Definitions

  • the present invention relates to a burner supply system operating on a fuel-water emulsion.
  • Patent FR 2 064 615 is also known, according to which the return of the burner pump opens into a mixer compartment into which the water supply and that of fuel oil also open. Another emulsifier compartment in which the emulsion is prepared is located below the previous compartment.
  • a high pressure pump draws the mixture from the mixer compartment and injects it into the emulsifier compartment. Once the emulsion is made, it is sucked by the burner pump, this through an outlet made in this emulsifier.
  • an emulsion at rest, tends to form two layers, a light upper layer and a relatively heavy lower layer.
  • the burner supply after a shutdown period, is made by the relatively heavy layer rich in water.
  • the device consists of a block of machined metal to create the two compartments and the different accesses (holes, tapping, ...)
  • the device includes a high pressure pump to transfer the liquid from the first to the second compartment.
  • the present invention provides a much simpler and more reliable power system.
  • the problem of ignition, following a shutdown period is eliminated.
  • the supply system of the burners operating with fuel-water emulsion is of the type of those comprising a water inlet, a fuel inlet, an emulsion conduit transporting the emulsion from a mixing means and emulsification to the burner pump, said pump having its return connected to said means for mixing and emulsification.
  • the mixing and emulsifying means consists of a chamber (1).
  • This chamber preferably has a cylindrical shape, but it can have any other shape, this is only dependent on the manufacturing requirements.
  • the water pipe can be directly connected to the pressurized water distribution pipe (not shown), it is controlled by a pressure regulator (4) and a controlled shut-off valve (5).
  • the pressure regulator (4) and the shut-off valve (5) are shown separately in the drawing for reasons of clarity, but in reality these two organs can be grouped together in a single means which fulfills, at the same time, - these two functions.
  • the penetration of this conduit (2) into the chamber (1) is not a functional criterion.
  • the fuel pipe (3) has its other end immersed in a fuel tank (6). At this end a strainer can be mounted. The penetration of the conduit (3) into the chamber (1) is not a functional criterion.
  • a conduit (7) runs from the mixing chamber to the burner pump (8).
  • the penetration of the end of this conduit (7) into the chamber (1) must not reach a level close to the bottom of said chamber.
  • At the outlet of the burner pump (8) there are two conduits: one (9) leads to the burner nozzle and the other (10) again leads to the chamber (1).
  • the latter is called the return duct.
  • the pipe (9) which leads to the burner nozzle is controlled by a flow regulator (11) and a controlled shut-off valve (12).
  • the flow regulator presented on the drawing is a fixed flow regulator, but this one, obviously, can be with variable flow.
  • the burner pump (8) is shown in the drawing with a single outlet, for the sake of clarity. Indeed the pumps used, at present in the burners have two outputs, one is with controlled flow and the other is a return pipe. In reality the flow regulator (11) can be part of an assembly comprising the pump (8).
  • a safety conduit is connected on the chamber (1).
  • This conduit (13) is controlled by a safety valve (14) and leads to the fuel tank (6).
  • this controlled conduit has no role in the functioning of the system, but it is connected to the chamber (1) as a precaution.
  • the safety valve 14 is adjusted to a pressure slightly higher than that prevailing in the chamber (1). Once the threshold of this valve adjustment pressure is exceeded in the chamber (1), said valve becomes conducting in the direction chamber (1) - tank (6). It should be noted that the pressure usually prevailing in the chamber (1) is close to that of atmospheric pressure.
  • the two shut-off valves (5) and (12) are closed.
  • Switching on the burner pump (8) causes a vacuum in the chamber (1), the two valves (5) and (12) being closed, there are two possibilities: - if the chamber (1) is empty, that is to say if the ignition is to be made for the first time, the fuel is sucked up to fill the said chamber then forced to turn in a closed circuit, passing through the conduit (7), the pump (8), the conduit (10) and again through the chamber (1).
  • the chamber (1) is filled with emulsified water, or not, in the fuel, following a previous ignition, no introduction of the fuel into the chamber (1) is possible.
  • the liquid filling the chamber (1) is forced to follow the circuit described above, this lasts until the shut-off valves (5) and (12) are open. Meanwhile the liquid in the said chamber goes into emulsion state. It is, of course, possible to vary the duration of time between the starting of the pump (8) and the opening of the two taps (5) and (12).
  • the control means which manages the delay in the opening of these two shut-off valves can be of all known types, for example electronic, pneumatic or others. This means can also be integrated into the same assembly comprising the pump (8) itself.
  • the flow regulator (11) must be adjusted according to the need for emulsion to be burned, as well as the pressure regulator (4).
  • the flow rate per hour of the burner pump (8) has, in absolute value, at least 150 times the volume of the chamber (1).
  • this flow rate per hour of the pump (8) equal 15 times the hourly consumption of the burner, in other words it is desirable that the chamber (1) has a volume equal, in absolute value, at least to 0 , 01 of the hourly consumption of the burner.
  • the conduits (2), (3), (7), (10) and (3) are, according to one embodiment, connected to the chamber (1) along a straight line.
  • the fuel to be used according to the detailed description above is a light fuel. It is understood that a heavy fuel can also be used, by employing equipment which is well known technically and which plays on the viscosity of this fuel, such as for example heating means.
