Method Of Salvaging Stationary Blades Of A Steam Turbine
US Patent:
4819313, Apr 11, 1989
Filed:
Jun 3, 1988
Appl. No.:
7/201715
Inventors:
Ghanshyam M. Dadhich - Orlando FL
Assignee:
Westinghouse Electric Corp. - Pittsburgh PA
International Classification:
B21K 300
US Classification:
291568R
Abstract:
A method of salvaging stationary blades of a steam turbine cylinder includes tack welding abutting stationary blade platforms, cutting stationary blade roots out of the steam turbine cylinder, machining a side of the root and platform for each stationary blade to reduce thickness along the side and mounting the stationary blades in a new cylinder having mounting grooves for each row of stationary blades. Each mounting groove has an annular recess formed in a sidewall thereof and the cylinder has a sloping surface which faces a machined area of the root and platform of the stationary blades. The space between the sloped surface and the machined area provides access for a piece of caulking material and a caulking tool, whereby the caulking material is deformed to make a key connection between the cylinder and the stationary blade roots.
