Abstract
A combustor for a stationary combustor turbine is provided with a generally tubular sidewall formed from a telescopic arrangement of sidewall ring members. A corrugated spacer band supports the upstream end portion of each sidewall member on the downstream end portion of the next inwardly located sidewall member in the upstream direction. An annular coolant admission slot is thus provided between the sidewall members with the corrugated spacer band located therein. The downstream end portion of each sidewall member extends as an annular lip projecting downstream from the downstream end of the corrugated band to discourage mixing of the hot internal gases with the coolant air flowing as a film through the slot and along the inner sidewall surface. Thermal load is transmitted from the inner sidewall member through the corrugated band to the upstream end portion of the outer sidewall member where a slotted wall structure enables outer wall deflection which in turn permits radial growth of the inner sidewall member and its extended lip substantially without disturbing the slot coolant flow.
