Tie means employable for purposes of accomplishing the tying together of tubes of a superheater platen assembly. The subject tie means is particularly suited for use in those applications wherein a need exists to effect the tying together of tubes, which bear a tangential relationship to each other. The subject tie means comprises a multiplicity of cooperating tie members that are suitably affixed such as by being welded thereto, to the pair of tubes that the tie means is intended to tie together. More specifically, the multiplicity of tie members includes a first pair of tie members that is affixed to a first one of the pair of tubes and a second pair of tie members that is affixed to the second one of the pair of tubes. Each of the multiplicity of tie members is essentially L-shaped in configuration with the first pair of tie members being oriented so as to each have a portion thereof, which projects inwardly, while a second pair of tie members is oriented so that each of the tie members has a portion thereof, which projects outwardly, whereby the inwardly projecting portions of the first pair of tie members are supported in sliding engagement with the outwardly projecting portions of the second pair of tie members thereby to effect the tying together of the aforesaid pair of tubes through the interengagement of the respective projecting portions of the first and second pairs of tie members.

An improved design for square cornered ductwork (10) particularly suited for use in those applications requiring ductwork capable of resisting pressures of 40" to 50" water gauge or higher, and wherein such pressures in turn produce end reaction loads that exceed two kips in magnitude. The subject square corner ductwork (10) includes a first member (12), a second member (14) having a width substantially equal to that of the first member (12), a third member (16), and a fourth member (18) having a width greater than that of the third member (16). The first member (12) and the second member (14) each lie in a plane that extends parallel to that of the other. The third member (16) and the fourth member (18) each lie in a plane that extends parallel to the other, and perpendicular to the plane of each of that of the first member (12) and the second member (14). The first member (12) is secured to the third member (16) by means of a first weld (20) recognizable as a structural weld; and to the fourth member (18) by means of a second weld (22) recognizable as a structural weld. The second member (14) is secured to the third member (16) by means of a third weld (24) recognizable as a structural weld, and to the fourth member (18) by a fourth weld (26) recognizable as a structural weld.

A short-stroke steam lance is reciprocated through an opening in a furnace wall. A section of the lance has an extended spiral groove engaged by a protuberance from a supporting framework to force the lance to reciprocate when the lance is rotated by a motor. The steam to the lance is supplied when its valve is actuated by the lance moved into its extreme forward position.

A duct, presumably that of a utility boiler or the like, has a frame mounted on its internal walls. Parallel louver blades are mounted in the frame and linked for simultaneous actuation to move the louver-blades between a first position where they seal the frame opening against the flow of gaseous fluid and a second position where they permit the relatively free flow of gaseous fluid through the frame. Bearings for the louver shafts are mounted external the duct in which the frame is mounted and a truss is attached to the upstream and downstream edges of the frame to insure dimensional stability under the stress applied to the duct by the varying pressure and temperature of the gaseous fluid passing through the duct.

A steam generator having a coal fired furnace including water cooled walls, and having a hopper bottom. A plurality of steel struts are provided which extend between the furnace walls at a level at or above the top of the hopper bottom, and the furnace inlet ring header located at the bottom of the hopper, so that the unit can be bottom supported. The steam generating tubes extending upwardly out of the ring header and forming the furnace walls each contain a bend therein, so as to be flexible enough to accommodate differential thermal growth of the struts relative to the adjacent furnace walls during transient temperature occurrences.

A removable seal for interconnecting passageways (10, 12) that move relative to each other. A liquid containing trough (28) is secured to one of the passageways, preferably the lower, and it has floated in it a curtain member (40) which moves in accordance with the level of liquid in the trough. This member (40) extends from the trough (28) and sealingly engages the other passageway when in an upper position but is spaced therefrom when in a lower position. This construction is especially suitable for sealing an ash hopper (12) to the lower end of a furnace (10).
