Abstract
In order to significantly reduce the carbon produced in a combustor, and thus reduce or eliminate carbon buildup on a combustor wall (14), a stored energy combustor (10) has a fuel injector (28) in a tubular extension (16) of a vessel (12) leading to a combustion chamber (20). The fuel injector (28) has a discharge end (60) upstream of a plane defining a point of entry (32) into the combustion chamber (20) for directing an annulus of fuel (26) toward the combustion chamber (20), and an oxidant inlet port (24) is also provided upstream of the combustion chamber (20) for directing oxidant into the combustion chamber (20) through the tubular extension (16) in surrounding relation to the fuel injector (28) which is concentric with the longitudinal axis (22) of the vessel (12). In addition, the stored energy combustor (10) includes an air swirler (34) upstream of the combustion chamber (20) and the discharge end ( 60) of the fuel injector (28) for swirling oxidant in the tubular extension (16) which directs oxidant in a swirling annulus (46) into the combustion chamber (20) outwardly of the annulus of fuel (26).
