LIQUID FUEL ATOMIZER The invention relates to atomizer, more particularly for atomizing liquid fuels for combustion.
According to one aspect of the invention an atomizer consists solely of an outer, annular liquid nozzle chamber which converges towards an annular outlet therefrom, a coaxial, inner gas nozzle chamber which converges towards an annular outlet therefrom and a rigid annular deflector member positioned coaxially with respect to said outlet openings and extending at least from said outlet openings to a point downstream of said outlet openings, the deflector member also having a gas bleed duct leading to a further deflector arranged, in use, to deflect a gas stream across the outer end face of the deflector member.
Preferably the gas bleed duct and arrangement of further deflectors are such as to provide said gas stream at approximately one third of the operating gas pressure of the atomizer.
The diameter of the further deflector may be approximately one half the diameter of the outer end face of the deflector member.
The further deflector may comprise an insert which is mounted in a central aperture in the deflector member and may be spaced between 0.004 and 0.007 inches from the outer end face of the deflector member.
The foregoing and further features of the invention may be more readily understood from the following description of a preferred embodiment thereof, by way of example, with reference to the accompanying drawing, which is a perspective view, part cut away, of an atomizer.
Referring now to the drawing there is shown an atom izer which comprises a distributor member 11 formed with an outer circumferential ring of axial liquid feed passages 12 and an inner circumferential ring of axial gas feed passages 13. An inner surface 14 of member 11 is screw threaded to receive a coaxial feed pipe (not shown) to supply gas to passages 13 and liquid to passages 12 with ring seals 15 and 16 interposed therebetween.
The gas feed passages 13 lead into a convergent annular nozzle chamber 17 which is defined by a frustoconical divergent surface 18a of a deflector member 18 which is screw threaded into a central aperture in the distributor member 11 at the end remote from the feed thereto.
The liquid feed passages 12 lead into a convergent annular nozzle chamber 19 formed by a cylindrical extension lla and the inner frusto-conical convergent surface 200 of an annular member 20 which is screw threadedly engaged with the outer surface of member 11.
A further deflector 21 is screw threadedly engaged in a central aperture in deflector member 18 so as to have a central axial passage 22 in registry with a central axial through passage 23 of deflector member 18. The further deflector 21 is also formed with radial metering passages 24 leading from passage 22 to an annular space 25 between members 18 and 21. The inner surface of the outer portion of further deflector 21 is arranged to be spaced from the outer surface of deflector member 18 by between 0.004 and 0.007 inches. The diameter of the outer portion of further deflector 21 is arranged to be approximately one half the diameter of the outer surface of deflector member 18.
In operation compressed gas is fed through feed passages 13 to chamber 17 where it is emitted at sonic velocity to flow along the outer surface of deflector member 18. As the pressure of the gas decreases along deflector member 18 its velocity increases to supersonic. When the gas approaches the curved portion of deflector member 18 the gas pressure increases and the velocity decreases so producing shock waves. Liquid to be atomized is fed through passages 12 to chamber 19 and then is emitted as a film into the gas being emitted from chamber 17. The liquid film is accelerated by the gas and maintained out of contact with deflector member 18 by the gas so effectively forming a divergent nozzle between deflector member 18 and the liquid film. The acceleration of the liquid film reduces its thickness and causes shearing. The pressure fluctuations at the culmination of the supersonic velocities reached by the gas which produce the shock waves cause vibrations of the liquid layerand further shearing and break up occurs in a plane normal to the horizontal shearing.
Gas is also fed through passages 23, 22 and 24 respectively into annular space 25 and thence between member 21 and 18 to provide a continuous gas stream across the face of deflector member 18. The size of metering passages 24 and the location of member 21 are arranged to be such that the gas pressure of the stream is approximately one third of the operating gas pressure of the atomizer.
This gas stream applied across the face of deflector member 18 forms no part of the atomization process but prevents build up of carbon or other deposits on the face of deflector member 18 when the atomizer is being used in a fuel firing operation. Without the provision of the further delfector 21 the deposits could build up to project beyond the periphery of member 18 and impair the operating efficiency thereof.
