Gas turbine combustor

A gas turbine combustor in a configuration having a plurality of combustors, each combustor including a combustion chamber having an annular combustion air passage on an outer periphery thereof, one of the combustors being connected with adjacent other combustor by a cross fire tube assembly, the adjacent other combustor being ignited by the cross fire tube assembly, wherein:

• the cross fire tube assembly has a dual pipe configuration including an inner tube that connects the combustion chambers of the adjacent combustors and an outer tube that covers therein the inner tube and connects the combustion air passages of the adjacent combustors;
• openings are formed between the inner tube and the outer tube on each of outer peripheral partition walls of the combustion air passages that are each connected with the outer tube of the cross fire tube assembly, the openings allowing combustion air to flow in areas upstream and downstream of the inner tube with respect to the flow of the combustion air flowing through the combustion air passages;
• and
• guide plates are disposed upstream of the inner tube, the guide plates guiding the combustion air into a space inside the outer tube via the opening.
