[Also in Divisions F3 and F4] A nozzle system for injecting fluid into a fluid dispersion zone comprises two sets of nozzles, the nozzles of one set having different nozzle tips from the nozzles of the second set, the nozzle sets being capable of producing first the second set of nozzles being arranged alternately with one of the first set of nozzles and each of the second set of nozzles being disposed opposite one of the first set of nozzles whereby said first and second spray patterns are combined to produce a fluid dispersion in the dispersion zone. Specified nozzles are conical transversely slotted nozzles and circular nozzles. The nozzles may be arranged peripherally round the zone or in rows along at least two opposite sides thereof. More than one row of nozzles may be used, or the nozzles in a row may be staggered. The fluid may be a fuel, and the zone a combustion chamber of a furnace. The invention is described and illustrated in relation to a regenerative furnace for hydrocarbon cracking.
