ABSTRACT:
A wall burner is described for firing a flame laterally into a duct of the type generally known as a waste heat recovery duct wherein hot exhaust gases are passed in a heat exchange relationship with a second fluid downstream from the wall burner. The wall burner may be used as an igniter for a grid burner system disposed within the duct or the wall burner may itself be used to reheat the hot exhaust gases. The wall burner includes a combustion chamber pipe and ignition means located outside the duct so that ignition occurs outside the duct thereby obviating instabilities inherent in trying to ignite a combustible mixture within the hot exhaust gas path.
