<p>A coupling apparatus for connecting a combustor (10) to a transition (30) in a gas turbine is provided. The coupling apparatus comprises a transition cylinder (20) attached to the discharge end (12) of the combustor (10), a cylinder flange (29) formed on the downstream end (28) of the transition cylinder (20), a transition (30) having an upstream end (32) on which a transition flange (31) is formed, and a plurality of nut and bolt combinations circumferentially spaced about the periphery of the flanges for maintaining the transition cylinder (20) in tight engagement with the transition (30) when the cylinder flange (29) mates with the transition flange (31). In a preferred embodiment, the cylinder flange (29) further comprises a spigot lip (48) and the transition flange (31) further comprises a recess (52) for receiving the spigot lip (48) so as to effect a tight spigot fit when the cylinder flange (29) mates with the transition flange (31).</p> |
