PURPOSE:To perform a reliable control of a fluctuation in a burning condition and to perform an accurate adjustment of oxygen concentration in each burner, by a method wherein a perforation for sampling is formed in each burner. CONSTITUTION:If burning air and fuel are fed to a burner body 2 to perform an ignition, a part of air for fuel flows to an ejector 7, exhaust gas in the proximity of a burner tile 1 is sucked through a perforation 8, and an opertion control signal generating device 12 actuates by means of a detecting signal from an O2 sensor 10 and a thermocouple 11. The output from the generating device 12 adjusts the degree of opening of a discharge regulating valve 6 to feed a most suitable amount of air for combustion, and this causes a burner to burn at a low O2 concentration. |
