Abstract:
1. A power generation system featuring enhanced efficiency through the inclusion of a reheat heat exchanger, comprising in combination: a high temperature high pressure source of working fluid; a reheat heat exchanger having a high pressure inlet downstream from said high temperature high pressure source of working fluid, a high pressure outlet, a low pressure inlet, a low pressure outlet, a high pressure path between said high pressure inlet and said high pressure outlet and a low pressure path between said low pressure inlet and said low pressure outlet, said high pressure path located in heat transfer relationship with said low pressure path; an expander having an inlet downstream from said high pressure outlet and a discharge, said expander adapted to expand the working fluid therein from a higher pressure to a lower pressure; said discharge of said expander upstream from said low pressure inlet of said reheat heat exchanger; and wherein said source of working fluid is a source of a mixture of substantially only steam and carbon dioxide.
