摘要

Results obtained from calculations of the economic effect gained from using a two-stage delivery-water heating arrangement in a 40-MW steam turbine unit for a combined-cycle plant are presented. It is shown that the use of the two-stage arrangement makes it possible to produce additional electric power due to an increase in the steam turbine output by as much as 1.5 MW in comparison with the system containing one delivery-water heater; the outlays for additional equipment are paid back in a relatively short period of time.
