ABSTRACT:
A combustion liner for a gas turbine combustion apparatus is composed of a series of ceramic wall rings coaxially aligned from the upstream to the downstream end of the liner. The ceramic rings are connected so as to be free to expand radially relative to each other while maintaining alignment. One type of connection between the rings involves notches distributed around the ends of a ring and bosses distributed around the adjacent end of the next ring entering into the notches. Another type of interconnection involves notches distributed around adjacent ends of two ceramic rings with a metal ring disposed between them having bosses which engage in some of the notches to align the parts. The liner is supported by supports at the ends of the liner from an outer casing. One support includes a spring to accommodate relative expansion of the liner and outer casing. A hot wire type fuel igniter disposed around the fuel nozzle of the combustion apparatus is energized by a circuit through the compression spring with return to the grounded casing through the fuel nozzle.
