Abstract:
Investigations on the increasing of efficiency of steam turbine cycle have been carried out by many Research centers of universities and turbine production concerns already for a few dozen of years. In the case of thermodynamic cycles with applied steam turbines, the investigations have dealt with steam pressure and temperature.
This research studying the influence of the regenerative closed feed water heaters on operational costs of steam power plant stations can be determined by means of the incremental energy efficiency of total system the presented method proves energy a very high efficiency of the steam cycle, the analysis of the influence of feed water heaters on investment expenditures of the plant, would be more difficult by normal method (calculation).
