Abstract
The boiler nose or arch of a furnace projects into the upwardly flowing flue gas to form a restricted passage. Overfire air is introduced into the cavity or plenum of the boiler nose and flows to injection ports along the inclined surface of the boiler nose to provide overfire air for penetration into and mixing with the flue gases in the restricted flue gas passage.
