METHOD OF LOW NOX COMBUSTION AND BURNER DEVICE FOR EFFECTING SAME

A method of low-NOx combustion and a burner device for effecting the same, in which a primary fuel (F1) is injected in a direction from the periphery of stream of a combustion air (A) towards that same combustion air, effecting a first combustion, so as to create a generally cylindrical primary flam...

Zusammenfassung:A method of low-NOx combustion and a burner device for effecting the same, in which a primary fuel (F1) is injected in a direction from the periphery of stream of a combustion air (A) towards that same combustion air, effecting a first combustion, so as to create a generally cylindrical primary flame (B1) covering the combustion air, whereby a secondary fuel (F2) injected towards the combustion air is shielded or intercepted by such primary flame from the combustion air, while causing NOx in the primary flame to be reduced by the secondary fuel, after which, a second combustion is effected by bringing the secondary fuel to contact with a portion (A') of the combustion air penetrating through the primary flame, at a downstream side. This arrangement permits more positive decrease of NOx density in an exhaust gas.
