In this ongoing paper, it is expected to look at the three basic organic Rankine cycle (ORC) structures with a zeotropic mixture which consists toluene and xylene, used as the working medium. The study included basic ORC in addition, ORC with internal heat exchanger and ORC with feed heater. Each configuration is analysed with zeotropic mixture at mass fraction of 50% to obtain certain parameters related energy like, evaporator temperature, net workdone and efficiency of distinct organic Rankine cycle configurations. Analysis shows that organic Rankine cycle with feed heater is the most proficient among every other configuration and shows the maximum efficiency at 25 pressure ratio be 19.73%. Additionally, organic Rankine cycle with feed heater will deliver the maximal workdone, which is 17.18% and 8.01% higher than the Basic and Recuperative, consecutively.

摘要

In this ongoing paper, it is expected to look at the three basic organic Rankine cycle (ORC) structures with a zeotropic mixture which consists toluene and xylene, used as the working medium. The study included basic ORC in addition, ORC with internal heat exchanger and ORC with feed heater. Each configuration is analysed with zeotropic mixture at mass fraction of 50% to obtain certain parameters related energy like, evaporator temperature, net workdone and efficiency of distinct organic Rankine cycle configurations. Analysis shows that organic Rankine cycle with feed heater is the most proficient among every other configuration and shows the maximum efficiency at 25 pressure ratio be 19.73%. Additionally, organic Rankine cycle with feed heater will deliver the maximal workdone, which is 17.18% and 8.01% higher than the Basic and Recuperative, consecutively.
