Definitions

  • Such heating apparatus generally comprise a fuel reservoir supplying a combustion chamber through the intermediary of a constant-level tank.
  • the constantlevel tank limits the delivery flow-rate of fuel to the combustion chamber which is equipped with a burner which is most frequently a gasification type burner.
  • Heating apparatus of this type gives satisfaction for the most part, but it is sometimes subject to operational defects which affect its heat efficiency and even result in breakdown.
  • An aim of the present invention is a heating apparatus using liquid fuel, which isfree of such disadvantages.
  • the heating apparatusutilizing liquid fuel is of the kind comprising a frame, a combustion chamber fixedly mounted on the frame, a pipe mounted on the frame for supplying the combustion chamber with liquid fuel, a fuel supply unit removably mounted on the said frame and comprising a fuel reservoir and a constant-level tank, and coupling means for detachably interconnecting said unit and said pipe, said coupling means comprising a first complementary connecting portion fixedly mounted relative to and in communication with the constant-level tank and a second complementary connecting portion fixedly mounted on the frame in communication with the pipe, said coupling means being so positioned as automatically to bring .the fuel supply unit into operative connection with the pipe when the said unit is placed in position on the frame.
  • the replacement does not necessitate any special tools and may be carried out very rapidly, with sufficient rapidity to avoid the stopping of the heating apparatus.
  • FIG. I is a view in elevation, with parts broken away, of a heating apparatus according to the invention, in working order;
  • FIG. 2 is a view similar to FIG. 1 during the course of the replacement with a standard supply unit for this heating apparatus;
  • FIG. 3 is a partial view in perspective of this supply unit
  • FIG. 4 is a partial view in cross-section of the heating apparatus according to the invention, taken along the line IVIV of FIG. 2;
  • FIG. 5 is a partial view in elevation showing a detail of FIG. 1 to a larger scale and with parts broken away.
  • a heating apparatus comprising a frame 10 forms a parallelepipedstructure. On this frame 10 is fixed laterally a casing 11 and an access grating 12 is hinged at the upper part of frame 10.
  • a known heating apparatus of this kind comprises, in the frame 10, a liquid fuel reservoir 13, a constant-level tank 15 coupled to the reservoir 13 by a pipe 16, and a combustion chamber 17 supplied with fuel by the constant-level tank 15 through the intermediary of a pipe 18.
  • the reservoir 13 and the constant-level tank 15 are fixed on a support plate 19 and form therewith a supply unit 20 removably mounted on the frame 10.
  • the frame 10 is therefore provided for that purpose with two rigidly fixed slides 21 which extend along the height of the heating apparatus, parallel to the combustion chamber 17, and are held at a distance from the combustion chamber 17 by cross'members 22, of
  • a free ventilation zone 23 is thus formed between these slides 21 and the combustion chamber 17.
  • the slides 21 are connected together by a partition 25 on their side nearest the combustion chamber 17.
  • the support plate 19 of the supply unit 20 also forms a partition and is provided with lateral flanges 26 adapted cooperate with the slides 21.
  • the support plate 19 can thus be fitted into the volume delimited by the slides 21, as indicated in chain-dotted lines in FIG. 4.
  • the plate 19 in combination with the partition 25 which joins the slides together forms a double wall and rests on an abutment 27 carried by the partition 25.
  • an opening 28 is provided which forms a lifting handle.
  • the reservoir 13 is fixed to the support plate 19 by means of brackets 29 which hold it at a distance from the plate 19.
  • the constant-level tank 15 is fixed on the plate 19 by means of a bracket 30 which holds it at a distance from the plate 19, and to which it is fixed by legs 31.
  • the tank 15 is further provided with a coupling sleeve -35 passing through the bottom thereof and which is capable of being supplied with fuel under the control of a valve member 36.
  • the member 36 is operated by a rod 37 coupled to an actuating knob 38 disposed at the top of the reservoir 13.
  • the frame carries a fixed nozzle 40 which is connected to the supply pipe 18 for the combustion chamber 17 and is complementary to the coupling sleeve 35 of the tank 15. This nozzle 40 is arranged vertically below the coupling sleeve 35.
  • This new supply unit is from that time ready to be put into operation by actuation of its control knob 38.
  • the standard supply unit replacement thus effected can be carried out fairly rapidly so that the combustion chamber 17 remains supplied by the volume of fuel contained only in the pipe 18.
  • the present invention is not limited to the form of embodiment described and shown, but includes any alternative form of construction.
  • the separable coupling means provided between the tank 15 and the pipe 18, comprising a sleeve 35 carried by the tank 15 and a fixed nozzle 40 carried by the frame and coupled to the pipe 18, may be replaced by any other appropriate separable coupling means, in particular a nozzle carried by the tank and a fixed complementary sleeve carried by the frame and connected to the pipe 18.
  • the supply unit comprises an individual reservoir which serves as a fuel source.
  • the reservoir may be replaced by a pump coupled to an external fuel reservoir intake. This may be the case in certain installations in which various individual heating apparatus are supplied by a common reservoir.
  • a heating apparatus using liquid fuel comprising a frame, a combustion chamber fixedly mounted on the frame, a pipe mounted on the frame for supplying the combustion chamber with liquid fuel, a fuel supply unit removably mounted on the said frame and comprising a fuel reservoir and a constant-level tank, and coupling means for detachably interconnecting said unit and said pipe, said coupling means comprising a first complementary connecting portion fixedly mounted relative to and in communication with the constant-level tank and a second complementary connecting portion fixedly mounted on the frame in communication with the pipe, said coupling means being so positioned as automatically to bring the fuel supply unit into operative connection with the pipe when the said unit is placed in position on the frame, said first complementary connecting portion of said coupling means comprising a coupling sleeve and the second complementary connecting portion comprising a fixed nozzle, the coupling sleeve being adapted to be fitted directly on the nozzle.
  • a heating apparatus according to claim 1, wherein the nozzle-sleeve combination has a fluidtight seal.
  • a heating apparatus wherein said supply unit further comprises a support plate on which said reservoir and said tank are fixed, said support plate being slidably mounted in slides rigidly fixed on said frame.
  • a heating apparatus wherein the slides are spaced from the combustion chamber so that a ventilation space is formed between said combustion chamber and said supply unit.
  • a heating apparatus wherein the support plate forms a partition having lateral edges cooperating with the slides, and wherein said slides are connected to each other by a partition along their sides remote from the supply unit, so that the combustion chamber is separated from the supply unit by a double wall when the supply unit is in position on the frame.
  • a heating apparatus according to claim 3, wherein said reservoir and said tank are fixed to the support plate of said supply unit by brackets which hold them at a distance from the said plate.
  • a heating apparatus according to claim 1, wherein said supply unit has a lifting handle.
