Abstract
An apparatus and method for using staged air combustion. The apparatus includes a burner body () secured to a port block (), and a fuel passageway () extending through the burner body (), terminating in a fuel nozzle (), which injects fuel into the burner throat (). Primary air jets () are configured to inject primary air into a primary combustion region (), which is normally in the burner throat (). A dish with a dish surface () is connected to the burner throat (); the dish surface () extending in a divergent angle with respect to a burner centerline (). Secondary air jets () are connected to the air passageway () and extend through the port block (). The secondary air jets () inject secondary air into a secondary combustion region (), which may be at the dish surface () or the hot face () of the burner.
