Multi-flame fuel burner for liquid and gaseous fuels

Claim 1

A multi-flame air-atomizing fuel burner system comprising a plurality of air-atomizing nozzle means for using primary gas under pressure to disperse fuel, each of said air-atomizing nozzle means including a substantially vertically oriented, open ended atomizer housing, each of said housings having an aperture through which said primary gas is expanded to disperse said fuel, means for delivering liquid fuel to said atomizer housing of each of said air-atomizing nozzle means adjacent said aperture, means for delivering gaseous fuel to said atomizer housing of each of said air-atomizing nozzle means adjacent said aperture, means for selecting the type of fuel delivered to said air-atomizing nozzle means, means for delivering primary gas under pressure through said aperture of each of said air-atomizing nozzle means to disperse one of said fuels so that the dispersed fuel may be ignited in the presence of secondary air to produce a combustion flame, said air-atomizing nozzle means being spaced apart and arranged in a pattern to provide cross-ignition from a single ignited nozzle means, and flame spreader means located downstream of each of said air-atomizing nozzle means in the gaseous or hydroxyl type combustion zone of a combustion flame for stabilizing and shaping said combustion flame.
