发明名称 Combustion chamber for gas turbine engine
摘要 In a combustion chamber consisting of a first stage (1) and a second stage (2) arranged downstream in the direction of flow, a mixer (100) is arranged on the head side of the first stage (1), which mixer (100) forms a fuel/air mixture (19). Acting on the outflow side of this mixer (100) is a catalyzer (3) in which the said mixture (19) is completely burnt, the mixing being selected in such a way that an adiabatic flame temperature of between 800 DEG and 1100 DEG C. arises. Positioned on the outflow side of this catalyzer (3) are vortex generators (200) which provide for a turbulent flow. Downstream of these vortex generators (200), fuel (9) is injected and self-ignition initiated. A following jump (12) in cross section in the cross section of flow of the combustion chamber, which jump (12) in cross section forms the start of the second stage (2), provides a stabilizing backflow zone of the flame front (21).
