Definitions

  • a supply system for burners adapted to consume an emulsion with water of light hydrocarbons comprises in known manner, a water-supply intake, a hydrocarbon supply, a mixer for Water and fuel, a high-pressure pump for sending said emulsion through an injection circuit to the injector of said burner, said supply system further comprising a dosing device for the injected water located on the water-supply circuit to said mixer, a first electrovalve and a non-return valve arranged at the input of the water-supply circuit, in front of said dosing device, a second electro-valve on the injection circuit, and a branch circuit connected on the injection circuit between the outlet of said high-pressure pump and said second electro-valve, said branch circuit being provided with a third electro-valve.
  • the present invention relates to burners for light bydrocarbons such as domestic fuel oil for example, which can be utilized in industrial or domestic heating installations and which use an emulsion of water and hydrocarbon as the fuel.
  • light bydrocarbons such as domestic fuel oil for example
  • the present invention has for its object a supply system for burners of light hydrocarbons consuming an emulsion of water and hydrocarbon and compising in known manner a water intake, a hydrocarbon supply, a mixer of water and hydrocarbon which produces the emulsion to be burnt, together with a high-pressure pump for sending the said emulsion to the injector of the burner.
  • the supply system forming the object of the present invention is essentially characterized in that it comprises, in combination:
  • a dosing device for the injected water located on the supply circuit of the water to the mixer;
  • a first electro-valve and a non-return valve mounted on the inlet of he water-supply circuit, in front of the dosing device;
  • the first and second electro-valves are closed and the third is opened.
  • the dosing device utilized for injecting the desired quantity of water into the mixer is a drop-by-drop feed of known type, for example of the high-pressure type similar to those generally used as oil distributors for the lubrication of shafts of rotating machines.
  • the light hydrocarbon employed is domestic fuel which comes in through the pipe 3.
  • the water used to produce the fuel emulsion passes into the system through the conduit 4 after having been filtered and, if necessary, expanded to a pressure valve compatible with the installation described.
  • a non-return valve 5 On the water-intake circuit 4 there are successively mounted a non-return valve 5, a first electro-valve 6 which is normally closed, and a filter-box 7.
  • a conduit 8 connects this box 7 to the dosing device 9 constituted according to the invention by a drop-by-drop over-pressure feed of a conventional type per se.
  • This drop-by-drop overpressure feed can have its flow-rate regulated by a screw 10.
  • the mixer 11 comprises a conduit 12 connected to the dosing device 9 and delivering directly at 13 into the inlet fuel conduit 3.
  • the conduit 14 resulting from the combination of the conduits 12 and 13 delivers into the highpressure pump 15 equipped with its pressure-gauge 16.
  • the outlet 17 of the high-pressure pump communicates on the one hand with the conduit 18 connected directly to the injector of the burner (not shown in the figure) and on the other hand to a branch conduit 19 returning to the fuel-oil reservoir (not shown in the figure).
  • the conduit 18 is provided according to the invention with a second electro-valve 20, which is normally closed, and the branch circuit 19 is provided with a third electro-valve 21 which is normally open.
  • the three electro-valves 6, 20 and 21 are at rest, namely in their normal position.
  • the pump 15 is put into operation and sucks-in the fuel through the pipe 3, delivering it through the third electro-valve 21 (which is open) through the branch circuit 19 to the tank.
  • This precirculation of the pure fuel has for its object to eliminate the possible remainder of a previous emulsion of water and fuel which may have remained in the burner and in the various conduits, and thus to permit the said burner to be lighted with pure fuel, which renders the operation much more reliable and much easier.
  • a supply system for a burner for light hydrocarbons utilizing an emulsion of water and light hydrocarbon comprising a water intake, a light hydrocarbon supply, a mixer of water and light hydrocarbon, a high-pressure pump forcing said emulsion through an injection circuit towards the injector of the burner a closing device for the injected water, located in the supply circuit of water to said mixer;
  • branch circuit connected in the injection circuit between the outlet of said high-pressure pump and said second electro-valve, said branch circuit including a third normally closed electro-valve open during lighting of the burner.
