Abstract
Official abstract text for this publication.
A nut ( 64 ) is 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 machine screw ( 68 ) is threaded into the nut and extends through the hole ( 66 ), and has a radially inner end with a wear pad ( 70 ), and a radially 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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A turbine combustion system comprising: a transition piece impingement sleeve with a forward end; an impingement sleeve forward ring affixed to and encircling the forward end of the impingement sleeve; a transition piece forward outer ring having an aft end encircled by the impingement sleeve forward ring and a forward end engaged with a downstream end of an outer wall of a combustion chamber; and a selectively adjustable radial displacement limi…
