Combustion device

A combustion device, comprising:

• a combustion chamber having an exhaust gas opening, said combustion chamber being configured to have a first region formed as a deflecting region of a gas flow and having a plurality of circular-segment-shaped cross-sections in parallel relationship, each circular-segment-shaped cross-section having a circular centre point, with a connection of the circle centre points lying substantially on an axis, wherein a side wall of the combustion chamber is formed in the first region as part of a jacket surface of a rotational body which defines a rotational axis, said axis extending substantially along of the rotational axis of the rotational body;
• a gas supply line connected to the combustion chamber such as to form orifice arranged on a bottom side of the combustion chamber in an operating position, with gas supplied via the gas supply line flowing against the first region tangentially from below and transversely to the axis,
• said combustion chamber having a mixing region in a region of the orifice for thorough mixing of gas supplied via the gas supply line with gas rotating in the combustion chamber,
• said combustion chamber including in a region of the orifice of the gas supply line a second region with V-shaped cross-section tapering towards the orifice, with the mixing region being part of the second region, said second region being arranged tangentially adjacent to the first region so that a tangential flow against the first region is formed along the side wall.

A method for operating a combustion device with a combustion chamber, comprising:

• conducting a gas flow into the combustion chamber from below through an orifice of a gas supply line arranged on a bottom side of the combustion chamber;
• mixing the gas flow that flows in from the gas supply line with a gas rotating in the combustion chamber in a mixing region arranged in a region of the orifice;
• conducting the gas flow tangentially from below and transversely to an axis against a first region of the combustion chamber, which first region is formed as a deflecting region of a gas flow and comprises a plurality of circular-segment-shaped cross-sections in parallel relationship to each other, with each circular-segment-shaped cross-section having a circular centre point, wherein a connection of the circular centre points substantially lies on the axis;
• forming a side wall of the combustion chamber in the first region as part of a jacket surface of a rotational body, with the axis extending substantially along a rotational axis of the rotational body;
• deflecting the gas flow in the first region about the axis, with the combustion chamber having in the a of the orifice of the gas supply line a second region with V-shaped cross-section tapering towards the orifice, with the mixing region being part of the second region;
• forming a tangential flow against the first region along the side wall by arranging the second region tangentially adjacent to the first region;
• and
• discharging the gas flow via an exhaust gas opening.
