さくしなければならなかつた。 As shown in Fig. 1, an outer cylinder D surrounds a combustion cylinder B with a burner group A disposed below with a gap C, and a blower E is provided above to cause combustion in the burner group A through the gap C. A gas combustion apparatus in which a pressure equalizing plate F is provided in the gap C in which air is forcibly supplied is known from Utility Model Application No. 131445/1983. According to this, combustion air is forcibly supplied to the burner group A by the blower E, making it possible to perform high-input combustion, and the pressure equalizing plate F supplies even combustion air to each burner. . However, since the pressure equalizing plate F is provided in the gap C serving as the air passage, the amount of air blown by the air blower E is reduced, and the burner input must be reduced accordingly.

A detailed explanation will be given below with reference to the drawings. Reference numeral 1 denotes a forced air gas combustor of the present invention, which is an example of a gas water heater, and a number of burners 3 are arranged below a combustion tube 2. Reference numeral 4 designates nozzles of the large number of burners 3, which are provided in a manifold 5 and form a nozzle row. Reference numeral 6 denotes an outer cylinder which surrounds the combustion cylinder 2 with a gap 7 in between.

When the blower 8 is rotated, combustion air is supplied from above through the gap 7 between the combustion cylinder 2 and the outer cylinder 6.
In this case, in the gap 7, the amount of air supplied is likely to be large in the center of the nozzle row consisting of the nozzles 4 of a large number of burners 3, and small on both sides, but in the gap in front of the air supply port 21. 7 is provided with a flow divider plate 9, so part of the large amount of air in the center is supplied to the center of the nozzle row by the ventilation part 93, but the rest is distributed to both sides of the nozzle row by the inclined part 92. Approximately uniform air is supplied over the entire length of the nozzle row in the longitudinal direction, resulting in good combustion in all burners.

Ventilation section 9 formed
3, the longitudinal direction of which is connected to the air supply port 2.
1, and is provided in the gap 7 in front of the air supply port 21 with the neck portion 91 facing upward, so that air is almost uniformly supplied over the entire length of the nozzle row facing from the air supply port 21. Good combustion of the burner can be obtained. Since the flow dividing plate 9 is not provided upstream of the air supply port 21 in the gap 7, but is provided in the gap 7 in front of the air supply port 21, the combustion air from the blower 8 does not decrease on the way, and the burner input is also reduced. It can provide high input and eliminate the drawbacks of the conventional method.
