Abstract
The present application provides a cross fire tube installation/removal apparatus for use with a combustor of a gas turbine engine. The cross fire tube installation/removal apparatus includes a cross fire tube assembly having a sleeve with a tube groove therein and a cross fire tube tool having a spring with a spring flange. The spring flange is sized to engage the tube groove.
Claims15
A method of installing a cross fire tube assembly between a first combustor can and a second combustor can, comprising:
- inserting a cross fire tube tool through a first passage in the first combustor can;
- engaging a tube groove in the cross fire tube assembly with a spring flange of the cross fire tube tool;
- compressing the cross fire tube tool with the cross fire tube assembly engaged;
- positioning the cross fire tube assembly in a second passage in the second combustor can;
- and
- releasing the cross fire tube tool.
A method of removing a cross fire tube assembly from between a first combustor can and a second combustor can of a gas turbine engine, comprising:
- inserting a cross fire tube tool through a first passage in the first combustor can;
- engaging a tube groove of the cross fire tube assembly with a spring flange of the cross fire tube tool;
- compressing the cross fire tube assembly via the cross fire tube tool so as to disengage a cross fire tube collar from a liner collar;
- and
- withdrawing the cross fire tube assembly and the cross fire tube tool from the first passage.
A method of preparing a cross fire tube tool for installation of a cross fire tube assembly in a combustor of a gas turbine engine, comprising:
- retracting a tubular spring within a reaction arm of the cross fire tube tool;
- locking the tubular spring in the retracted position within the reaction arm via a locking knob engaged with a locking knob aperture;
- inserting the cross fire tube tool through a passage in the combustor;
- and
- releasing the locking knob so as to permit the spring flange of the tubular spring to engage a tube groove of the cross fire tube assembly.
