摘要： A series of upright boiler tubes periodically exposed to the abrasive action of a stream of blowing fluid cleaning medium. Vertically spaced shields mounted on the boiler tubes for protection from the fluid cleaning medium. A split ring casting located between the protective shields to maintain the boiler tubes in an aligned and fixed spaced relationship. The split ring casting is sized to overlap adjacent portions of the protective shields thereby covering any gaps exposing the boiler tubes to the action of the fluid cleaning medium.

摘要： A method of corrosion protecting a tube having an end portion extending into a tube receiving hole of a mud drum of a boiler and the tube produced by that method. The end portion of the tube is provided with a corrosion resistant cladding layer which may contain chromium. Laser cladding is used to produce the corrosion resistant cladding layer, which advantageously tapers along a length of the end portion of the tube. The tube may be swaged before or after the cladding is applied and suitable heat treatments may be performed on the bare or clad tube to develop suitable properties in the tube, the cladding, or a tube-cladding interface.

摘要： A method of welding together the parts of a boiler tube wall panel includes placing at least two parts of the panel to be welded together along a weld line and adjacent each other, and forming a weld along the weld line using a laser beam. The method can advantageously be used to weld boiler tube wall panels solely from one side of the panel. A GMAW process can also be used in combination with the laser beam to form the weld. Where the boiler tube wall panel includes a membrane between tubes, the membrane may be beveled.

摘要： A method of inspecting a tube header bore comprises scoring an oxide scale layer within the bore using a hard scribing tool. The bore is then cleaned using one or more honing brushes having flexible bristles with carbide tips. After sufficiently cleaning the inner surface of the bore a florescent dye is applied to the surface for highlighting surface defects and a visual inspection is made. For easy access to the interior of the bore, the tube is cut at a point spaced from the bore. After the inspection is complete a new length of tube is connected such as by welding.

摘要： A structural framework for supporting the heat exchanger of a steam generator, the former being comprised of serpentine tubes having sloped segments to facilitate the drainage of water from the heat exchanger when the steam generator is shutdown. The structural framework includes paired groups of vertically and diagonally extending first support members contiguously straddling the sloped-tube segments. The paired first support members are rigidly connected by second support members which extend between adjacent sloped-tube segments. The structural framework preserves the spacing between the sloped-tube segments and prevents direct contact between adjoining tube surfaces, but is not attached to the straddled tube segments and, thus, provides a tube supporting fit that is loose enough to permit the tubes to move freely due to expansion and contraction at different rates from that of the structural framework.
