Abstract (en)
[origin: WO9502789A1] A forced draft burner apparatus for burning a gaseous fuel while producing low levels of NOx, CO and hydrocarbon emissions; comprising: an outer shell (8) including a windbox and a constricted tubular section (13) in fluid communication therewith; a generally cylindrical body (16) mounted in said shell coaxially with and spaced inwardly from said tubular section; an annular flow channel being defined between said body and the inner wall of said tubular section, said channel constituting a throat (14) for oxidant gases provided thereto from said windbox, and having a downstream outlet end for said gases; means for providing a flow of said oxidant gases to said throat from said windbox; a divergent quarl (28) being adjoined to said outlet end of said throat and defining a combustion zone for said burner; a plurality of curved axial swirl vanes (20) being mounted in said annular flow channel to impart swirl to said oxidant gases flowing downstream in said throat; fuel gas injection means being provided in said annular flow channel proximate to said swirl vanes for injecting said gas into the flow of oxidant gases at a point upstream of said outlet end.
