摘要： PURPOSE:To eliminate the need for mounting of a sensor in the vicinity of a burner and to eliminate limitation of the installing condition of a boiler, by a method wherein a pressure detecting device, which detects a change in a pressure produced in a combustion chamber occasioned by ignition and failure in ignition of the burner, is mounted to a fuel feed piping. CONSTITUTION:Feed water 4, burner fuel 5, the air 6 for combustion, and pilot fuel 7 are fed from a ground to a boiler 1 installed to the forward end of a cylinder 2, ignition is effected by an ignitor 8 to reduce steam 3, and exhaust gas 9 is exhausted to a ground. A signal from a pressure converter 10, attached to a fuel feed piping 5, is sent through a filter and an amplifier 12 to a frequency analyzer and/or a differentiator 13 where the presence of combustion vibration frequency and/or impulse pressure wave is detected, and a deciding and processing part 14 decides ignition or failure in ignition of a burner to provide a control signal 15. This eliminates the need for mounting of a sensor in the vicinity of a burner, and enables elimination of limitation of a boiler installing condition.
