FURNACE BAFFLE.
Application filed July 18, 1927.
My invent-ion relates to furnace battles, particularly to the vertical, or SGll'll-VGltlCll batlles which are used in connection with water tube boilers. The object of my invention is to provide a bafiie of the hind above referred to which will be simple in construction, inexpensive to manufacture, and will not interfere with the renewal of boiler tubes, and'one which will serve to support the tubes to which it is applied, thus preventing their sagging under the influence of the heat applied thereto.
In the accompanying drawings, which illustrate one form of baflie made in accord- 5 ance with my invention, Figure 1 is a vertical cross section; Figure 2is a vertical longitudinal section on a reduced scale; Figure 3 is an enlarged sideview of the upper end of one of the bars; Figure 4- is a view similar to Figure 3 but looking at the opposite side; Figure 5 is an enlarged section taken on the line 5 5 of Figure 3; and Figure 6 is an enlarged section taken on the line 6-6 of Figure 1.
10 indicates the boiler tubes, 11 the furnace side walls. 1.2 the upper horizontal baflie, and 13 the lower horizontal battle. All these parts may be of any usual and well known construction.
My improved vertical baflle is composed of a number of battle bars 14, each provided in its sides with a number of semi-circular recesses 15 adapted to fit around the boiler tubes 10. In case the baffle of the semivertical type; that is, isinclined to the axis of the boiler tubes in place of being perpendicular thereto as shown, these recesses 15 will of course be of semi-elliptical form. The center of each of the baffle bars is preferably provided with a strengthening rib 16. On one edge of each of the bars is a lip 17 adapted to overlap the edge of the adjacent bar and thus form a tight joint between the various parts of the bafile. The upper end Serial No. 206,430.
of each of the bars is provided with a bolt hole 18, preferably somewhat elongated, as shown in Figures 3 and 4, so to allow for expansion and contraction of the parts owing to the heat of the furnace. Bolts 19 passing through these openings 18 secure the batlle bars to a cross bar 20 preferably in the form of an angle iron. The main portion of the baltle is comprised of bars of similar size and shape. In order to complete the baflle, however, it is necessary to provide short bars 21 at one end, which bars differ from bars 14 only in their length, while at the opposite end short bars 22 are bolted to a vertical supporting bar 23 and consequently the angle of the supporting end is the reverse of that in the other bars.
In inserting the bars in position they are passed down between the boiler tubes in flat position and turned through an angle of 90 degrees to bring them into the position shown in Figure 1, when they may be bolted to the supporting bars 20 and 23 to complete the baffle.
It will be evident that my battle does not interfere with the removal of an injured boiler tube and that it acts as a support for the tubes to prevent their sagging.
Having fully described my invention,
what I claim as new and desire to secure by Letters Patent of the United States is: V
In a device of the class described, the combination with the water tubes of a boiler, of bafile bars inclined to the perpendicular, said bars varying in length and each provided on both edges with recesses for engaging the tubes, a horizontal supporting bar to which a part of said bars are secured, and a vertical supporting bar to which the remainder of said bars are secured.
In testimony whereof, I hereunto ailix my signature, this 16th day of J uly, 1927.
LEO WOERNER.
