The author discusses the exact relationships obtained for the optimum distribution of heater enthalpy rises in a contact heater train for the simple regenerative subcritical cycle, the single reheat cycle with one and several heaters at and above the reheat point, and also for the double reheat cycle. The problem of supercritical cycles and the method of taking exact account of the influence of the feed pumps are also discussed.
