摘要： The method for fabrication of corrosion-resistant tubing using minimal quantities of specialized material results in corrosion-resistant tubes with a reduced capital cost. In contrast, the disclosed method uses a straight weld made along the length of the tube, rather than a spiral weld that follows its circumference. The straight weld passes up and down the tube, but only on one side, or approximately 50%, of the tube. Following application of the corrosion-resistant material by straight welding, two or more tubes are joined together into an array.

摘要： An array of tile assemblies is fixedly connected to a common waterwall panel to form a refractory liner for an incinerator. Each tile assembly includes a unitary, clip-type, metallic anchor, which is directly welded to the waterwall panel, and a solid refractory tile slidably connected to the anchor through a dovetail locking mechanism. The rear surface of the refractory tile includes a longitudinal rib from which projects a dovetail pin configured to receive the anchor. The longitudinal rib increases the overall thickness of the refractory tile through the region of interconnection with the anchor. In this manner, the anchor is suitably protected by the refractory tile from intense heat which may otherwise cause mechanical failure in the locking mechanism. Additionally, the solid construction of refractory tile both limits the presence of air gaps within the tile assembly and reduces the likelihood of tile fragmentation or cracking.

摘要： 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.

摘要： A fluidized bed combustion method in which a recycle heat exchanger is located adjacent the furnace of the combustion system. A mixture of flue gases and entrained particulate materials from a fluidized bed in the furnace are separated and the flue gases are passed to a heat recovery section and the separated particulate material are passed back to the furnace. The walls of the furnace are formed by water tubes, and refractory metal material is placed adjacent the walls to control the heat absorption by the water passing through the tubes. The amount of refractory is selected in accordance with the desired operating temperature of the furnace.

摘要： A furnace water cooled tube wall portion (10) is separated from heated gasses by cast refractory material (12). A metal isolation plate (14) against the tubes (18) separates the tubes from the refractory material (12) and has projecting elongated anchors (30) with shanks (32) attached at spaced locations to mechanically join the refractory material to isolation plate (14). Anchors (30) have conical chamber washers welded to shanks (32) to shield the locations from cast refractory material at the spaced locations. This permits bending of shanks (32) to accommodate thermal expansion force created movement between isolation plate (14) and the refractory material (12).
