Turbine combustion system coupling with adjustable wear pad and corresponding assembling method

A turbine combustion system comprises a nut affixed to an outer surface of a transition impingement sleeve forward ring (50) that encircles, and is affixed to, a forward end (44) of a tubular transition impingement sleeve (45). The nut has a threaded hole (63) aligned with a hole (66) in the impinge...

Zusammenfassung:	A turbine combustion system comprises a nut affixed to an outer surface of a transition impingement sleeve forward ring (50) that encircles, and is affixed to, a forward end (44) of a tubular transition impingement sleeve (45). The nut has a threaded hole (63) aligned with a hole (66) in the impingement sleeve forward ring. A screw (68) is threaded into the nut and extends through the hole (66), and has an inner end with a wear pad (70), and an outer end with a turning tool engagement element (72). The wear pad contacts an outer surface of an aft portion of a transition piece forward outer ring (52) that is surrounded by the transition impingement sleeve forward ring (50). The rotational position of the machine screw (68) sets a radial gap (76) between the transition impingement sleeve forward ring and the transition piece forward outer ring. A corresponding method of assembling such a turbine combustion system is also provided.
