Abstract
A nozzle segment separation tool for use with a pair of adjacent nozzle segments in a casing of a turbine. The nozzle segment separation tool may include a pair of support plates, a hydraulic cylinder positioned within the pair of support plates, a pushing bar attached to the hydraulic cylinder, a nozzle catch plate positioned within the pair of support plates, and a blocking pin inserted through the casing. The blocking pin forces the nozzle catch plate to engage a first nozzle segment of the pair of adjacent nozzle segments and blocks movement of the pushing bar such that the nozzle catch plate separates the pair of adjacent nozzle segments.

A nozzle segment separation tool for use with a pair of adjacent nozzle segments in a casing of a turbine, comprising:
- a pair of support plates;
- a hydraulic cylinder positioned within the pair of support plates;
- a pushing bar attached to the hydraulic cylinder;
- a nozzle catch plate positioned within the pair of support plates;
- and
- a blocking pin inserted through the casing;
- wherein the blocking pin forces the nozzle catch plate to engage the a first nozzle segment of the pair of adjacent nozzle segments and blocks movement of the pushing bar such that the nozzle catch plate separates the pair of adjacent nozzle segments.
A method of separating a pair of adjacent nozzles in a casing of a turbine, comprising:
- sliding a nozzle segment separation tool about the pair of adjacent nozzles;
- inserting a blocking pin through the casing;
- forcing a nozzle catch plate of the nozzle segment separation tool into contact with one of the pair of adjacent nozzles by the blocking pin;
- engaging the blocking pin with a pushing bar of the nozzle segment separation tool;
- and
- pulling the one of the pair of adjacent nozzles by the nozzle catch plate.
