Abstract
Tracking the performance of extraction, back-pressure
and condensing steam turbines is a crucial
part of minimising energy and maintenance costs for
large process industries. A thorough understanding
of key equipment performance characteristics
promotes economical in-house power generation.
Proper Scheduling of maintenance reduces
downtime. Rankine Efficiency as a function of
steam flow can be accurately predicted from several
sources of available data. Sample analysis of
predicted performance data (Willans Line, flow
versus extraction enthalpy, flow versus exhaust
temperature and flow versus used energy) and test
data are presented. Techniques for deriving
efficiency curves from each source are described.
These techniques can be applied directly to any
steam turbine reliability study effort.
