Abstract
A burner and port combination for the combustion of a pulverized coal fuel plus air mixture comprises a throat and a burner nozzle positioned at a central area of the throat. The burner nozzle has an inlet for receiving the pulverized coal fuel plus air mixture and an outlet for discharging the pulverized coal fuel plus air mixture. A secondary air tube is positioned laterally adjacent the burner nozzle at each lateral side of the nozzle in the throat for providing a first portion of a secondary air to the throat. A plurality of vanes are positioned at an upper portion of the throat above the burner nozzle and the tubes and at a lower portion of the throat below the burner nozzle tubes for deflecting a second portion of the secondary air from the burner nozzle.
