Abstract
A combustion apparatus for NO reduction and CO reduction capable of achieving stable NO reduction with simple means. The combustion apparatus for fulfilling NO reduction by controlling the temperature of combustion gas derived from a burner includes NO reduction means having an excess air ratio versus NO characteristic that generated NO value decreases with increasing excess air ratio of the burner , and an excess air ratio versus CO characteristic that exhaust CO value increases with increasing excess air ratio, and excess-air-ratio control means for controlling the excess air ratio of the burner to a specified excess air ratio, wherein the excess-air-ratio control means includes outside-air temperature detection means and controls the excess air ratio to the specified excess air ratio based on a detection signal derived from the outside-air temperature detection means
