Abstract: A combustion apparatus includes a combustion chamber having a bottom portion, and a blower for supplying air. An air blowing section is provided at a lower portion of the combustion chamber and blows out the air supplied from the blower toward the bottom portion. As a result, air is moved toward the bottom portion in the center portion of the lower portion of the combustion chamber in a radius direction and combustion gas rises upwardly along a wall of the combustion chamber. Therefore, a maximum combustion temperature portion is confined in the vicinity of the bottom portion by a forced air flow. Also, the combustion temperature in the lower portion of the combustion apparatus is high and that in the upper portion thereof is low. That is, the combustion temperature distribution is inverted, compared to that in the conventional combustion apparatus.
