摘要： In accordance with the flow distribution of combustion gas including an unburned portion, an after-air port (AAP) arranged downstream of the two-stage combustion burner can effectively reduce the unburned portion by dividing as appropriate so as to avoid interaction, and by mixing together, two types of after-air having functions of linearity and spreading. As the configuration of this AAP (7), a primary nozzle (5) for supplying primary after-air (1) and having a vertical height greater than the horizontal width is provided in the center in the opening (17) of the AAP (7), a secondary nozzle (14) for supplying secondary after-air (11) is provided in the opening (17) outside of the primary nozzle (5), and one or more secondary after-air guide vanes (15) having a fixed or variable tilt angle relative to the after-air port center axis (C o ) are provided at the outlet of the said secondary nozzle (14) to deflect and supply the secondary after-air (11) horizontally to the left or right.
