Abstract
A weldless connection system for U-beam particle separators is provided in which one end of each U-beam is provided with sides and a back that are separated from each other forming tabs. The tabs may be bent, or folded, about 90.degree. inward toward the channel formed by the U-beam. The back tab may be twice as long as the side tabs, and the extra half length of the tab can be folded about 180.degree. back at the back of the U-beam in a double thickness. Each tab has a hole therethrough. The double-length back tab has two holes; one hole is provided through each half. When the tabs are bent inward, the holes align. A bolt and washer placed through the aligned holes may be used to secure the tabs, and thus the U-beam, to a furnace roof structure. An alternate embodiment of the invention is provided in which only the sides of the U-beam form tabs which extend past the bottom of the U-beam.
