COMBUSTION TURBINE ENGINE COMBUSTOR BASKET IGNITER PORT ALIGNMENT VERIFICATION TOOL AND METHOD FOR VALIDATING IGNITER ALIGNMENT

摘要

A combustion turbine engine combustor igniter port alignment and dimensional verification tool is insertable in guide tube and igniter boss portions of the igniter port. The tool has concentrically nested outer and inner sleeves, having respective circumferential profiles that are separately slidably insertable within corresponding igniter port guide tube and igniter boss portions that have inner circumferential profiles in conformance with minimal dimension specifications. Concentric alignment of the guide tube and igniter boss is validated by inserting the nested outer and inner sleeves into the igniter port. The verification tool is capable of validating igniter port alignment and dimensions before the combustor is installed in a combustion turbine engine.
