Abstract
An improved debris tolerant seal for a rotary combustor is disposed on the inlet end ring header so as to extend radially inwardly therefrom and cooperates with a parallel spaced apart surface and diverging surface on an adjacent refractory ring to form a seal which will not become jammed with waste materials and allows for radial and axial thermal expansion of the rotary combustor.
