1. Method for generating a plasma flame (21) with a plasma combustion gas blown out in a plasma flame direction (8) through a plasma flame opening (6) from a plasma combustion chamber (2), wherein the plasma combustion chamber (2) is at least partially arranged in a cavity resonator (4) and microwave energy is supplied to the cavity resonator (4) via a waveguide (5) to generate a plasma in the plasma combustion chamber (2), and wherein a swirl generating device (9) is used to inject a swirl gas into the plasma combustion chamber (2) in order to generate a swirl gas jacket surrounding the plasma flame (21) in the plasma combustion chamber (2), which jacket shields a plasma combustion chamber wall (3) made of a dielectric solid material from the plasma flame (21), wherein the plasma combustion chamber wall (3) protrudes in both directions along the plasma flame direction (8) beyond the cavity resonator (4) and is fixed in each case at a distance from the cavity resonator (4) in a plasma combustion chamber wall support (10), wherein the plasma combustion chamber wall support (10) comprises at least one support cooling cavity (11) through which a coolant flows.
