Patent ID: 7172733

Claim:
A device for atomization and injection of a hydrocarbon batch into a reaction chamber, said device comprising: an entry and mixing chamber ( 5 ) having a circular part ( 9 ), a tube ( 8 ) inside chamber ( 5 ) for introduction of a liquid hydrocarbon, and a conduit ( 18 ) for introduction of an atomization gas into said circular part ( 9 ) of chamber ( 5 ), a Venturi tube ( 6 ) having a convergent part ( 10 ) connected to circular part ( 9 ), of chamber ( 5 ), a throat ( 13 ) connected to convergent part ( 10 ), and a divergent part ( 14 ), connected to said throat ( 13 ), said divergent part ( 14 ) also being connected to a hemispheric tip ( 7 ), said tip having a rectangular slit ( 16 ) cut along a diameter of the tip through which a liquid hydrocarbon mixture in a state of droplets, and atomization gas, can be injected into a reaction chamber, said slit ( 16 ) having an opening angle alpha along the largest dimension of said rectangle of 100Â°â€“115Â°.
