6.8 Steam Turbine Construction Forms
6.8.2 Industrial Steam Turbines
Figure 6.29 represents an industrial condenser turbine of reaction type, with steam
extractions. Variants exist with backpressure. The turbine shown has an equilibrium
piston at the left-hand side in the figure. Such turbines are single-casing machines
with power ranging from as low as 100 kW (single-stage; low admission pressure)
to around 250 MW with admission pressure up to about 150 bar. Applications are
mechanical drive of turbo-compressors (natural gas pipelines) and large pumps
