Patent number: 7204061Abstract: 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.Type: GrantFiled: November 7, 2002Date of Patent: April 17, 2007Assignee: Mitsubishi Heavy Industries, Ltd.Inventors: Yasunori Terabe, Keita Inoue, Yuji Nakagawa, Kentaro Saeki

Patent number: 6837015Abstract: 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.Type: GrantFiled: November 14, 2002Date of Patent: January 4, 2005Assignee: Mitsubishi Heavy Industries, Ltd.Inventors: Yasunori Terabe, Keita Inoue, Yuji Nakagawa, Kentaro Saeki
