Abstract: PURPOSE:To restrict a vibratory combustion by a method wherein a combustion part for performing a high load combustion, a supplying part for forcedly supplying combustion air to be combustion part and means for increasing the natural frequency of the combustion part higher than that of the supplying part are provided. CONSTITUTION:Although a sound suction member 25a is arranged in a discharging pan 25 so as to reduce combustion noise, the discharging pan 25 is bent to vary a shape of a discharging system, due to this arrangement, it is sometimes found that a pressure loss is generated to cause a vibratory combustion. However, when combustion air is passed through a suction passage 66, the air is passed through a cylinder part 63 in which an extremity end 62 is fitted into a fan 45 only by a desired size l1* set in consideration of an amount of air of a centrifugal blower 40 and an opening area S1* of a bellmouth suction port 61. A shielding plate 7 is positioned at such a position as one in the upper part at the bellmouth suction port 61, i.e. the opening area S1* of the suction port is varied. That is, since the natural frequency f1 of a supplying part 3 is made smaller than that of vibration f2 of a combustion part 2, a vibratory combustion may not occur from an ignition time to a normal combustion time.
