Abstract
The invention relates to an improvement in atomizing methods and apparatus useful for combusting liquid fuel, such oil. The atomizing methods and apparatus consistently produce liquid fuel streams having vary narrow spray angles. The liquid fuel streams having very narrow spray angles can be produced even when a low liquid fuel flow rate is employed and even when a liquid fuel stream is atomized outside a liquid fuel passageway. The production of the constant narrow spray angle liquid fuel stream allows the atomizing apparatus to operate for a long period without causing fouling problems even if they are sufficiently recessed from internal openings of refractory ports defined in the furnace wall.
