Abstract
A burner operative to inject fuel and a portion of the amount of air required for stoichiometric combustion as a core into a combustion zone and the balance of the air required for substantially stoichiometric combustion is introduced coaxially around the core to form an air jacket. The burner includes a central fuel delivery pipe, a first coaxial atomizing air delivery pipe and a second coaxially surrounding air delivery pipe. The central fuel delivery pipe terminates in an outer conical surface and the first coaxial air delivery pipe terminates in a spaced coaxial inner surface and a shaped transverse outer surface for shaping the central fuel-rich flame core. The second coaxial air delivery pipe delivers an air jacket to form the fuel core and additional air is delivered coaxially around a baffle assembly and in a direction generally parallel to the core for additional flame shaping.
