ABSTRACT:
This disclosure pertains to wall burners which are used to raise the temperature of a gas stream flowing through a duct. Wall burners are mounted outside the duct and fire into the duct through a porthole formed in the duct wall. The present invention is uniquely characterized by a pre-main combustion chamber wherein a combusting fuel-air mixture is generated using only a small amount of the total fuel expended by the burner. The combusting mixture travels downstream through an accelerator ring and into the duct at high velocity and momentum. On the downstream side of the accelerator ring, main fuel ports inject the major portion of the fuel expended into the combusting fuel-air mixture whereupon a transfer of heat and momentum takes place which carries the unburned main fuel into the duct where the main combustion process takes place.
