Abstract
PURPOSE: To obtain satisfactory state of combustion of pulverized coal in a rotary kiln, by eliminating or extremely reducing the volume of primary air conveying pulverized coal and allowing separately supplied primary air to be jetted from a burner at high speed.
CONSTITUTION: Two pulverized coal conveying pipe 12, which carries pulverized coal 11 to a burner main 7 from the rear section, are provided on the center core section of the burner main body 7. A primary air supply pipe 14, which is used also for cooling and provided on the tip with a cooling porous plate 13 for cooling a burner 9, is provided around the pulverized coal conveying pipe 12. A primary air supply pipe 16, which is equipped on the tip with a guide vane 15 for sending air from the rear section of the burner main body 7 and causing a swirling, current is provided around the primary air conveying pipe 14, and then, a primary air conveying pipe 17, which makes air flow straight from the rear section of the burner main body 7, is also provided around the pipe 16. Of the burner main body 7, the section to be inserted into a kiln is covered by a refractory 8. Further, total volume of primary air is to be 5W15% of theoretical combustion air volume.
