the end. The block has an indentation in which the catch on the arm engages. The block can be hung on or removed from the tube assembly by means of the arms and indentations. The heat-resistant assembly is further distinguished by the fact that a space is created between the end of the arm and the indentation of the block. A fusible substance, which will melt when the temperature of the arm exceeds a given value, is placed in the space. The heat-resistant assembly is further distinguished by the fact that an indentation is formed in the block in which a heat-resistant sleeve is adhered to engage the arm. This arrangement makes it possible to manufacture the heat-resistant block using press molding.

Abstract: An installation for protecting water pipes is easily installed, even in areas of a water pipe wall where bends exist, can be inexpensively manufactured, and delivers stable longevity in high temperature environments. A refractory castable process embeds refractory castable 12 in concave areas between adjacent water pipes, at least in bend areas 24 where the pipes bend, to create an approximately flat surface on the water pipe wall 26 that faces the high temperature side. A refractory tile process installs approximately flat-shaped refractory tiles 13 over the surface of the embedded refractory castable 12. This refractory tile process for the refractory tile 13 includes a process to insert fastening members 15 previously installed on the foregoing water pipe 10 into a groove formed in the refractory tiles 13 to hold the tiles in place and a process to bind the refractory tiles 13 to the embedded refractory castable with an adhesive material.

Abstract: A support fitting for the heat-resistant block to protect boiler tubes, which protrudes upward at a right angle from the surface of the rib between two boiler tubes, and which is welded on the rib and has a catch to engage with the heat-resistant block on the end. The support fitting is provided with a welding surface to be welded on the rib and shaped narrower by chamfering, and a single globule of a deoxidizing conductive material used as flux is attached to the narrowed welding surface, and is a vertical piece or rod which extends a fixed distance perpendicular from the rib. The support fitting includes a first upper surface being kept horizontal to support a ferrule, which can tightly engage with the ferrule for arc stud welding, thereby the ferrule can shield the welding surface, and a second upper surface which engages with the heat-resistant block.

Abstract: The objective of this invention is to provide a support fitting for a heat-resistant block to protect boiler tubes which can be easily and reliably stud-welded without losing any of its function as a support fitting. The support fitting according to this invention is used to attach to the heat-resistant block to protect boiler tubes. It protrudes upward at a right angle from the surface of the rib between two boiler tubes, and it is welded on the rib. The support fitting has a catch to engage with the heat-resistant block on its end. The support fitting according to this invention is distinguished by the fact that the welding surface of the support fitting to the rib is shaped narrower, and by the fact that a single globule of a deoxidizing conductive material used as flux is attached to the narrowed welding surface.
