A counter flow combustor for regenerative open cycle turbine systems has an outer casing defining a head cavity at one end, an inner casing mounting in said outer casing, said inner casing defining a combustion chamber. An annular insulated partition and support means is connected at its upper end to the inner wall of the outer casing and at its lower end to the discharge outlet end of the inner casing, said inner casing including a cooling and metering wall assembly about the secondary combustion zone having cooling means communicating at one end with a head cavity extension space and at the other end with the secondary combustion zone for delivering heated combustion air thereto and support means on the insulated partition and support means operatively connected to the cooling and metering wall assembly to hold the same in assembled position in the combustor. The cooling and metering wall assembly is formed from a plurality of circumferentially disposed shaped and formed sections serially connected to each other, each respectively having a cooling means therein, said cooling means having a plurality of inlets in communication with the head cavity extension space, and in communication with a slotted exit means formed by an inner wall shaped skirt on the cylindrical formed section. Said assembly also has a plurality of circumferentially disposed supporting struts to prevent the circumferentially shaped and formed sections from collapsing due to thermal stresses arising from pressure and temperature differential in the secondary combustion zone of the combustor.
