摘要: A forced draft burner apparatus for burning a gaseous fuel while producing low levels of NOx, CO and hydrocarbon emissions comprising: cylindrical inner having tubular wall; generally body mounted inside the wall burner; an annular flow channel (110) being defined between said section, constituting throat oxidant gases, downstream outlet means (102, 106) supplying gases to divergent quarl (116) its smaller end connected burner, exiting into combustion chamber; plurality curved axial swirl vanes (112) in impart flowing throat; gas injection provided proximate injecting at point upstream end; outer surrounding least portion including spaced from define (120) channel; providing (104, 108); (126, 128) channel, end.
