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

摘要： 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.
