A system and method for configuring a steam turbine to accommodate changing resource conditions, such as may be encountered with geothermal wells. A plurality of sets of nozzle/blade assemblies are provided for installation in a diaphragm structure and on a rotor, respectively. As the condition of steam provided to the turbine changes, a different set of nozzle/blade assemblies may be installed to maintain a preferred thermodynamic efficiency for the turbine.

A seal segment for a turbine is provided having labyrinth teeth and a brush seal disposed along the labyrinth teeth. A plurality of the segments for a seal ring. The segments are separable from each other so that the seal can retract. Each segment has two ends, each of which abuts another segment, with those ends lying along a radius (when looking down the shaft of the turbine). The brush disposed in each segment has ends that do not lie along a radius, but fit together in a tongue and groove configuration when the seal segments come together to form a seal.

The axial flow turbine has an asymmetrical flow input, for example, at the first nozzle plate and which flow is attenuated towards an axi-symmetric flow by a baffle plate located between the first nozzle plate and the second stage. The baffle plate directs the flow towards a more symmetrical flow pattern before permitting the flow to pass through the second stage. Consequently, the long turbine blades in the later stages of the turbine respond to an attenuated asymmetrical flow rather than a larger asymmetrical flow which might induce vibrations or vibrations at the natural resonant frequency of the turbine blading which could break the turbine blades.
