Abstract
A radial lip of a high temperature combustor liner is mechanically locked in a radially directed capture slot in a supporting shell of a combustor. In one embodiment, the capture slot is formed at abutting edges of shell sections which are joined by a weld bead. The weld bead is accessible for grinding off to provide access to the liner for replacement. In embodiments in which a plurality of liner sections are employed, a downstream end of a liner section overlaps and shields an upstream end of an adjacent liner section including the radial lip thereof to protect the radial lip and capture slot from temperatures in the combustion zone and to channel a sheet flow of film cooling air along an inner surface of the adjacent liner. Positioning bosses may be included between adjacent liner sections for centering.
