PROBLEM TO BE SOLVED: To provide a small combustion device capable of restraining CO and NOx from being produced. SOLUTION: The combustion device supplying indoor air taken into a body 1 by a blower 2, as secondary air to flames formed in a burner 3, is provided with secondary air supply holes 12 for supplying secondary air to the flames, in the whole periphery of a combustion chamber 5 to supply secondary air to the flames from all directions. The flames are thereby drawn to the center by the secondary air supplied from the whole periphery without deviating in a specific direction, so that flames are prevented from contacting a combustion chamber 5. CO and NOx can thereby be restrained from being produced, and the combustion chamber 5 can be formed small in comparison with a conventional one. COPYRIGHT: (C)2007,JPO&INPIT |
