Definitions

  • This invention relates to burner devices, and has particular, although not exclusive relevance to burner devices for use in vehicles, such as lorries.
  • a burner device in a vehicle, for example as a cab heater, it is convenient for the burner to be fuelled by fuel from the main fuel tank for the vehicle.
  • This requries, however, the use of a flow modulator to control the flow of pressurised fuel from the tank to the burner device.
  • the flow modulator has taken the form of a pump, having a variable pumping rate.
  • a burner device comprising: a fuel conduit having an inlet into which fuel may be admitted, and an outlet by which fuel may exit, an electromagnetic valve for regulating the flow of fuel from the inlet to the outlet, means for igniting the fuel exiting from the outlet, and means for controlling the electromagnetic valve in dependence on the required heating effect of the device.
  • the device suitably incorporates a means for introducing combustion gas into the flow of fuel exiting from the outlet.
  • the combustion gas preferably is arranged also to provide cooling of at least part of the conduit.
  • the device may incorporate a nozzle means communicating with the outlet, the means for introducing combustion gas being arranged to mix pressurised combustion gas with fuel in the nozzle means such that the nozzle means is effective to emit atomized fuel.
  • the first embodiment to be described includes a fuel injector, indicated generally as 1, mounted in a combustion can 3.
  • the combustion can 3 is also provided with a combustion air inlet 5 and an ignitor 7, the ignitor being of conventional design, for example a hot wire glow plug.
  • the fuel injector 1 includes a fuel inlet 9 in which is fitted a filter 11, and a fuel outlet 13, the inlet and outlet being connected by a longitudinal passage 15 formed within a housing 17.
  • the passage of fuel through the fuel injector 1 is controlled by an electromagnetically controlled valve comprising an electromagnet including a solenoid coil 19 supported on coil former 21.
  • the coil former 21 is located inside an annular cavity 23 defined by concentric parts 25 and 27 of the housing 17.
  • Both parts 25 and 27 are made of a magnetizable material, thus providing a magnetic circuit round the solenoid coil 19.
  • the valve further includes a valve plate 29, also made of magnetizable material, which is urged by a coil spring 31 into contact with a valve seat in the form of a disc 33 in which is formed an aperture 35.
  • the valve plate 29, when in the position shown in Figure 1, thus blocks the aperture 35 in the disc 33, thereby preventing the flow of fuel from the fuel inlet 9 through the passage 15 to the fuel outlet 13.
  • valve plate 29 Upon energization of the solenoid coil 19, the valve plate 29 is magnetically attacted towards the adjacent end face of part 23 thus unblocking the aperture 35 in disc 33. Fuel is then able to pass around the valve plate 29 and through the aperture 35 to the fuel outlet 13. Upon de-energization of the solenoid coil 19 the valve plate 29 is returned by the action of the spring 31 into contact with the disc 33 thereby blocking the flow of fuel through the aperture 35.
  • the fuel inlet 9 is connected to the fuel tank of a vehicle (not shown)from which fuel is supplied to the inlet 9 under pressure.
  • fuel which may be liquid or gaseous, passes through the injector 1 into the chamber 3 where it is ignited by the ignitor 7.
  • Auxiliary combustion air pressurised to typically 5 to 10 psi, is admitted via the inlet 5 into the chamber 3 to aid air/fuel miring and also to provide cooling of the injector during and after operation of the burner device.
  • a temperature sensing device shown schematically as 36, whose output is an electrical signal corresponding to the sensed temperature. Signals from the temperature sensing device 36 are used to control the electromagnetic valve so as to regulate the time intervals during which the solenoid coil 19 is energized and fuel can pass from the inlet to the outlet of the injector 1. Means 36a are provided such that the control signals are pulsed, the mark to space ratio, the width of the signals, or the frequency of the signals being variable so as to control the temperature of the cab of the truck.
  • the device as thus described also finds application as a burner for periodically burning off carbon formed on the traps incorporated in the exhaust of a diesel vehicle to trap the carbon particulates emitted due to the combustion of diesel fuel during normal use of the diesel vehicle.
  • the operation of the device will however be arranged to be initiated by, for example, a timing mean, shown schematically in Figure 1 as 38, so as to cause energization of the solenoid coil 19 and thus operation of the burner at appropriate time intervals depending on the accumulation of particulates in the trap.
  • the burner device may also find application in an engine block heater.
  • the combustion air inlet 5 formed in the combustion can 3 in the first embodiment is, in this embodiment, replaced by an adaptor 37 fitted to the housing 17 of the fuel injector 1 via an O-ring seal 39.
  • An air inlet 41 is provided in the adaptor 37, this communicating with an outlet nozzle 43 into which fuel passing from the outlet 13 of the injector 1 passes.
  • a source (not shown) of pressurised combustion gas is connected to the inlet 41, the outlet nozzle thus being effective to supply an atomized spray of fuel.
  • a burner device in accordance with the invention finds particular application in a vehicle so as to use the fuel from the fueltank vehicle
  • a burner system in accordance with the invention is also applicable wherever it is necessary to modulate the fuel flow to the device, for example in an industrial or home heating furnace.
