Abstract
In a gas turbine combustion system, liner stops mount a combustion liner within a flow sleeve. The liner stops are mounted on the outer surface of the combustion liner and the inner surface of the flow sleeve in a symmentrical array of liner stops. The liner stops have inclined contacting surfaces that support the liner within the sleeve, and provide rubbing contact between the two. These inclined surfaces are on a post of a male liner stop that fits into a channel of a female liner stop.
Claims8
A combustion system in a gas turbine comprising:
- a combustion liner having a longitudinal axis and defining a combustion zone, said liner having an outer surface with a coupling member extending outward from the liner;
- a combustor flow sleeve which houses and is coaxially aligned with said combustion liner, said flow sleeve having an inner surface with a mating coupling member extending inward from the flow sleeve, and
- said coupling member of the flow sleeve having a pair of inclined surfaces that are inclined relative to the longitudinal axis to engage opposite inclined surfaces on the mating coupling member of said combustion liner.
A combustion chamber in an annular array of combustion chambers in a gas turbine, where the combustion chamber comprises:
- a flow sleeve having an inner surface and a longitudinal axis;
- a combustion liner coaxially arranged within the inner surface of the flow sleeve;
- a male liner stop mounted on an outer surface of the combustion liner or an inner surface of the flow sleeve, the male liner stop having a post with opposite sidewalls, and each sidewalls inclined from a leading edge of the sidewalls to a trailing edge of the sidewalls;
- a female liner stop mounted on the inner surface of the flow sleeve or the outer surface of the combustion liner, the female liner stop having a channel to receive the post of the male liner stop, and the channel having opposite sidewalls inclined from an entrance to the channel to the end of the channel, and
- wherein the opposite sidewalls of the post of the male liner stop are in rubbing contact with the opposite sidewalls of the channel of the female liner stop and inclined relative to said longitudinal axis.
