Abstract
In this paper an approximate method of analysis is developed to compare the performance of single-pump and split-pump schemes in the non-reheat regenerative steam cycle. The analytical result is shown to agree closely with figures obtained by detailed calculations based on the same standards of comparison of the two schemes as those used in the approximate analysis, although on an alternative basis of comparison the calculated difference between the performances of the two schemes is smaller. The study reveals, however, that on either basis of comparison the efficiency of the cycle is slightly greater for the split-pump arrangement. Detailed calculations for a typical reheat cycle show the same tendency. It is concluded that, on the score of both thermal efficiency and capital cost, the split-pump arrangement is to be preferred.
