Abstract

 

After a presentation of the functionality of steam turbines of thermal power plants, we present the method of enthalpy difference used for the calculation of the steam turbine efficiency. This is why we present a stratification survey by circuit, by equipment and by organ. The objective is to determine the possible reasons for the deterioration of the heat rate of a thermal power plant at the level of a steam turbine. This survey concerns particularly the application of the causal analysis for determining the different losses at the level of a steam turbine.

 

Key words: Thermal power plant, steam turbine, efficiency calculation, causal analysis.
