Abstract

Power consumption highly
increases which is related with the growing of the industrial plants and daily
using. Increasing power demand can be supplied with building up more efficient
plants or optimized old power plants. One of the most important items of a
power plant is steam turbine which is designed according to defined parameters
(inlet pressure and temperature, flow rates, outlet pressure and power) which
also effect the dimensions and performance of the turbine. Turbine loses and
irreversibilities are minimum and so efficiencies and power generation are
maximum at design conditions. However, power plants always have to operate at
off-design or part-load conditions because of the changing of power demands and
drop outs of the turbines and other items of the plants. In this study, it is
aimed to analyses the isentropic efficiency of a high pressure steam turbine
and thermal efficiency of power plant at different load conditions. Analyses
showed that both steam turbines and power plant performance were reduced when
the power plant operates at partial load conditions.

Keywords
