Definitions

  • the invention regards an oilburner with a heating device to heat the oil and with an oilpump to lead the oil through the heating device.
  • An oilburner of the type mentioned in the beginning is applied for burning, among other things, waste-oil and heavy oil with a high viscosity. To lower the viscosity of these oils and to make these oils appropriate for burning, it is necessary to pre-heat the oil, which takes place in the heating device.
  • the heating device of this conventional oilburner has a high surface capacity.
  • a disadvantage of this conventional oilburner is that because of the high surface capacity of the heating device the oil can start cracking locally, with the result that carbon particles can be formed and can built up upon the heating device. When carbon parts of this carbon residue break loose, they can cause obstructions, especially in the burnerhead of the oilburner, resulting in an irregular burning or even stop the burning.
  • the present invention intents to provide an oilburner of the in the beginning mentioneype, in which this inconvenience is solved in a simple, but efficient way.
  • the oilburner of the invented type has the characteristic that the heating device includes a first chamber provided with a heating element and an adjacent second chamber, separated from the first by a wall, whereby both chambers are thus connected by oilconduits that the oil is led first through the second chamber, then through the oilpump and finally through the first chamber.
  • the heat,_generated in the first chamber by the heating element is partially transferred to the second chamber via the wall between the first and the second chamber.
  • the oil within the second chamber will already be heated, so that the final heating of the oil in the first chamber requires less heat supply.
  • the time that the oil is in the heating device is considerably longer, so that the surface capacity of the heating element can be considerably lower.
  • the chance of cracking of the oil and the deposition of carbon particles is considerably reduced.
  • the outlet of the first chamber is connected by a circulation conduit to the inlet of the second chamber and in said conduit is installed a precision flowregulator.
  • both chambers are made cylindrical whereby the second chamber surrounds concentrically the first chamber for almost its complete length.
  • the chambers are placed vertically with their inlets on the lower end and their outlets on the upper end, the hottest oil with the lowest viscosity -the oil that is most suitable to be led to the burnerhead- will be on top.
  • the first chamber with an automatic air-vent at the top of it, with its connection to this chamber higher than the connection of the outlet to the first chamber.
  • the second chamber can be provided with a manually operated air-vent at the top, with its connection to this chamber higher than the outlet connection to the second chamber.
  • This manually operated airvent can be used when the second chamber has to be filled with oil in the beginning stage of the use of the oilburner, and when the air in the second chamber has to escape. During further use of the oilburner this manually operated air-vent is mainly not used.
  • Fig.1 shows in outline an oilburner of the invented type shortly before the actual burning and fig. 2 shows the oilburner of fig.1 during the burning.
  • the in the figs. only in outline reproduced oilburner has a heating device (1) to heat the oil which is supplied from oilreservoir (2).
  • the oilreservoir (2) sits on a higher level than the heating device (1) so that this difference in height can be used for the oil transportation.
  • the heating device (1) comprises a first chamber (3) in which a heating element (4) can be found.
  • the heating element (4) is connected to a not further specified powersource by means of wire (5).
  • the heating device (1) comprises a second chamber (6) which borders the first chamber (3) and is separated from it by wall (7).
  • both chambers (3)(6) are made cylindrical, whereby the second chamber (6) concentrically surrounds the first chamber (3) for almost its complete height.
  • the second chamber is provided with an inlet (8) at the bottom and an outlet (9) at the top. Moreover the second chamber is provided with a manually operated air-vent (10) at the top.
  • the first chamber (3) is provided with an inlet (11) at the bottom and an outlet (12) at the top. Further is the first chamber (3) provided with an automatic air-vent at the top, with its connection (14) above the outlet (12) of the first chamber (3).
  • the outlet (9) of the second chamber is connected to the inlet (11) of the first chamber by means of a conduit (15).
  • an oilpump (16) is included, which is driven by a motor (17).
  • Motor (17) drives also compressor (18) that forces primary air to the burnerhead (20) via airconduit (19).
  • motor (17) drives the centrifugal fan (21), that forces the so called manifesty air to the burnerhead (20).
  • Outlet (12) of the first chamber is connected to the burnerhead (20) via conduit (22), which conduit (22) comprises a solenoid valve (23). Also connected to outlet (12) of the first chamber is circulation conduit (24), further connected to the inlet (8) of the second chamber, which circulation conduit (24) comprises a flowregulation valve (25).
  • Conduit (26), connecting oilreservoir (2) to inlet (8) of the second chamber, comprises finally a valve (27).
  • heating device (1) When heating device (1) is empty and has to be filled with oil, the manually operated air-vent (10) is opened, while via conduit (26) and valve (27) oil flows from the oilreservoir (2) to the second chamber (6). This flow is caused by the height difference between oilreservoir (2) and the heating device (1).
  • the oil When the second chamber (6) is completely filled, the oil will reach the oilpump (16) via outlet (9) and the conduit (15). The oilpump transports the oil via inlet (11) to the first chamber (3).
  • Fig. 1 shows the oilburner at the moment when it is started.
  • the first chamber (3) and the second chamber (6) are filled with oil and heating element (4) is switched on.
  • the solenoid valve (23) in conduit (22) is closed, so there is no connection between outlet (12) of the first chamber and burnerhead (20).
  • the flowregulating valve (25), on the other hand, is opened, so that outlet (12) of the first chamber is connected to inlet (8) of the second chamber.
  • solenoid valve (23) is opened, while flow regulating valve (25) is at least partially closed. This situation is reproduced in fig.2.
  • the oil flows first through the second chamber (6), next through conduit (15) and oilpump (16), then the first chamber (3) and through conduit (22), to reach finally burnerhead (20).
  • the oil flows first through the second chamber (6), next through conduit (15) and oilpump (16), then the first chamber (3) and through conduit (22), to reach finally burnerhead (20).
  • a small part of the oil will flow via circulation conduit (24), through inlet (8) back to the second chamber (6).
  • the oilburner of the invented type has a burnerhead (20) of the low pressure air atomizing type, whereby both air and oil are atomized under low pressure.
  • the overpressure is in general lower than one Bar. It is easy to reach this low overpressure, only the flow regulating valve (25) has to be put in the right postition.
  • the heating element is placed vertically. Both inlets (8)(11) are situated at the bottomof the respective chambers, while both outlets are situated near the top. This results in that the hot oil will rise to the top while heating, so that the oil with the lowest viscosity, most suitable to be burned, will be carried off via the outlets.
  • the oilburner of the invented type has a number of major advantages.
  • the oil is prevented from cracking locally. Clogging by carbon particles will therefor occur less frequently.
  • the shown configuration guarantees that the oil with the lowest viscosity is always at top, necessary for an optimal atomizing and burning.
  • the version in which the second chamber surrounds the first chamber prevents heat losses caused by radiation, while the air-vents solves the problem of air in the conduits.
  • the invention is not limited to the embodiment as described above, which can be varied within the framework of the invention.
