Definitions

  • the present invention relates to a combustion apparatus such as a water heater and a heat source device for heating, and more particularly to a combustion apparatus for heating a heating medium supplied into a heat exchanger, by exhaust gas generated in a burner.
  • the heat exchanger and a burner chamber housing the burner should preferably be configured as small as possible.
  • JP H5-96739 Y discloses that a partition wall having a substantial L shape or U shape is provided on the inner side of a burner chamber side wall, to form a semi-closed space as a pressure absorption chamber on the side of a burner arrangement section. This aims to suppress pressure fluctuation around a burner port.
  • multiple burners 61 are arranged side by side in a substantially central position in the horizontal direction in a burner chamber 71.
  • a partition wall 83 having multiple suction holes 831 is erected to extend between the right and left burner chamber side walls 712, in front of a burner arrangement section S1 in the burner chamber 71.
  • a gap S5 connected to a front space S6 in front of the partition wall 83, is provided between a lower edge portion of the partition wall 83 and a burner chamber bottom wall 711.
  • JP H10 115407 A describes a combustion device provided with an enriched gas concentration burner, a weak gas concentration burner, a fan provided on the bottom of a casing, opening sections which are smaller than a weak gas concentration inlet and a weak gas concentration damper which minimizes the opening areas of the opening sections distant from the aforesaid fan. Due to this construction, the air concentrated in the weak gas concentration inlet distant from the fan is compulsorily controlled so that the same amount of air may flow into each weak gas inlet and the same amount diluted mixed gas may flow out from each weak gas concentration burner. This construction improves the combustion by forming weak gas concentration flames.
  • US 2016/377282 A1 describes a combustion apparatus which has a plurality of longitudinally elongated gas burners, each having a burner port on an upper end thereof.
  • a damper is disposed to cover gas inlet ports on an upstream end of an air-fuel mixing tube portion of each of the gas burners.
  • the damper has formed therein ventilation holes for limiting primary air. The ventilation holes overlap, and are smaller than, the gas inlet ports.
  • the damper has ventilation holes having obstacles against which the fuel gas to be ejected from the gas nozzles strike, and further ventilation holes without obstacles. Poor combustion such as flame lifting is restricted and combustion noises are reduced.
  • the present invention has been made in view of the above problem, and aims to provide a combustion apparatus such as a water heater and a heat source device for heating that can improve combustion stability while reducing noise generated during combustion operation.
  • the present invention is a combustion apparatus according to claim 1.
  • the flow controller provided at the front of the side of the suction hole area of the partition wall can restrict air introduced into the burner chamber from forming a turbulent flow at the front of the side of the suction hole area, that is, in the no suction hole area, and flowing to the suction hole area side. Accordingly, primary air is uniformly introduced into the suction holes from the front space. Hence, the combustion state is less likely to vary among the burners.
  • a damper plate is provided on a front face of the partition wall along a peripheral edge portion of the suction holes, and the flow control plate is formed integrally with a side end portion of the damper plate.
  • the flow control plate is formed integrally with the damper plate provided along the peripheral edge portion of the suction holes, the flow controller is less likely to be misaligned with respect to the suction hole area. Hence, it is possible to more appropriately restrict the flow of air from the no suction hole area to the suction hole area side. Moreover, since the damper plate and the flow control portion are integrally formed, there is no need to dispose the flow controller on the front face of the partition wall separately from the other members. Hence, it is also possible to reduce the number of parts of the whole apparatus and the number of assembly steps.

    une plaque de contrôle d'écoulement (37) courbée vers l'avant à partir de portions d'extrémité latérales droite et gauche d'une plaque d'amortissement (17) disposée devant la paroi de séparation (33) et formée d'un seul tenant avec la plaque de contrôle d'écoulement (37), et s'étendant essentiellement verticalement depuis une portion de bord supérieur jusqu'à une portion de bord inférieur de la paroi de séparation (33), pour empêcher l'air introduit dans la chambre de brûleurs (21) de s'écouler depuis la zone sans trou d'aspiration (A2) jusqu'à la zone de trou d'aspiration (A1), ou
    une protubérance (38) qui fait saillie jusqu'à une position essentiellement de niveau avec la demi-face supérieure (34) de la paroi avant (213) de chambre de brûleurs sur le côté extérieur de la surface avant de la paroi de séparation (33) pour empêcher l'air introduit dans la chambre de brûleurs (21) de s'écouler depuis la zone sans trou d'aspiration (A2) jusqu'à la zone de trou d'aspiration (A1).
