Definitions

  • Anchor blocks for a steam turbine in an electric power plant are embedded in a concrete foundation supplied by the customer.
  • the anchor blocks are provided with keying portions utilized to maintain axial and transverse alignment of one or more cylinders or casings of the turbine units and the generator driven by.the turbine.
  • L-shaped liners are snugly fitted between the keying portions of the anchor blocks and lugs on the turbine casing, also the generator frame.
  • the stationary parts, namely, the turbine casings and the generator, of a turbine installation are not rigidly bolted to the customers foundation.
  • Axial and transverse movement, due to thermal gradients during normal operation of an elastic fluid turbine, has been controlled by anchoring seating plates to the foundation and then utilizing keys to maintain the required alignment between the seating plates and the turbine casings and the generator frame.
  • An object of this invention is to simplify the alignment of a turbine and generator assembly on a fixed foundation.
  • Another object of the invention is to provide for maintaining the assembly in position after it has been aligned.
  • the purchaser of a steam turbine builds a concrete foundation for the turbine and generator assembly.
  • Transverse anchor blocks are cast into the foundation at substantially the axial centerline of the turbine. Upwardly extending projections on the blocks extend above seating plates bolted to the foundation to support the turbine low-pressure cylinders or casings.
  • L shaped liners are fitted between the anchor blocksand lugs on the casings and the generator frame to maintain coaxial alignment of the turbine casings and the generator.
  • the anchor blocks also serve as axial keys for the low-pressure cylinder bases by being fitted directly to the bases instead of the seating plates.
  • FIG. 3 is a view, similar to FIG. 2, showing the manner ofinstalling the transverse anchor block, the seating plate and the turbine casing in accordance with the present invention.
  • FIG. 4 is an enlarged isometric view of one of the liners utilized in the installation.
  • the apparatus shown therein includes a steam turbine cylinder or casing 10 and a portion of an electric generator 11 driven by the turbine.
  • the casing 10 may be a low-pressure unit of a compound turbine including one or more low-pressure units and a high-pressure unit (not shown) connected to each other in tandem through which high-temperature steam flows before entering the low-pressure unit.
  • the casing 10 and the generator 11 are mounted on a concrete foundation 12. As shown more clearly in FIG. 3, the casing 10 is supported on a steel seating plate 13 which may be secured to the foundation 12 by a plurality of bolts 14 embedded in the foundation 12.
  • the stationary parts of a steam turbine installation namely, the turbine cylinders or casings and the generator are not rigidly bolted to the customer's foundation.
  • movement, axial and transverse, due to the thermal gradients in the normal operation of elastic fluid turbines has been controlled by anchoring seating plates to the foundation and then utilizing keys to maintain the required alignment between the seating plates and the casings and the generator.
  • FIG. 2 which is representative of the prior art, a customer of a turbine manufacturer has been required to install steel backing plates 15 in the foundation 12 to the correct centerline and elevation during the construction stages of the foundation.
  • the manufacturer has supplied transverse anchor blocks 16 (only one being shown) which are bolted and doweled to the backing plates 15 by means of a plurality of bolts 17 and dowel pins 18.
  • a keyway 19 is shown in the seating plate 13 for receiving one of the axial keys previously utilized in the installation.
  • the prior method of installation has caused a customer considerable concern because of the difficulty in maintaining the backing plate at the correct elevation and in a level plane during the construction of the foundation.
  • the bolting and doweling of the anchor block to the backing plate in the field is an expensive operation, since the backing plate must be drilled in place to receive the anchor block.
  • the backing plates previously utilized are eliminated, together with the drilling and doweling, and the transverse anchor blocks 16 are cast in the foundation 12 during its construction.
  • an anchor block 16 is disposed at one end of the casing 10 and a similarblock 16a is disposed at the other end of the casing.
  • the anchor blocks are substantially on the axial centerline L-L of the turbine. It will be understood that an additional anchor block may be provided at the other end of the generator 11 and an additional block would also be provided at the other end of another low-pressure turbine casing when utilized.
  • the block 16 has a keying portion 21 which extends upwardly past the seating plate 13 and between a pair of transversely spaced, axially extending projections or lugs 22 on the turbine casing 10.
  • the lugs 22 are formed integrally with the base ofthe casing 10.
  • the anchor block is similar to the block 16 except that at least the keying portion of block 16a is of sufficient thickness axially to extend between axially extending lugs 23 on the frame of the generator 11 and the neighboring lugs 22 on the turbine casing 10, thereby enabling the one block 160 to cooperate with both the turbine casing 10 and the frame of the generator 11 to maintain them in coaxial alignment.
  • the block 16 would be of sufficient thickness axially to extend between lugs 22-on the adjacent casing of the additional turbine unit.
  • the projections 21 are of narrower width than the spacing between the associated lugs 22 to facilitate alignment, and after final alignment of the equipment, snug-fitting L-shapecl liners 24 are fitted in the gaps between the anchor blocks and since sufficient clearance 27 is provided between the anchor block and the baseof the turbine casing to accommodate thermal expansion of the casing.
  • the anchor block herein described serves as an axial key for the turbine casingsince it is fitted directly to the casing instead of to the seating plate, as in prior constructions.
  • the steel backing plates and the difficulties of installing them are eliminated by utilizing the transverse anchor blocks in the manner herein described.
  • said projections formed in pairs at opposite ends of said casing and being in spaced relation in a plane transverse to the axial centerline of said casing,
  • said blocks having keying portions extending upwardly above the seating plate and between said projections, to thereby facilitate alignment of said casing.
  • each liner is L-shaped with one leg retaining the liner in position.
  • At least one of said blocks cooperating with the generator frame to retain it in coaxial alignment with the turbine casing.
