摘要：1341253 Vortex burners ESSO RESEARCH & ENG CO 19 April 1971 [6 July 1970] 26452/71 Heading F4T A vortex-type burner for the combustion of oil or gas fuel from a gun 37 with air from an inlet and plenum chamber in the burner casing 12 comprises a swirl chamber in a casing 22 for receiving a predetermined fraction of the air inlet flow and setting up a vortex with the injected fuel, and annular refractory tiles 42 and 45 shaped so as to define a uniform annular air gap 39 between them and a second such gap 40 between the tile 45 and a support plate 49, the remainder of the inlet air being directed through these gaps 39 and 40 to shape and contain the flame without the use of a combustion chamber and to aid combustion by creating turbulences to recirculate hot gases to the combustion zone. The inlet air may be preheated or ambient and its speed of flow through gaps 39 and 40 can be changed by adjusting the gap widths by means of bolts, which air flowing in the gaps must comprise at least half of the inlet air. In a modification of this construction the upper surface 51 of tile 45 and the support plate 49 slope inwardly so that gap 40 is inclined to the horizontal. In an alternative embodiment only one air gap is provided which is formed between parallel surfaces of two annular tiles. The burner casing is lined with block insulation and a pilot system may be incorporated. The burner is described as being mounted on a furnace floor 11 or wall.
