Definitions

  • the present invention relates to a hood for collecting and conveying fumes originated from boilers or the like.
  • the present invention relates to a hood for collecting and conveying fumes originated from boilers or the like, comprising a safety device for automatically blocking the operation of the boiler in the case where irregularities in the discharging way of the fumes were present.
  • Such a hood may be mainly applied in the field of the thermomechanical industry.
  • the present invention aims to allow a correct operation of boilers and, more particularly, it is a purpose of the present invention to allow the fumes generated during the combustion process of boilers to be properly fed to the exhaust pipes which convey said fumes outside.
  • the hood according to the present invention it is possible to totally eliminate the risk of an accidental leakage of the exhaust fumes inside of the utilization room caused, by way of example, by the obstruction of the exhaust pipe or by other discharging anomalies.
  • the hood according to the present invention comprises a simple, nevertheless effective device for intercepting the fumes within emergency paths and for automatically blocking the boiler operation until the function of the exhaust pipe is restored again.
  • reference sign 10 generally indicates a hood or fumes collector according to the present invention.
  • Said hood is suitable for intercepting the fumes originated, for instance, by the burner of a boiler or by other smaller combustion processes.
  • Said hood 10 comprises a first chamber 11 delimited by planar or arcuated walls which convey the fumes towards a second chamber 12 and from the latter, by means of generally planar walls 14, towards an aspiration duct 13.
  • Said generally planar walls 14 of said second chamber 12 constitute, together with the generally arcuated walls 15 delimiting said first chamber 11 from said second chamber 12, a pair of secondary ducts 16, inside of at least one of which is placed a sensor 17 applied on a fixed board 18.
  • Said sensor 17 which is sensitive to the presence of heat and which may be suitable set to a predetermined temperature, is directly connected to the solenoid valve controlling the delivery of gas and, consequently, the burner operation.
  • the fumes coming from the chamber 11 are conveyed to the chamber 12 and from the latter they are canalized towards the aspiration duct 13 which discharges the fumes outside in the atmosphere.
