Sažetak
Steam turbine for the main feed water pump (MFP) drive is a low power turbine, for which energy power losses and energy efficiency analysis are presented in this paper. The MFP steam turbine analysis has been performed within a wide range of turbine loads. The influence of steam specific entropy increment of the real (polytropic) steam expansion upon the MFP turbine energy power losses and energy efficiency has been investigated. During all the observed loads MFP steam turbine energy power losses were in the range between 346.2 kW and 411.4 kW. The MFP steam turbine energy power losses and energy efficiency were most significantly influenced by the steam specific entropy increment. Change in the steam specific entropy increment is directly proportional to the change in MFP turbine energy power losses, while the change in the steam specific entropy increment is reversely proportional to the MFP turbine energy efficiency change. For the observed turbine loads, the MFP steam turbine energy efficiency was in the range between 46.83% and 51.01%.
