20090265935 | Method for assembling a steam generator - A method for assembling a steam generator includes parallel assembly of the boiler framework and preassembly of assembly modules, and hoisting of the assembly modules into the boiler framework. The outer roof section of the boiler framework roof is then assembled. The inner roof section and the internal components are assembled simultaneously with assembly of the boiler wall in the upper section of the steam generator. The segments of the external support pipes are mounted into the assembly modules and subsequently connected at their module joints the external support pipes are mounted in the final position in the outer roof section. The buckstays and the header tie bars are mounted headers to the boiler wall or to the external support pipes. The auxiliary steel structure of the assembly modules the suspension equipment of the curtain walls are dismantled. | 10-29-2009 |
20100269345 | MEMBRANE SEAL FOR WATER HEATER TANK SPUDS - A method of manufacturing a water heater includes the steps of providing a water heater tank having an interior and an exterior, the tank also including a first aperture communicating between the interior and exterior, providing a spud having an internally threaded aperture and placing a membrane between the spud and the tank such that the membrane covers the first aperture. Thereafter, the method also includes the steps of welding the spud and the membrane to the tank, and thereafter forming a second aperture in the membrane so that the threaded aperture of the spud communicates with the interior of the tank via the first and second apertures. | 10-28-2010 |
20110094105 | Retrofit Method for Pulverized Coal Boiler - A method for retrofitting a pulverized coal boiler in an air combustion boiler system is disclosed, which has a plurality of burners over a plurality of stages along the vertical direction on a wall surface of a furnace of the pulverized coal boiler and an after-air port for introducing air for two-stage combustion located above the burners to retrofit into a two-stage combustion pulverized coal boiler in an oxyfuel combustion boiler system. | 04-28-2011 |

20130097863 | Boiler Tube Clamp and Method of Using Same - A boiler tube clamp including a first portion having a first substantially U-shaped midsection with a first inner surface configured for receiving and pressing against one side of a boiler tube, a first hinge member arranged on one end of the first midsection, and a threaded bolt hingedly attached to the other end of the first midsection, and a second portion having a second substantially U-shaped midsection with a second inner surface configured for receiving and pressing against the other side of the boiler tube. The clamp further includes a second hinge member arranged on one end of the second midsection and hingedly connected to the first hinge member so that the first inner surface and the second inner surface close toward one another. An open slot is arranged at the other end of the second midsection configured for detachably receiving the threaded bolt. A lip extends radially out from an outer surface of the second midsection and arranged adjacent to an edge thereof. A jackscrew extends through the lip for adjusting the distance a boiler tube contained by the clamp extends into a boiler through a boiler header. | 04-25-2013 |
20150040398 | FLAT BAR AND METHOD OF MAKING SAME - A method of forming a flat bar is provided. A tube is provided having an inside surface and an outside surface. The outside surface of the tube can be clad with a nickel or stainless alloy material. A helix shaped strip can be cut from the tube. The helix shaped strip can be uncoiled to form an uncoiled strip, and the uncoiled strip can be straightened and flattened to meet mill standards. | 02-12-2015 |
