1. A combustion chamber of a gas turbine comprising: an outer combustion chamber wall;tiles attached to an inner side of the outer combustion chamber wall;a slot positioned in a center area of the combustion chamber relative to a flow direction and extending around an entire circumference of the combustion chamber, the slot physically separating the outer combustion chamber wall and the tiles into a front part and a separate rear part for supplying mixing air, the front part and the rear part being separately mounted to the gas turbine, the slot including an outlet, the outlet opening toward a radial center of the combustion chamber, a flow path of the slot at the outlet being directed toward the radial center of the combustion chamber to direct the mixing air from the outlet toward the radial center of the combustion chamber;a plurality of combustion chamber arms separately mounting the front part of the combustion chamber and the rear part of the combustion chamber, the combustion chamber arms having through-flow openings, wherein a through-flow opening most adjacent to a combustion chamber head provides the slot with at least a portion of the mixing air. 2. The combustion chamber in accordance with claim 1, wherein the slot is shaped as at least one chosen from straight, wavy and having a varying cross-section around the circumference. 3. The combustion chamber in accordance with claim 1, and further comprising a front combustion chamber arm for mounting the front part and a rear combustion chamber arm for mounting the rear part, the front part and the rear part attached to the front combustion chamber arm and rear combustion chamber arm respectively to vary a cross-sectional flow area at an exit of the slot due to thermal expansion or contraction. 4. The combustion chamber in accordance with claim 3, wherein the cross-section flow area of the slot is variable. 5. A combustion chamber of a gas turbine comprising: A single wall combustion chamber;a slot positioned in a center area of the combustion chamber relative to a flow direction and extending around an entire circumference of the combustion chamber, the slot physically separating the outer combustion chamber wall into a front part and a separate rear part for supplying mixing air, the front part and the rear part being separately mounted to the gas turbine, the slot including an outlet, the outlet opening toward a radial center of the combustion chamber, a flow path of the slot at the outlet being directed toward the radial center of the combustion chamber to direct the mixing air from the outlet toward the radial center of the combustion chamber;a plurality of combustion chamber arms separately mounting the front part of the combustion chamber and the rear part of the combustion chamber, the combustion chamber arms having through-flow openings, wherein a through-flow opening most adjacent to a combustion chamber head provides the slot with at least a portion of the mixing air. 6. The combustion chamber in accordance with claim 5, wherein the slot is shaped as at least one chosen from straight, wavy and having a varying cross-section around the circumference. 7. The combustion chamber in accordance with claim 5, and further comprising a front combustion chamber arm for mounting the front part and a rear combustion chamber arm for mounting the rear part, the front part and the rear part attached to the front combustion chamber arm and rear combustion chamber arm respectively to vary a cross-sectional flow area at an exit of the slot due to thermal expansion or contraction. 8. The combustion chamber in accordance with claim 7, wherein the cross-section flow area of the slot is variable.
