COMBUSTOR AND METHOD FOR REDUCING THERMAL STRESSES IN A COMBUSTOR |
摘要 |
A combustor includes first and second annular casings with a joint between the first and second annular casings. A flow sleeve surrounds a combustion chamber to define an annular passage, and an annular shield inside the first annular casing extends downstream from the joint and prevents a working fluid flowing through the annular passage from contacting at least a portion of the first annular casing. A method for reducing thermal stresses in a combustor includes flowing a working fluid from a compressor through an annular passage between a combustion chamber and a flow sleeve inside the combustor, shielding the working fluid flowing through the annular passage from contact with at least a portion of a joint between first and second annular casings, and shielding the working fluid flowing through the annular passage from contact with at least a portion of the first annular casing downstream from the joint.
