Abstract
A combustion apparatus has: a combustion housing; a partition plate provided in the combustion housing to partition a space in the combustion housing into a combustion chamber and an air supply chamber; and a plurality of rich-lean burners arranged in a right-left direction of the combustion chamber. A multiplicity of distributed holes are formed in the partition plate through which distributed holes secondary air is supplied from the air supply chamber to the combustion chamber. A flame rod facing to an upper side of a part of the rich-lean burners stops combustion when the flame rod does not detect any flames owing to a flame lift at a time of an oxygen deficiency. A supply quantity of the secondary air to the part of the rich-lean burners to which part the flame rod faces is larger than those to other parts.
