    • PROBLEM TO BE SOLVED: To provide a method, system and apparatus relating to a reheat combustion turbine engine with exhaust gas recirculation.SOLUTION: A method is configured to control a power plant that includes a working fluid and a recirculation loop. The power plant has an upstream combustor operably connected to a high-pressure turbine, and a downstream combustor operably connected to a low-pressure turbine. The method includes: recirculating the working fluid through the recirculation loop; controlling an amount of compressed oxidant supplied to each of the upstream combustor and the downstream combustor; controlling an amount of fuel supplied to each of the upstream combustor and the downstream combustor; controlling the power plant such that each of the upstream combustor and the downstream combustor periodically operates at a preferred stoichiometric ratio; and selectively extracting the working fluid from a first extraction point associated with the upstream combustor and a second extraction point associated with the downstream combustor based upon which of the upstream combustor and the downstream combustor operates at the preferred stoichiometric ratio.

    • PROBLEM TO BE SOLVED: To adjust the axial center line position of a bearing structure as intended.
      SOLUTION: An axial center adjusting intervening object (26-V, H) is interposed between a body stage (18) and a bearing (22) supported by the body stage (18). The axial center adjusting intervening object (26-V, H) consists of a first adjusting body (26-V) and a second adjusting body (26-H). The first adjusting body (26-V) comprises a first tapered surface (27) which moves the bearing (22) in the first direction relative to the body stage (18) by moving the first adjusting body (26-V) in the first direction. The first tapered surface (27) is a joining surface between the first adjusting body (26-V) and the bearing (22). The second adjusting body (26-H) comprises a second tapered surface (28) which moves the bearing (22) in the second direction relative to the body stage (18) by moving the second adjusting body (26-H) in the second direction. The moving position is rigidly maintained as two-dimensional fine movement is accurately adjusted as intended. No gear cutting adjustment is required.
