ABSTRACT:
A method and apparatus for feeding a bulk material supplemental fuel through a port formed in a side wall of a rotary vessel of a cement kiln. The apparatus includes a stationary annular plenum surrounding rotary vessel. The plenum is configured to define an enclosed interior region in communication with the port in the rotary vessel. The apparatus also includes a bulk material fuel charging apparatus including a hopper for receiving the bulk material, and a barrel in communication with the hopper. The barrel has an open discharge end extending into the interior region of the annular plenum. The bulk material fuel charging apparatus also includes an air cannon in air flow communication with the barrel for injecting air into the barrel to force a portion of the bulk material located in the barrel out of the open discharge end of the barrel, through the port, and into the rotary vessel.
