摘要： The invention relates to a combustion system (1) with a in the direction of alongitudinal axis (L) inside a peripheral wall (3) of a combustion chamber (10) extendingthe combustion chamber (2) within which in use, a recirculation flow with largely recycledby an inner recirculation zone exhaust gas formed and the input side is provided by acircumferentially with supply ports (46) for combustion air and fuel end wall (40) islimited and the outlet side an outflow opening (31) and having a burner head (4) via whichcombustion air and fuel via common supply ports (46) are partially premixed or throughseparate supply ports (46) separately into the combustion chamber (10) supplied,wherein the supply ports (46) in an annular arrangement in the outer region of the endwall (40) closer to the circumferential wall (3) than to the longitudinal axis (L ) located, arearranged and wherein the radius of the outflow opening (31) at least as large as theradial spacing of the feed openings (46) from the longitudinal axis (L). A stable over awide operating range combustion is achieved in that the combustion chamber (10) andthe burner head (4) are designed such that a recirculation rate is in the operating statebetween 0.4 and 1.5.
