Abstract
Sposób zwiększenia sprawności obiegu cieplnego siłowni, zwłaszcza dla tzw. "suchych" czynników roboczych charakteryzuje się tym, że pompa zasilająca (IV) zwiększa ciśnienie cieczy roboczej i podaje ją do regeneratora (VI), gdzie kosztem ciepła odbieranego od przegrzanej pary czynnika roboczego (który już przepracował w ekspanderze izotermicznym) następuje proces podgrzewania czynnika roboczego, a następnie para z regeneratora (VI) kierowana jest do wymiennika wysokotemperaturowego (V), gdzie zwiększa się jej temperatura kosztem ciepła przekazanego od czynnika grzewczego (np, spalin), a po wyjściu z wymiennika wysokotemperaturowego (V) czynnik dopływa do ekspandera izotermicznego (I) (np. turbiny izotermicznej), gdzie doprowadzane jest ciepło ze źródeł zewnętrznych, a czynnik ekspanduje przy stałej lub prawie stałej temperaturze i oddaje przy tym moc do napędu generatora elektrycznego (II), a następnie czynnik roboczy dopływa do regeneratora (VI), w którym oddaje swoje ciepło do podgrzewania czynnika roboczego, a następnie z regeneratora (VI) czynnik wpływa do skraplacza (III) i wykrapla się, a powstałe skropliny dopływają do pompy (IV) i cykl się powtarza.A way to increase the efficiency of the thermal cycle of the power plant, especially for the so-called "dry" working media is characterized by the fact that the feed pump (IV) increases the pressure of the working liquid and feeds it to the regenerator (VI), where at the expense of heat removed from the superheated steam of the working medium (which has already been worked in the isothermal expander) the process of heating the working medium occurs and then the steam from the regenerator (VI) is directed to the high-temperature exchanger (V), where its temperature increases at the expense of the heat transferred from the heating medium (e.g. flue gas), and after leaving the high-temperature exchanger (V) the medium flows to the isothermal expander ( I) (e.g. isothermal turbine), where heat is supplied from external sources, and the agent expands at a constant or almost constant temperature, and gives power to drive the electric generator (II), and then the working medium flows to the regenerator (VI), in which he gives up his heat to heat the working medium and then from the rege nerator (VI) factor flows into the condenser (III) and condenses, the resulting condensate flows into the pump (IV) and the cycle repeats.
