COMBUSTION DEVICE

PROBLEM TO BE SOLVED: To provide a combustion device capable of maintaining stable combustion without being affected by outdoor weather, the presence or absence of wind, and wind directions by improving a combustion device for indoor installation. SOLUTION: A fuel supply amount adjusting valve 60 supplies fuel gas to a burner 17, and the fuel supply amount adjusting valve 60 comprises an air chamber 61 for correcting the movement of a valve element 65 by the pressure of the outside air. A tube 75 (ventilation passage) is provided between the air chamber 61 and an outside air introducing air flow passage. When pressure near an air-supply port exposed to the outside is low, a suction amount of a blower 5 decreases. When the pressure near the air-supply port is low, a clearance between the valve element 65 and a valve seat 63 becomes small to limit a fuel supply amount. Thus, incomplete combustion does not occur. COPYRIGHT: (C)2010,JPO&INPIT
