Abstract
Official abstract text for this publication.
A method is disclosed of disassembling a gas turbine which includes a combustor, a liner, a turbine vane carrier (TVC) and an outer housing, the method including disengaging the liner from the TVC and removing the TVC from the gas turbine. The liner is disengaged from the TVC before the TVC is removed, the liner remains inside the outer housing and the combustor remains in the outer housing.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of disassembling a gas turbine having a combustor, a liner, a turbine vane carrier and an outer housing, the method comprising: attaching a support structure to support a portion of the liner proximate the turbine vane carrier prior to disengaging the liner from the turbine vane carrier, disengaging the liner from the turbine vane carrier and removing the turbine vane carrier from the gas turbine, wherein the liner is disengaged from the turbine vane carrier before the turbine vane carrier is removed, and wherein the liner remains inside the outer housing and the combustor remains in the outer housing. 2. The method of claim 1 , wherein the combustor remains in the same position relative to the outer housing, and the liner moves relative to the combustor. 3. The method of claim 1 , comprising: removing a turbine housing and/or removing an exhaust gas housing (EGH), before the turbine vane carrier is removed. 4. The method of claim 1 , comprising: moving the liner using jacking screws or a rail system after the liner is disengaged from the turbine vane carrier. 5. The method of claim 1 , wherein after being disengaged the liner is supported by the support structure, the support structure being attached to another part of the gas turbine. 6. The method of claim 5 wherein the support structure is attached to the outer housing, a rotor cover and/or the combustor.
