Abstract
PURPOSE:To prevent poisoning caused by carbon monoxide, by a method wherein the fire on a burner is extingushed only when the oxygen concentration is decreased, by providing air holes to the wall of a duct, in the burner disposed with a combustion sensor tube to generate electromotive force by the difference between the oxygen concentrations of the inside and the outside of a tube is provided. CONSTITUTION:When the oxygen concentration in the room is decreased, the flame entering into a duct 10 cannot perform complete combustion by the oxygen contained in the air flowing in from the primary air port 12 alone, but by the air flowing in from the secondary air port 16, while the flame is also formed on the secondary flame port 15. As a result, the upper part of a combustion sensor tube 14 is heated by said flame, the convection current is caused in the sensor tube 14, and the exhaust gas in a duct 10 is discharged by the suction not only from pin holes 19, but also passing through a circulating tube 20. Accordingly, the difference of oxygen concentrations between the inside and the outside of a combustion sensor tube 14 becomes small, the electromotive force of a sensor tube 14 becomes smaller than the predetermined value, and a gas feeding valve 3 cannot be kept in the opened state, so that the feeding of gas of a main burner 1 and a pilot flame burner 4 is stopped.
