Definitions

  • a vaporizing burner includes a combustion chamber having inserted therein a vaporizing body To this body, the liquid fuel is applied to be vaporized. There air is also means forsupplying a combustion air flow to the burner.
  • This flow sweeps along the vaporizing surface of said body, which is made of a porous material having good heat conducting properties and is formed substantially as a cylinder. On the cylindrical outer surface of the body, there are formed spiral channels to force the air flow to move rotationally around the vaporizing body, thereby improving the air-fuel mixture.
  • This invention relates to a vaporizing burner including a combustion chamber having insfiediiiim a cylindrical vaporizing body comprising a porous material with good heat conducting properties.
  • the burner also comprising means for applying a liquid fuel onto said vaporizing body and means for supplying to the burner a combustion air flow, which during rotation sweeps along the cylindrical surface of the vaporizing body.
  • the present invention presents a solution of the problem described above.
  • the turbulator itself of a sintered material having a great capillary action and good heat conducting properties, the vaporizing zone will be placed symmetrically and near the inlet part of the turbulator. Due to the axial extent and the spiral channels of the turbulator, the largest possible mixture length is obtained.
  • a flame holding is provided against the turbulator so that the turbulator receives enough heat from the flame.
  • a steel plate housing 1 encloses a combustion chamber 2.
  • chamber 2 In its left end, chamber 2 is provided with a flame holder 3.
  • a vaporizing body 4 comprising a porous characteristic, for instance, it may be a sintered material with good heat conducting properties, eg pelleted sinter bronze. A sintered, stainless steel material may also be used.
  • the vaporizing body 4 is formed as a turbulator with outer spiral channels.
  • a chamber 5 In the center part of the vaporizing body 4, there is provided a chamber 5, in which there is inserted a glow coil ignition member 6.
  • the chamber 5 is through radial bores 7 connected to the outer part of the vaporizing body and is through an axial channel 8 in connec tion with the left end of the combustion chamber 2.
  • a supply tube 9 for the combustion air To the right end of the housing 1 is connected a supply tube 9 for the combustion air, this tube 9 surrounding another supply tube 10 for the liquid fuel.
  • the supply tube 10 ends in the chamber 5, in which the fuel flows out onto the chamber wall and through the capillaries of the body 4 is spread throughout the entire body.
  • the glow coil ignition member 6 is used to initiate the ignition process in order to heat,vapro ize and ignite the fuel. Due to the turbulator shape of the vaporizing body 4 the flame is developed to the left of the body 4, and the heat is conducted upstream along the body for causing vaporization of the fuel near the inlet end of the body.
  • a vaporizing burner including a combustion chamber and inserted therein a vaporizing body, said burner also comprising means for applying a liquid fuel onto said vaporizing body and means for supplying to said vaporizing body a combustion air flow whereby said fuel and air mix in said vaporizing body, said vaporizing burner comprising a porous material having good heat conducting properties and being substantially cylindrical shaped, with spiral channels on its outer surface for forcing the mixture of fuel and combustion air flow to move rotationally along said surface and through said combustion chamber.
  • said ignition means is a glow-coil inside a chamber co-axial with and inside said vaporizing body, said body having porous walls, said liquid fuel being introduced into said chamber from which it spreads throughout the body via the capillaries formed by said porous walls.
