Double wall combustion chamber for a combustion turbine

Abstract From the Canadian patent

This invention describes a double wall stepliner construction for a combustion chamber of a combustion turbine. The chamber is a series of concentric cylindrical segments stacked in overlapping arrangement such that the leading edge of each outer segment and the terminal edge of each inner segment are in general axial alignment so as to form a continuous double wall throughout the axial length of the step-liner configuration. Each cylindrical segment is attached at its inlet end and at its outlet end to the adjacent cylindrical segment by an annular transition member formed of a wire mesh secured to each respective cylindrical segment with high temperature brazing. The relative thermal …
