PURPOSE:To obtain the titled pulse burner capable of preventing a continuous combustion and an incomplete combustion and constantly securing excellent combustibility by discriminating between a pulse combustion and a continuous combustion by the output of a pressure sensor and detecting the incomplete combustion by the output of a flame light sensor. CONSTITUTION:In a combustion chamber 4, air supplied from an air pipe 1 is mixed with a fuel supplied from a gas pipe 5. The gaseous mixture thus obtained is exploded by sparks of an ignition plug 9, and the pulse combustion is started. Upon this occasion, if the pressure sensor 11 provided in the combustion chamber 4 decides that the mode of combustion is a continuous combustion, a control part 20 closes an electromagnetic changeover valve 6, and stops the operation of the burner. Further, even if a normal pulse combustion is carried out, when an incomplete combustion is continued for more than a predetermined period of time after a photo conductive element 12 detects the incomplete combustion, and opens a damper 2 to perform the control to suppress the incomplete combustion by the increase in the suction quantity, the operation of the burner is stopped. |
