An apparatus and a method for mixing and atomizing a hydrocarbon stream is disclosed. The apparatus comprises of an inner conduit having a first inlet for receiving the hydrocarbon stream, and a second inlet for receiving a primary dispersion stream. The inner conduit produces a primary mixture comprising the hydrocarbon stream and the primary dispersion stream. The apparatus further includes an outer conduit having a third inlet for receiving a secondary dispersion stream. Further, said inner and outer conduits together define an annular passage. The distal end of the annular passage defines a second set of orifices for allowing the secondary dispersion stream flowing there-through to come in contact with the primary mixture and thereby dispensing the secondary mixture so obtained through an outlet.

Nozzle apparatus for producing a liquid jet are disclosed. An example nozzle apparatus includes: (a) an outer nozzle housing defining a cavity and having an outlet defined at an apex of the cavity, (b) a cylindrical sidewall coupled to a base of the nozzle housing, where the cylindrical sidewall defines a plurality of arch-shaped voids and (c) an inner housing coupled to the outer nozzle housing, where the inner housing has a first end and a second end, where at least the first end of the inner housing is arranged within the cavity of the outer nozzle housing, where the inner housing defines a through-hole that is arranged concentric with the outlet of the outer nozzle housing.

Spraying apparatus 10 includes: inner lid 13; outer lid 14; and gas-liquid mixing section 15 between inner lid 13 and outer lid 14, wherein a liquid is introduced into gas-liquid mixing section 15 from a position upstream and proximate outer lid plate 14a of outer lid 14, and a gas is introduced into gas-liquid mixing section 15 from an opposite position, the liquid is atomized in gas-liquid mixing section 15 by the liquid impinging with the gas and transforming into a gas-liquid mixed fluid, and advancing to spouting portion 16 as the gas-liquid mixed fluid is circulated along outer lid plate 14a of outer lid 14 in gas-liquid mixing section 15.

The invention relates to a new atomizing device with improved droplet formation. Smaller droplets are formed with increased micronized volume throughput, wherein high volumes of air are fed to a liquid sprayed from a liquid nozzle. High volume ratios result in mean free path between droplets being conveyed so as to minimize collisions and to prevent aggregation of the droplet.

A steam atomizing liquid spraying system which in the preferred embodiment includes a spray nozzle assembly having a central liquid passageway for coupling to a liquid supply and a plurality of spray nozzles each removably mounted in the nozzle body and having a respective central steam passage communicating with a steam supply. The spray nozzles each further have a plurality of circumferentially spaced liquid accelerating passages that communicate with a respective angled passage of the nozzle body which in turn communicates with the central liquid supply passageway for directing liquid into the central steam passage of the spray nozzle for interaction with steam directed through the central steam passage and atomization of liquid discharging from the spray nozzle. In an alternative embodiment, a single spray nozzle insert is utilized.
