Oxy-fuel burner

Method of designing a burner for combusting fuel with an oxidizer containing at least 23%vol O 2 , the block of the burner defining in succession a feed passage, a substantially cylindrical burner chamber having a length Lc and optionally a widening terminal section having a length Ls, so that Lc/(L...

Summary:Method of designing a burner for combusting fuel with an oxidizer containing at least 23%vol O 2 , the block of the burner defining in succession a feed passage, a substantially cylindrical burner chamber having a length Lc and optionally a widening terminal section having a length Ls, so that Lc/(Lc + Ls) > 2/3 and 30mN ‰¤ 0,5*(ˆ‘If + ˆ‘Iox)* [(Lc + Ls) 2 /So] ‰¤ 70mN, whereby ˆ‘If and ˆ‘Iox are the total fuel respectively oxidizer injection momentum at nominal power and So is the cross sectional area of the outlet opening of the block in the plane perpendicular to the burner axis.
