| description | The present invention, makes it possible to specifically set an efficient position at which to measure gas concentration, effectively minimize the remainder of unburned fuel by a specific control method based on information representing the measured gas concentration, and improve the boiler efficiency. The present invention is provided with a burner (2), an air supply port (3), a secondary-air damper (42), a measurement unit (5) for measuring gas concentration in a furnace outlet (110), and a control device (90). The air-supply port (3) is divided into two or more groups (31-34), a measurementregion (50) is divided in advance into a plurality of divided regions (51-54) correlated with each divided group (31-34). The control device (90) outputs flow rate control command values for secondary air for the air-supply ports in the respective groups (31-34) corresponding to each of the divided regions (51-54), the flow rate control command values being outputted on the basis of the deviationbetween the average value |
