BURNER AND WATER HEATER COMPRISING SAME

WIPO Patent Application WO/2022/220491

A1

According to the present invention, a burner for a water heater located upstream of a combustion chamber on the basis of a reference direction, which is a flow direction of a combustion gas generated by a combustion reaction, comprises a plate-shaped distribution plate for generating a combustion reaction, wherein: when one direction orthogonal to the reference direction is referred to as a longitudinal direction, and a direction perpendicular to the reference direction and the longitudinal direction is referred to as a width direction, a plurality of through-holes formed through the distribution plate along the reference direction so that a mixture of fuel and air for the combustion reaction pass through, are formed to be spaced apart from each other in the longitudinal direction and the width direction; the distribution plate has a central portion that is a portion located at the center with respect to the width direction, and an outer portion located on both sides of the central portion; and the penetration density that is obtained by dividing the sum of the areas of the through-holes, which are located at the outer portion, by the area of the outer portion, is less than the penetration density that is obtained by dividing the sum of the areas of the through-holes, which are located at the center portion, by the area of the center portion.
