A sootblower for an economizer of the type having a vertically extending cylindrical casing in which is mounted a plurality of spiral coils arranged parallel to each other in concentric relation with respect to the central vertical axis of the cylindrical casing. The spiral coils are in the form of finned tubes, the coils being disposed in closely spaced relation but providing clearance between the fins on adjacent coils. A heat exchange fluid is conducted through the spiral coils whereby the coils can extract heat from exhaust gases passing upwardly through the economizer from a boiler. The sootblower is mounted in the casing below the spiral coils and includes a pair of horizontally disposed structural tubular members arranged across the casing adjacent the bottom thereof, a vertically extending connecting pipe passing through a first one of the tubular members in concentric relation with respect to the casing, a steamline extending horizontally into the interior of the casing below the coils and terminating in an interior ball joint elbow, the upper end of the vertical connecting pipe being provided with an enlarged ball opening which is received within the ball joint elbow forming a fluid-tight fit with the ball but allowing a 360. degree. movement of the vertical connecting pipe, a horizontal arm extending outwardly from the lower end of the vertical connecting pipe, and a plurality of nozzles on the upper surface of the arm for directing jets of steam into the spaces between adjacent coils.

The present invention is an enhanced type of fin for making an enhanced serrated finned tube for use in heat exchange applications. The segments, which are formed on the fin when the fin is serrated, are enhanced either prior to serration or after serration. The enhancement consists of impressing, cutting or otherwise providing indentations into the segments, thus broadening the segments, increasing their surface area, and increasing their heat transfer capability.

A laser beam is directed toward a rotating metallic tube having a fin helically wound about and welded to its surface by a high frequency welding process. The laser beam generates heat in the tube to supplement the heat induced by resistance to electrical current flow to create a proper temperature in the tube for forge welding of the fin and tube.

The invention is a cold rolling process which converts rods of hot rolled metal into strips with width to thickness ratios as high as approximately 17 to 1. The process cools the rod between successive rolling mills and employs feed backward tension controls to direct the speed of each individual upline rolling mill in order to reduce the thermal and mechanical shock experienced by the rod as it is flattened into a strip.

The present invention is based upon the recognition that three different zones of heat transfer conditions exist on a finned tube: 1. The upstream zone (portion) of the finned tube that is initially exposed to the fluid flowing from a given location; 2. Zones that include the areas on opposite sides of the finned tube where the fluid flows around the finned tube and across (through) the fins; and 3. A zone that is located on the trailing edge of the finned tube (opposite from the first zone). The invention recognizes that the fluid flowing conditions (temperature, pressure and velocity) are different at each of the three zones. Because of this difference the invention is the use of a different fin configuration and/or geometry in each of the zones that are conducive to the heat transfer for the fluid flow condition encountered at each zone, thus increasing the heat transfer capability of the fins.
