Abstract
A combustion apparatus which includes tertiary air chambers are formed on both sides of a secondary combustion chamber, with tertiary air being supplied to a combustion flame produced within the secondary combustion chamber. The secondary combustion chamber has a flow channel width greater than a width of an opening in a throttle plate provided on the upstream side thereof, thereby achieving universality with respect to enabling use of various fuel and to increase the capacity of the combustion apparatus while reducing the size thereof.
