Abstract
The expense of fabricating an annular combustor (10) for a gas turbine is minimized by providing a combustor housing (12) including a generally axially extending sleeve (14) and an annular liner (18) disposed within the housing (12) and about the sleeve (14). The annular liner (18) has concentric inner and outer axially extending walls (20, 22) spaced from the sleeve (14 ) and the housing (12), respectively, and also has a radially extending wall (24) spaced from the housing (12 ) and interconnecting the inner and outer walls (20, 22) at one end to define a combustion chamber (26). The liner (18) is spaced from the housing (12 ) and the sleeve (14 ) to define a compressed air flow path (28) extending from a radially outer compressed air inlet (30) to a radially inner compressed air outlet (32) in communication with the combustion chamber (26) axially remote from the radially extending wall (24). The annular combustor (26) is provided with a plurality of air blast fuel injectors (42, 44) for injecting a fuel/air mixture into the liner (18 ) in a generally tangential direction adjacent the radially extending wall (24). The annular combustor (10) also includes a plurality of open ende…
