ABSTRACT:
In order to significantly reduce the carbon produced in a combustor (10), and thus reduce or eliminate carbon buildup on combustor walls (14), a stored energy combustor (10) has a fuel discharge port (30) downstream of the combustion chamber (20). The downstream fuel discharge port (30) directs fuel into a secondary stored energy zone (24) downstream of a primary stored energy zone (22) comprised of an inlet end (16) and the combustion chamber (20) which receives an oxidant and a fuel through an upstream fuel discharge port (28) where the oxidant/fuel mixture is ignited to produce hot gases of combustion. The downstream fuel discharge port (30) is arranged to direct fuel in a manner forming a fuel film on the interior wall (14) in the secondary stored energy zone (24) such that the hot gases of combustion interact with the fuel film to cause fuel evaporation by establishing a stratified fuel annulus (54, 56). In particular, the stored energy combustor (10) is such that the hot gases of combustion interact with a cold liquid fuel film (54) on the interior wall (14) to cause fuel evaporation in the secondary stored energy zone (24) while also producing a cool gaseous fuel annulus (56) thereabout adjacent the interior wall (14) from evaporation of the cold liquid fuel film (54).
