Abstract (en)
[origin: DE4427222A1] A thermal shield (6) for the head area of a combustion chamber has as usual a through-hole (5) for the burner. A continuous collar (14) with air passage holes (16) projects from the back side of the thermal shield at the edge of said through-hole. Cooling air can flow through said holes into a ring-shaped channel (15) arranged between the thermal shield and the burner, then into the combustion chamber. This cool air flow lies as a cool air film on the surface of the thermal shield. For that purpose, the cool air flow or cool air film whirls in the same direction as the combustion air supplied through the burner. To generate this whirling motion, the air passage holes in the collar are inclined in the radial direction. The thermal shield is further provided with appropriate inclined effusion holes (19).
