Abstract

PURPOSE:To prevent a pulsating combustion from occurring by providing primary air quantity setting means for affording differences between burners in primary air quantities to be supplied to a plurality of burners. CONSTITUTION:Respective through holes 71 of a burner damper 70 have large- diameter openings at both end parts, and small-diameter openings alternately toward the central part, where a large number of large-diameter openings are again collected. Air and a fuel gas are mixed, and are ejected through burner ports 42 of a burner head 43 via an inlet port 41 of each burner and an inlet passage 44 thereof. The equal quantity of the fuel gas is supplied to any of burners 40, while primary air in quantities different depending on the diameter of each through hole 71 of the burner damper 70 is supplied thereto. Since the air-fuel ratios in respective burners are different from each other at the burner heads 43, the flame propagation speeds at respective burners are different from each other. Accordingly, the numbers of pulsations and phases in respective burners are different from each other so that the burner as a whole acts to cancel its pulsation.
