Abstract (en)
[origin: EP0845639A1] The chamber comprises a cross-sectional narrowing (30) in the flow direction which enables the transition of the hot gases (21) between the first stage (20) and the succeeding stage (40). The cross-sectional narrowing has a structure with the Mach number at the outlet (31) being equal to the surface ratio of the narrowing. The surface ratio is a quotient of the outlet surface (A2) over the inlet surface (A1). The axial length (L) of the cross-sectional narrowing is 5% greater than the diameter at the inlet surface. The combustion chamber is of the ring type and is operable with at least one pre-mix burner (10).
