A gas turbine combustion including a combustion wall having a plurality of generally cylindrical passages therein which extend around and are generally parallel to, the chamber axis, each of said passages having a series of air inlets disposed along the passage and tangentially directed thereinto, generally towards the center of the chamber, and means for directing cooling air into the series of air inlets in each passage to set up a forced vortex therein. The series of air inlets may be arranged to set up forced vortices of opposite rotation in adjacent passage. A means for directing cooling air into the tube inlets may comprise an annular shroud which extends around the air inlets and directs airflow into the air inlets.
