Abstract (en)
[origin: US4575332A] To allow liquid and/or gaseous fuels to be burned with decreased NOx formation, the combustion air is fed in at axial intervals one after the other. The percentage of primary air is higher than that of secondary air. The injector effect of the primary air draws flue gas out of the firebox and supplies it to a flame-initiation point between the primary-air and secondary-air feeds.
