Abstract:
A combustion system comprising:a burner body having a first fluid inlet end forming at least one primary first fluid inlet and a first fluid outlet end forming at least one first fluid outlet, said first fluid outlet oriented to deliver a first fluid to a combustion zone; an inner conduit disposed within said burner body and forming a fluid flow region between said burner body and said inner conduit, said inner conduit having a second fluid inlet distal from said first fluid outlet and a second fluid outlet proximate said first fluid outlet, said second fluid outlet oriented to deliver a second fluid to said combustion zone without first being mixed with said first fluid; internal adjustment means for adjusting a flow cross-sectional area of said first fluid disposed within said burner body; and internal pressure adjustment means for adjusting an internal pressure in said burner body, said internal pressure adjustment means comprising an interior wall disposed in said fluid flow region upstream of said first fluid outlet extending from an outer surface of said inner conduit to an inner surface of said burner body and forming at least one opening for enabling flow of said first fluid from said primary first fluid inlet to said at least one first fluid outlet, and at least one pressure altering blocking means disposed within said burner body suitable for altering flow of said first fluid through said at least one opening.
