Abstract:
In a combustion apparatus provided with: a combustion box having a connection flange part for connecting a heat exchanger to an upper end of the combustion box; a partition plate disposed inside the combustion box for partitioning space inside the combustion box into a combustion chamber and an air supply chamber which lies under the combustion chamber; and a plurality of laterally arrayed burners which are elongated longitudinally, the internal volume of the combustion box is increased without increasing a height dimension or without enlarging the connection flange part, thereby restraining the occurrence of resonance sounds. A drawn part projecting laterally outward of the combustion box is provided in such a portion of each side-plate part as is above the partition plate, over a predetermined range in the vertical and longitudinal directions. An upper side of the drawn part is preferably positioned below the upper end of the burners, and is preferably parallel with the upper end of the burners.

Claim (Index 1):
A combustion apparatus comprising:\n a combustion box having, on an upper end thereof, a connection flange part for connecting thereto a heat exchanger; a partition plate inside the combustion box in order to partition space therein into a combustion chamber and an air supply chamber which lies under the combustion chamber; a plurality of burners which are laterally arrayed in the combustion chamber, each of the burners being longitudinally elongated with flame holes on an upper end thereof such that air can be supplied from the air supply chamber to the combustion chamber through a multiplicity of distribution holes formed in the partition plate; wherein a drawn part is disposed in a portion, above the partition plate, of a side-plate part on each lateral side of the combustion box, the drawn part being projecting laterally outward of the side-plate part over a predetermined range in the vertical and longitudinal directions.
