  • Holes 74 and 76 are provided in the casing 32 and holes 77 in theplate 66 so that air will be circulated through a cooling space 75 between the casing 32 and the part 28 above the pulley 38 and through the annular rotor cooling space 68 defined within the rotor, by reason of centrifugal force exerted on the air during rotation in the annular space 68.

  • the primary zone is the space 18 within the annular wall 14 and the secondary zone is the space 11 between the annular wall 14 and the frustoconical baille 7.
  • fuel is delivered by the disc 78 into the primary zone 18 in which, as explained above, the flow is downwardly, and the lluid consists of a mixture of air, burning products of combustion and unburnt fuel. This mixture then llows through the passage 17 between the inturned flange 16 and the casing 32, radially outwards between the upper impeller blades 70 and into the secondary zone 11 where the mixture of fuel and gases mingle with additional combustion air drawn in through the intake orifice 2 by the lower blades 71 of the rotor.
  • a further part of the total combustion air is delivered into the secondary zone 11 after passing through the tapered passage 1u and the holes 12 in the frusto-conical baflle 7 while the combustion products are finally exhausted through the open upper end of the combustion space 11.
  • the electric motor When the electric motor is started it rotates the casing 32 causing the impeller rotor to rotate and thus create the necessary llow of combustion air into the combustion chamber as a whole and the re-circulation flow within that chamber itself. It also causes fuel to be drawn up the helical passage deiined by the helical member 50 and delivered through the annular space between the upper ends of the fuel pipe 28 and the overflow pipe 40 to the interior of the outlet tube 28.
  • the fuel within the outlet tube 28 tends to rise up the inner wall of the tube so that the surface of the fuel is in the general form of a concave meniscus, having its center at the upper end 41 of the spill pipe 40 so that the level of the meniscus is determined by the level of the upper end 41 of the overllow pipe 40.
  • the outermost and highest part of the meniscus extends to the upper end of the outlet tube 28 where the fuel is tlung radially outwards across the perforated plate or disc- 6 78 and into the primary zone of the combustion chamber by centrifugal force where it is initially ignited by suitable means (not shown).
  • the rate at which the fuel is delivered by centrifugal force from the upper end of the fuel pipe 28 thus depends upon the speed of rotation and upon the vertical position of the upper end 41 of the overflow tube 40 which controls the level of the fuel in the outlet tube 28.
  • the spiral member 50 is thus so designed that its pumping action is sullicient to supply fuel continuously to the outlet tube 28 at least equal to and preferably greater than the maximum rate that fuel is required to llow out of the outlet tube 28 in addition to providing a suilicient ilow of fuel through the transverse bores 51 in the fuel pipe 28 to provide the necessary cooling llow behind the pulley 38 and the outer casing and to lubricate the bearings 26, 27 excess fuel flowing down the overflow tube 40.
  • the overflow tube 40 When maximum heat is required from the combustion chamber the overflow tube 40 will be in its uppermost position as will the outer casing 32 to which the impeller rotor is connected so that there is a maximum llow -of combustion air into and within the combustion chamber to supply the necessary ilow required for the maximum fuel distribution conditions.
  • the outer casing 32 including the impeller rotor 15 moved downwardly away from the combustion chamber so that the upper impeller blades move away from the inturned ilange 16 of the inner wall 14 rendering them less effective and producing a reduced reversed gas llow through the primary zone inside the inner wall 14.
  • the lower impeller blades 71 similarly move out of alignment with the annular space between the annular deflector 13 and the outer shell 1 so that they draw less combustion air into the combustion chamber.
  • the overilow pipe 40 is simultaneously lowered to an even greater extent than the outer pipe 28 so that the fuel ilow is also reduced.
  • the arrangement is such that when the outer casing 32 and its associated rotor are in their lowermost positions the lower impeller blades 71 are clear of the outer shell 1 so that there is no induced flow into the combustion chamber of combustion air, and the upper impeller blades are sulliciently far away from the lower flange 16 of the inner Wall 14 for their effect to be so considerably reduced as to be almost negligible.
  • the llame in the combustion chamber is reduced to a small annular ring on the perforated disc 78 close to the upper end of the fuel pipe 28 where the fuel continues to burn whilst creating very little heat in the combustion chamber.
  • a small llame of the type described above may be allowed to burn for a very great length of time with only a small consumption of fuel and that if heat is required from the combustion chamber it is immediately available merely by operating the member 47 to move the outer casing 32 together with its associated rotor and the spill pipe 40 upwardly to the appropriate position.
