Definitions

  • the invention relates to a forced air burner, comprising more particularly a combustion head mounted on a housing extending next an axial direction, a ventilation turbine mounted around an axis of rotation fixed relative to the housing and a diffuser directing a combustion air flow generated by the ventilation turbine to the combustion head.
  • US Pat. No. 2,986,207 discloses burners of this type. type in which the ventilation turbine and the diffuser extend in a plane of the housing perpendicular to the axis of rotation and perpendicular to the axial direction of the combustion head. This arrangement imposes a right angle bend at diffuser which causes a significant pressure drop of the air flow blown to the inlet of the combustion head.
  • the ventilation turbine and the diffuser extend in a plane of the casing perpendicular to the axis of rotation and parallel to the axial direction of the combustion head.
  • This arrangement allows a good flow of the blown air flow to the combustion head.
  • it does not favor access to the combustion head: it is generally necessary to provide a mechanism, for example with slides or hinges, allowing the casing to be moved to disengage the combustion head during maintenance operations.
  • provision is made to access the head of combustion by a section of the diffuser outside the housing and bent at right angles. This arrangement introduces a pressure drop of the flow of air blown towards the head of combustion and increases the size of the burner between the housing and the head of combustion.
  • document GB 2233439 discloses a burner of this type in which the diffuser is arranged for a reason of compactness in the housing on which the combustion head is mounted and extends in a plane of the housing perpendicular to the axis of rotation of the ventilation turbine by being inclined by ratio to the axial direction of the combustion head of a neighboring angle of inclination 45 degrees.
  • This arrangement allows access to the combustion head without move the casing on which it is mounted.
  • the inclination of the diffuser by compared to the crankcase again leads to increase the pressure drop of the air flow blown by the ventilation turbine.
  • the object of the invention is to modify a burner of the type recalled above to improve the flow of the air flow blown by the ventilation turbine.
  • the subject of the invention is a burner of the type described previously, characterized in that the diffuser extends in the plane of the housing perpendicular to the axis of rotation, in a direction of diffusion making a diffusion angle between 10 and 50 degrees, preferably between 20 and 50 degrees, with a projection of the axial direction of the combustion head into the plane perpendicular to the axis of rotation of the ventilation turbine.
  • the diffuser extends in the plane of the housing perpendicular to the axis of rotation, in a direction of diffusion making a diffusion angle between 10 and 50 degrees, preferably between 20 and 50 degrees, with a projection of the axial direction of the combustion head into the plane perpendicular to the axis of rotation of the ventilation turbine.
  • adjustment or control components electrical system are arranged on a face of the casing parallel to the plane perpendicular to the axis of rotation to be easily accessible and so further increase the ergonomics of the burner.
  • this face of the casing inclined for example between 10 and 50 degrees by horizontal report is very convenient for performing visual checks or disassembly.
  • a forced-air burner comprises a combustion head 1 mounted on a housing 3 extending in one direction axial axis A, for example horizontal, and a ventilation turbine 5 mounted in a casing volute 7 about an axis of rotation 9 fixed relative to the housing.
  • the head of combustion and the volute communicate with each other via a diffuser 11 of the housing, for example formed by a portion of the housing itself arranged in output of the volute, to direct a flow of combustion air generated by the turbine of ventilation to the combustion head.
  • the volute 7 and the diffuser 11 extend in a plane P of the casing perpendicular to the axis of rotation 9 and inclined with respect to the axial direction A of the combustion head 1.
  • the plane P perpendicular to the axis of rotation 9 and the axial direction A preferably form between them an angle of inclination incl between 10 and 50 degrees.
  • the combustion head 1 is supplied with liquid or gaseous fuel by a non-feed circuit represent. In the case of a liquid fuel, this circuit comprises a pump debiting in a liquid fuel atomization system inside the head of combustion 1.
  • the diffuser 11, in the plane P perpendicular to the axis of rotation 9, extends in a diffusion direction D making an angle of diffusion b between 10 and 50 degrees, preferably between 20 and 50 degrees, with the projection of the axial direction A of the combustion head 1 in the plane P.
  • An angle of diffusion greater than 50 degrees increases the loss of charge of the diffuser in comparison with the compactness gain in the axial direction of the combustion head.
  • An angle of diffusion less than 10 degrees increases too much conversely the space in the axial direction of the combustion head in comparison of the reduction of the pressure drop of the diffuser.
  • control components, electrical control or fuel supply are arranged on a face 15 of the casing 3 parallel to the plane P perpendicular to the axis of rotation 9.
  • the burner according to the invention is assembled from a housing by example manufactured in one piece by a foundry process. After having arranged the ventilation turbine in the volute around the axis of rotation, the housing is closed by a cover forming the face opposite to that which is intended to receive the adjusting, electrical control or fuel supply components.
  • the air blown by the ventilation turbine is directed by the diffuser towards the combustion head to be mixed with a fuel.
  • the mixture of fuel and oxidizer is ignited.
  • the good distribution of the mixture in the combustion head and the stability of the pressure and flow from the ventilation allow the burner to create a healthy and stable flame.
  • the burner is mounted on a heat generator. From the quality of the burner will flow that of the generator.
  • the combustion head, the ventilation turbine and the control system of the burner are controlled and maintained regularly.
