Abstract
A burner in which steam is utilized to atomize fluid fuels such as natural gas and fuel oils. The burner includes a first tubular housing having a first outlet defined at one end; and a second tubular housing fixedly mounted within the first housing having an end which defines an exit adjacent and enclosed by the first outlet and so mounted to define an annular space between the housings. The burner further includes a plurality of fuel nozzles mounted within the second housing wherein an initial mixture of steam and a fluid fuel is formed and from which the initial mixture is emitted toward the exit and a confluence with air flowing in said annular passage so that a combustible mixture is formed; and a turbulator ring mounted within and at the exit to define a sharp-edged orifice and a narrow annular orifice.
