ABSTRACT:
A fuel burner diffuser comprises a frustoconical support fitted at its smaller diameter end to a fuel burner nozzle from which fuel is emitted in a conical stream. A plurality of series of gas jets are carried by and spiral about the support for introducing combustion-supporting gas into the fuel stream. The jets are mounted on the support in such manner that gas passing through the jets is substantially perpendicular to the longitudinal axis of the fuel stream so as to facilitate penetration of the fuel stream by the gas. Those jets which are substantially diametrically opposed to one another are circumferentially offset so as to avoid diametrical confrontation for the purpose of promoting better mixing of the fuel and gas. The cross sectional areas of the jets increase in a direction away from the fuel burner to enable a greater quantity of gas to be supplied to the fuel as the cross sectional area of the fuel stream increases.
