Optimization of the heating surfaces of turbine reheaters at nuclear power stations

The results of optimization of minimal temperature differences δt in the stages of the reheater of a steam-turbine plant are presented as a function of a complex quantity that unites external and internal parameters, which are the initial data in calculations of thermal schemes; the results of optimization of δt for four steam-turbine plants at nuclear power stations are given; they can be used in developing new separators and reheaters.
