20080264358 | End Support Configuration for Steam Tubes of a Superheater or Reheater - End support for parallel tubes of a superheater or reheater with a bend tubular portion, a linear tubular portion extending away from each end of the bend tubular portion, and a supporting member formed on a curved section of the bend tubular portion. The tubular portions form a connection between two consecutive parts of a fluid passage. In a preferred embodiment, the tubular portions and the supporting member are integrally formed, molded or cast of a suitable material, such as carbon steel, stainless steel, chromium-nickel alloy, or other suitable alloys that have high temperature strength and oxidation resistance. The supporting member is configured to securely attach the end support configuration to the wall support brackets on the wall support tube. Preferably, the supporting member and the wall support bracket slide on one another to provide relative movement between the superheater tubes and the wall support or boiler tubes. | 10-30-2008 |
20080271686 | Link Type Seismic Tie For Boilers - A link-type seismic tie is provided between a steel structural support and a buckstay, and includes two horizontally arranged, parallel, and spaced apart link members, which are connected at their ends to large vertical pins. Each of the link members includes two horizontally arranged and parallel longitudinal outboard stringers and a horizontally arranged and parallel longitudinal center stringer centered between the two outboard stringers. Each link member further includes finger plates standing upright and spaced apart from each other relatively perpendicular to the longitudinal stringers. The finger plates are held between each of the outboard stringers and the longitudinal center stringer. A gusset plate connects the outboard stringers to a pin plate, which is connected to a large pin at the buckstay. The other end of the link members is connected to a large pin at the steel structural support via the ends of the outboard stringers. | 11-06-2008 |
20080276885 | Boiler plant, a support structure and a method for supporting the walls of a steam boiler of a boiler plant - A boiler plant, which comprises a boiler ( | 11-13-2008 |
20100139580 | ARRANGEMENT FOR THE ADJUSTMENT OF EQUIPMENT FOR A BOILER - The arrangement is for positioning equipment in association with an opening in a boiler wall and has a rotation mechanism that rotates the equipment around a virtual rotation axis that lies within the outer wall of the boiler. During the use of a liquor spreader for the introduction of combustible material, the opening of the liquor spreader is arranged in the virtual center of rotation so that the point at which the combustible material is introduced is retained independently of the angle of rotation. The liquor spreader is united either with a glide device or the guide in the rotation mechanism. | 06-10-2010 |
20100294215 | METHOD OF AND APPARATUS FOR SUPPORTING WALLS OF A POWER BOILER - A method of and an apparatus for supporting walls of the furnace of a thermal power boiler, in which the furnace is suspended to hang on a supporting plane of the upper portion of steel structures especially arranged for the purpose, and the walls, being formed of water tubes, are supported horizontally at least by buckstays positioned substantially perpendicular to the water tubes, and vertical pillars, located outside the buckstays, are attached to the ground or the foundations of the boiler building. At least two of the walls, located on opposite sides of the furnace are supported in such a way that loads directed perpendicularly to the walls are transferred by the vertical pillars to internal stresses of at least one rigid plane surrounding the boiler. | 11-25-2010 |
20110094455 | BUCKSTAY CONNECTING SYSTEM - A buckstay connecting system includes a socket part that is fixed to the horizontal buckstay being separated from a lower end of the vertical buckstay between the lower end of the vertical buckstay and the horizontal buckstay, and an insertion part that is fixed to a lower portion of the vertical buckstay, is inserted into the socket part so as to be able to slide in a vertical direction, inhibits the horizontal buckstay from being inclined, and is allowed to be fastened to the socket part. | 04-28-2011 |
20110146597 | ASSEMBLIES AND METHODS FOR SECURING A RISER BRACE - An assembly for securing a riser brace to a riser pipe includes brackets configured to engage a yoke of the riser brace and clamp bands that are configured to extend around the riser pipe and connect to the brackets. The assembly also includes a connection that connects the assembly as a unit and is configured to adjust the tightness of the assembly around the riser pipe and riser brace. | 06-23-2011 |
20110146598 | CUFF FOR BOILER TUBE ASSEMBLY AND METHOD OF MANUFACTURE - A system for retaining boiler tubes in an array includes a bracket having a contoured surface defining at least one channel, the channel being semi-cylindrical and defined by an elongated cross section having a rounded portion and two elongated legs extending therefrom to define a substantially U-shaped cross section, and a planar section located at a terminus of each leg. The system also comprises a plate connectable to at least one planar section of the bracket. A method of manufacturing a cuff for a boiler tube assembly includes bending a bracket having at least one channel therein, the channel being configured to receive a boiler tube of the boiler tube assembly; and machining a plate, the plate being configured and sized to be positioned over the channel. | 06-23-2011 |
20120079996 | Thermal Power Plant - A thermal power boiler includes a furnace enclosed by two short side walls and two long side walls, flue gas channels arranged above the furnace, a back pass and a supporting structure. The supporting structure includes a stationary bearing structure supported from below. The bearing structure includes multiple vertical pillars and a parallel main supporting beams supported by the vertical pillars, and a suspension structure, so that the furnace hangs from the bearing structure. The main supporting beams and the flue gas channels arranged above the furnace are parallel with each other and parallel with the short side walls. The main supporting beams are preferably arranged at least partially between the flue gas channels extending over the roof of the furnace. | 04-05-2012 |
20120167839 | ANTI-VIBRATION TUBE SUPPORT PLATE ARRANGEMENT FOR STEAM GENERATORS - A means of offsetting semi-circular tube support plates typically present in heat exchangers with cross flow baffles, such as axial flow economizers, utilizing the motive force of steam generator pressurization. The offset slightly flexes the tubes, thereby providing a preload which minimizes the potential for tube vibration and wear. | 07-05-2012 |
