Definitions

  • the present invention is related to a burner used in domestic cooking devices and which provides multiple gas burning.
  • a single burning system is used in the burning systems of the ovens and stoves used today.

  • Kw limited power
  • burners comprising two or three burning systems and thus having higher power values are also has started to be used extensively.
  • These burners which are called multiple burning systems, house the small burner and the big burner.
  • this burning system there exist one or two inner circle burning and one or two outer circle burning.
  • a homogenous distribution of the flame is obtained as the burner burns in the form of three or four circles.
  • an adequate amount of secondary air feeding needs to be provided in order to prevent the flame of the inner circles from being extinguished.
  • Kw desired power
  • output values may be obtained.
  • the burning generally occurs like this: One or more primary air intake is provided to the system.
  • This primary air is transported to the combustion rooms via perpendicular venturi effect after being mixed with gas in a mixing room.
  • Burning of the inner and outer circles is provided by igniting the air-gas mixture reaching to the combustion ports with an ignition tool.
  • the sparkplug and thermocouple are generally located close to outer circle ports where the first burning is realized.
  • the outer circle burns first and the flame jumps to the inner circles from the outer circles by heating. Again, the burning inflammation is provided by thermocouple with respect to the outer circle ports.
  • the jumping of the flame from the outer circles to the inner circles especially at a low heat, may be troublesome and slow.
  • the inner circle ports does not burn and the unburned waste gas is released to the environment.
  • the desired burning at the inner and outer circles may only be realized with the increase in the dimension of the flame when a saucepan with a big diameter is placed on the burner.
  • designs, in which the inner and outer circle ports continuously burns are needed to be produced.
  • the thermocouple is located only at the outer circle, due to insufficient O 2 transfer, the inner ports will extinguish although the outer ports will keep on burning. In here, as a result of the extinguishment of any one of the inner or outer circles, the security systems have to be shut down after a while.
  • the present invention is a novel multiple gas burner designed to offer solution for all of the problems mentioned above.

  • a part of the primary and secondary air (1.9) sucked from these channels (1.2.9) passes from at least four vertical venturi (1.2.4) by being mixed with the gas passing from the nozzles (1.1) as the primary air while the other part provides air feeding to at least two little flame crowns (1.3) via big flame crown (1.2) space (1.2.7), as secondary air.
  • a primary air-gas mixture (1.11) is obtained and also the extinguishment during burning is prevented by feeding the secondary air (1.12) in the environment to at least two little flame crowns (1.3).
  • the air entering into the burner (1) through these ducts (1.2.9) serves as both primary air and secondary air.
  • these ducts (1.2.6) in order to prevent extinguishment in at least two little flame crowns (1.3), there exist at least two upper ducts (1.2.6) in the big flame crown (1.2).
  • the purpose of these ducts (1.2.6) is to provide secondary air (1.12) feeding by connecting at least two little flame crowns (1.3) to the outer environment.
  • the small flame crowns (1.3) are connected to the big flame crown (1.2), making the big flame crown (1.2) and at least the two little flame crowns (1.3) a single piece.
  • venturis Two of these venturis (1.2.4) carry primary air-gas mixture (1.11) to the big flame crown (1.2) and the other two venturis carry primary air-gas mixture to the little flame crowns (1.3).
