The present invention relates to a burner system, in particular for a gas turbine, with a main supply channel (2), debouching into a combustion chamber (1), for a fuel/air mixture having a swirler (5) and a burner lance (3) which passes through the swirler (5). To improve the transverse ignition properties between several such burner systems, optionally disposed on the burner chamber (1), and also to increase the flame stability, the burner lance (3) has, on the combustion chamber side with respect to the swirler (5) exit openings (12, 16) for fuel supplied to its interior or for a fuel-rich fuel/air mixture supplied to, or formed in, its interior.

A burner system for a gas turbine, comprising: a combustion chamber; a main supply channel debouching into the combustion chamber; a swirler arranged in the main supply channel; a burner lance extending through the swirler; a fuel channel provided in the interior of the burner lance, said fuel channel having first exit openings leading radially outwardly into the combustion chamber; a premix chamber provided in the interior of the burner lance; a combustion air channel provided in the interior of the burner lance; said fuel channel and said combustion air channel debouching into the premix chamber via debouchement openings; second exit openings from the premix chamber leading axially outwardly into the combustion chamber; said premix chamber being an annular chamber, wherein the second exit openings are distributed about the circumference of the premix chamber; and said first exit openings being dimensioned in relation to the debouchement openings extending into the premix chamber such that a majority of the fuel supplied to the combustion chamber emerges through the first exit openings.
