    • An adjustable gas nozzle has a nozzle body including a passageway therethrough opening into a first orifice at one end and an internal sealing surface adjacent thereto. A threaded internal surface is formed at a second end of the nozzle body. A conduit connected to a source of gas at one end having external threads adjacent a second end is threadably receivable within the second,end of the nozzle body and is moveable between the first and second alternative positions relative to the nozzle body. Integral radial ribs are formed externally about the conduit between the external threads and the second end of the conduit and are engageable with the internal surface of said nozzle body between the sealing surface and the threads. The radial ribs on the exterior of the conduit have a larger diameter than the internal diameter of the interior wall of the nozzle body and is of a harder material so that deformation occurs in the wall resulting in a tight seal when the nozzle and the conduit are coupled. A flow adjusting member is supported within the conduit and is moveable toward and away from the orifice of the nozzle body as the nozzle body is threadably moved about the conduit. The adjustment member has an interior passageway which communicates the conduit with the orifice of the nozzle body and has an external surface for cooperatively engaging the sealing surface of the nozzle body in one alternative position and is spaced therefrom in a second alternative position. The flow of gas through the nozzle body orifice varies depending upon which alternative position is selected.
    • 可调节气体喷嘴具有喷嘴主体,该喷嘴主体包括通向其中的通道,其在一端穿入第一孔口和与其相邻的内部密封表面。 螺纹内表面形成在喷嘴体的第二端。 连接到一端的气体源的导管具有与第二端相邻的外螺纹的螺纹可接收在喷嘴本体的第二端内,并且可相对于喷嘴体在第一和第二替代位置之间移动。 整体的径向肋在外部螺纹和导管的第二端之间的导管外部形成,并且可与密封表面和螺纹之间的所述喷嘴体的内表面接合。 导管外部的径向肋具有比喷嘴体内壁的内径更大的直径,并且是较硬的材料,因此在壁上发生变形,导致当喷嘴和导管为 再加。 流道调节构件被支撑在导管内,并且当喷嘴主体绕导管螺纹移动时,流动调节构件能够朝向和远离喷嘴体的孔口移动。 调节构件具有内部通道,该内部通道将导管与喷嘴体的孔连通,并且具有外表面,用于将喷嘴体的密封表面协调地接合在一个替代位置,并且在第二替代位置与其间隔开。 通过喷嘴主体孔口的气体流根据选择的替代位置而变化。

    • A premixed gas burner has an elongated hollow burner body (12) including a burner deck (26) formed by a multiplicity of burner ports (28) about a small sector of the body. The burner body is closed at one end and an elongated distribution tube (30) is received within the body through and extending out the other end. The end (32) of the distribution tube extending out of the burner body has an inlet into which a mixture of gas and air may enter, the opposite end of the distribution tube being closed. A series of directional ports (38) formed between louvered slats (40) adjacent the closed end and spaced from the inlet arc formed along a small sector of the distribution tube and directs the mixture of gas and air back toward the inlet end. The sector of the distribution tube in which the ports are formed is substantially 180° from the sector of the burner body in which the deck ports are formed. The construction provides good mixing, and substantially prevents flashback by having high velocity throughout the burner, and good distribution without a high pressure drop.
