Patent number: 8387473Abstract: A temperature sensing sootblower that may be configured as a modification to an existing sootblower or a specially constructed sootblower that, in addition to its normal soot blowing functions, has the capability to measure the flue gas, lance tube, and/or cleaning fluid temperatures. One or more thermocouples or other temperature measuring devices are carried by the sootblower lance tube that is inserted into the boiler. This allows for the temperature of the flue gas, lance tube, and cleaning fluid to be measured as the sootblower lance tube is inserted into and retracted from the boiler. Multiple temperature measuring devices may be located on the sootblower lance to measure the temperature across heat transfer surfaces and at different locations along the lance tube. A data transfer device transmits the temperature measurements from the rotating thermocouple to a non-rotating data acquisition unit for use in boiler cleaning and other operations.Type: GrantFiled: January 21, 2011Date of Patent: March 5, 2013Assignee: Clyde Bergemann, Inc.Inventors: Charlie L.

Patent number: 7367079Abstract: An integral packing housing and packing material unit; a method for packing replacement, boiler cleaning; and a method for maintenance of a desired boiler output rating. The integral packing unit includes a housing for removably holding a sacrificial packing material that is configured to form a steam seal between a sootblower steam tube and lance spindle when the packing unit is installed in an operative position in association with the steam tube and the spindle and the packing material is loaded by applying compression to the packing material. A compression unit is typically coupled to the housing unit to apply such compression to load the packing material while the packing unit is installed in the operative position. The packing unit may also includes a detent mechanism, such set screws, for unloading the packing material to facilitate installing the packing unit on, and removing the packing unit from, the operative position.Type: GrantFiled: July 2, 2003Date of Patent: May 6, 2008Assignee: Clyde Bergemann, Inc.Inventors: Hans Schwade, Bruce Townsend, Michael W.

Patent number: 7185594Abstract: A combustion air system for a recovery boiler is described in which multiple levels of secondary and tertiary combustion air ports each have an even number of ports, with the ports on opposing walls interlaced. The air system lends itself equally well to front/rear wall or sidewall applications and is especially beneficial for rectangular boilers. The air system features large and small-scale horizontal circulation zones superimposed on each other and the ability to adjust the angle of the air jets. Additional features include port dampers for the starting burners and system control based on kinetic energy.Type: GrantFiled: July 2, 2004Date of Patent: March 6, 2007Assignee: Clyde Bergemann, Inc.Inventors: Daniel R.

Patent number: 7026598Abstract: A method for controlling the positioning of a stream of pressurized fluid against a surface zone of a stream generator to clean contaminants. The coordinates of a plurality of points of the surface zone to be cleaned are first determined. The coordinates are measured with respect to a fixed coordinate system with origin point at the location where the lance water cannon penetrates the cannon wall of the steam generator. The determined boundary points are converted into corresponding angles with respect to the horizontal plane and the cannon wall. These angles are then used directly to control the position of the lance with respect to the fixed coordinate system. The stream of pressurized fluid is directed against the surface zone in a predetermined pattern by monitoring and controlling the angle of the lance through axial resolvers.Type: GrantFiled: February 20, 2002Date of Patent: April 11, 2006Assignee: Clyde Bergemann, Inc.Inventors: Hans Schwade, M.

Patent number: 6988468Abstract: An indexing style Automatic Port Cleaner for cleaning furnace combustion air ports employs multiple cleaning tips and rods enclosed substantially in a furnace windbox. An extension bar enclosed substantially in a furnace windbox to which the cleaning rods are attached with the extension bar carries the cleaning rods and tips in a translating and indexing motion. An extension bar is supported by two fulcrum rods and in turn supported by two fulcrum tubes and two fulcrum housings, the fulcrum housings being supported by a faceplate and fixed relative to the combustion air ports. The fulcrum rods translate relative to the fulcrum tubes while the fulcrum tubes rotate relative to the fulcrum housings. A linear actuator is disposed to create a reciprocating translating motion of the fulcrum rods, extension bar, cleaning rods, and cleaning tips. Indexing creates rotation of the fulcrum tubes, fulcrum rods, extension bar, cleaning rods, and cleaning tips, in a reciprocating fashion about the fulcrum housings.Type: GrantFiled: June 14, 2004Date of Patent: January 24, 2006Assignee: Clyde Bergemann, Inc.Inventors: Dan Higgins, Ken Pingle, Todd Hill, Mike Kranda, Jim Payne, Alan Clother

Patent number: 6581549Abstract: A cardon joint is provided for mounting in a wall of a boiler to accommodate a sootblower lance and to allow the lance to be manipulated with respect to the boiler wall. The cardon joint includes a wall box having a central opening. An outer ball having a substantially spherical outer surface and a central bore is mounted for axial rotation about a first axis within the central opening of the wall box. An inner ball having a substantially spherical outer surface and a central bore is mounted for axial rotation about a second axis within the central bore of the outer ball. The first and second axes are mutually orthogonal and the central bore of the inner ball is sized to accommodate the lance of a sootblower. As the lance is manipulated to clean an opposite wall of the boiler, the inner and outer balls rotate about their axes to accommodate the manipulation.Type: GrantFiled: August 31, 2001Date of Patent: June 24, 2003Assignee: Clyde Bergemann, Inc.Inventors: Michael W.
