SYSTEM AND METHOD FOR MONITORING A COMBUSTOR

摘要

A combustor nozzle includes a center body that defines an axial centerline. A shroud circumferentially surrounds at least a portion of the center body to define an annular passage between the center body and the shroud. A plenum is inside the center body and aligned substantially parallel to the axial centerline. A sensor extends inside the center body and is generally adjacent to the plenum, wherein the sensor detects a condition proximate to the combustor nozzle. A method for monitoring a combustor includes flowing a fuel through a center body axially aligned in a nozzle and flowing a working fluid through an annular passage substantially parallel to and radially outward of the center body. The method further includes sensing a condition inside the combustor using a sensor located inside the center body.
