摘要： A fuel-fired air heating furnace is provided with NOx reduction apparatus associated with a plurality of combustor tubes forming a portion of the furnace heat exchanger section. Inshot-type fuel burners are spaced apart from and face the open inlet ends of horizontal combustion sections of the combustor tubes. The NOx reduction apparatus includes a plurality of NOx reduction members formed from a metal rod material, and a mounting plate having a row of spaced apart pairs of mounting holes therein. Each NOx reduction member has an elongated, generally U-shaped configuration, with a closed inner end, an open outer end, and a spaced pair of corrugated leg portions extending between such inner and outer ends. The NOx reduction members are installed in a parallel relationship on the mounting plate, with their closed ends facing in the same direction, by resiliently deflecting the leg portions of each member toward each other, inserting the outer leg ends in one of the mounting plate hole pairs, and then releasing the legs. With the NOx reduction members secured to the mounting plate in this manner, they are simultaneously inserted closed ends first into their associated combustor tubes, and the mounting plate suitably supported adjacent the combustor tube inlets. The burners are then positioned to inject flames into the combustor tubes with the NOx reduction members positioned therein to operatively intercept the incoming burner flames.

摘要： The four metal panel portions of an air conditioning unit roof curb have spaced sets of inwardly projecting lanced portions positioned adjacent their ends and defining tab-receiving slots. With the panel portions in a rectangular assembly orientation, specially designed drive cleats are used to lock the contiguous ends of the panel portions together at the corners of the curb. Each cleat has spaced pairs of tabs which, when the cleat is downwardly driven into place on a corner section of the curb, sequentially enter vertically successive pairs of slots in the contiguous panel end portions at the corner. In this manner, only one tab pair and one slot pair need to be aligned with one another before the cleat is driven into place to lock the two contiguous panel end portions to one another, the initial tab pair/slot pair alignment serving to automatically align the successive tab and slot pairs as the cleat is driven home. A pair of the tabs on each drive cleat have dimples thereon which function as detent structures that releasably lock the cleat tabs in their panel slots and thereby releasably retain the drive cleat in place on the assembled roof curb. In an alternate embodiment of the drive cleats, side halves thereof are formed integrally with ends of the panel portions, with the tabs of the integrally formed cleat halves being sequentially insertable into the tab-receiving lance slots of adjacent panel end portions.
