Abstract: PURPOSE:To improve the combustion performance of the titled burner and reduce the combustion sound generated at the time of combustion by effectively supplying secondary combustion air to the titled burner by a natural draft corresponding to the rate of combustion. CONSTITUTION:Since a secondary air inlet path 54 is provided by penetrating through a head chamber 42, a vent path 46, and an evaporating chamber 39, the secondary inlet path 54 is heated by transfer heat or radiation heat from the wall surface and the like of the evaporation chamber, at the time of preheating, and by transfer heat or radiation heat from fire flame and the like, at the time of combustion, whereby secondary combustion air is supplied to a secondary air port 53 through a secondary air inlet path 54 by natural draft due to drafting force in correspondence to the rate of combustion. Accordingly, combustion outside the burner port 40 does not fall into an air deficient condition because the deficient quantity of primary combustion air is replenished by the secondary combustion air due to the above described natural draft. For this reason, combustion can be performed under a condition in which the quantity of primary combustion air is small, the noise amplification due to fire flame can be suppressed to a small value.
