Oil burner for NO{HD x {b emission control

摘要: Method and apparatus for producing heat from a liquid fuel in an oil burner with low NOx-gas effluent. A small relatively higher velocity stream of air is directed concentric about divergent spray or ignited primary flame zone such amount that only minor portion the can be combusted said zone. The manner as to produce toroidal fluid circulation pattern atomizing establishing stable flame. recirculated flue gas (RFG) immediately thereafter introduced concentrically general direction flow. Air thereabout secondary flow path at least sufficient quantity burn remaining combustibles. Oxides nitrogen resultant effluent are suppressed by adjusting RFG hence composition temperature.
