Definitions

  • a fuel spray distributor comprises ejection chambers fed with fuel and ejecting fluid and the ejection chambers are arranged with their longitudinal axes converging in the general direction of fuel discharge and skewed relative to the axis of the distributor for suitable divergence of the spray.
  • This invention relates to fuel burning apparatus and more particularly to multi-jet distributors by means of which fuel is distributed in a burner by the use of an ejecting fluid which is introduced, together with fuel, into ejection chambers formed in the distributor.
  • the invention is applicable to oil fuel distributors where the fuel oil is caused by a second fluid to be distributed as an atomised spray; but it is also applicable to pulverised fuel distributors in which the ejecting fluid causes the fuel to be discharged from the distributor in spray form.
  • a spray distributor for fuels in which an ejecting fluid and the fuel are introduced into a plurality of ejection chambers, said ejection chambers are arranged with their longitudinal axes converging in the general direction of fuel discharge and in a skew disposition relative to the axis of the distributor so as to provide a desired divergence of the fuel spray.
  • a distributor in accordance with the invention it will be observed that by skew convergence of the axes of the ejection chambers a desired pattern of spray divergence may be achieved without impingement one upon the other of the spray streams issuing from the ejection chambers.
  • the temperature can be held below that level at which the surface dries and carbonisation commences.
  • the atomiser head 1 is faired-oif to present a face 2 having a comparatively small area.
  • a number of discharge orifices 3 which form the outlets for the atomising-fluid/ oil ejection chambers 4 (which in oil distributors are usually referred to as mixing chambers) which are inclined with respect to the atomiser face and to the axis of the head so that the discharge from the portings forms a skew jet.
  • Oil is supplied through the oil portings 5 which lead through oil feed ducts 6 into the ejection (mixing) chamber portions.
  • Ejection fluid is fed to the chambers 4 through ejection fluid feed ducts 7 which are coaxial with their respective chambers '4.
  • the length and diameter of the ejection (mixing) chambers are preferably characterised to promote the highest efliciency of mixing and, for convenience, may have a small arboring at the discharge orifice for calibrating purposes.
  • the inclination of the ejecting fluid jet axes is preferably used advantageously to induce rotational velocity in the ejection (mixing) with benefit to the efiiciency of the mixing process.
  • a particular feature of a distributor in accordance with the invention is its presentation, in the spray pattern, of transit paths for the passage of combustion air from the outside of the axisymmetric flame to its inside, to promote flame stability.
  • 'Distributors in accordance with the invention may be machined from any solid material capable of withstanding the wear due to flow and which has both sufficient thermal conductivity to sustain the essential rate of heat transfer and strength to support the loads due to fluid pressures.
  • thin-wall porting assemblies may be comprised of one material, for example steel, and set in a supporting matrix of another material, for example, white metal.
  • An oil fuel distributor manufactured in brass to the design illustrated, has been burned for over seventy hours without any cleaning and it is expected that it will continue to burn without fouling indefinitely or until such time as one of the orifices is blocked adventitiously. It has been established that this design of distributor is not susceptible to carbonisation reuslting from excessive face temperatures and is capable of protracted service in furnaces with very high rates of heat release in close proximity to other distributors providing similarly large flames. The distributor has proved to be superior to other two-fluid distributors and is capable of producing a well-defined compact flame of exceptional heat release for its volume (in excess of 2,000,000 B.t.u./cu. ft./hr. at 4,000 lb./hr.
  • the skew configuration by which adjacent individual jets lie in different planes without impingement of the jets one upon the other, specifically enables close clustering of orifices in a single distributor head which is necessary to realise this benefit in a practical design.
  • a distributor for spray ejection of a fuel in the group consisting of liquid fuels, pulverised fuels and combined liquid and pulverised fuels comprising a plurality of fuel feed ducts, a plurality of ejecting fluid feed ducts and a plurality of ejection chambers, each said ejection chamber being associated with at least one fuel feed duct and at least one ejecting fluid duct and said ejection chambers being arranged with their longitudinal axes converging in the general direction of fuel discharge and in skew disposition relative to the axis of the distributor so as to provide a desired divergence of the fuel spray.
  • An oil fuel distributor for spray ejection of oil comprising a plurality of oil feed ducts, a plurality of ejecting fluid feed ducts and a plurality of ejection chambers, each ejection chamber being associated with one said oil feed duct and, co-axially, with one said ejection fluid feed duct, and said ejection chambers being arranged with their longitudinal axes converging in the general direction of fuel discharge and in a skew disposition relative to the axis of the distributor so as to provide a desired divergence of the fuel spray.
