Pump: Compression of the fluid to high pressure using a pump (this takes work) (Figure 2: Steps 3 to 4) Boiler: The compressed fluid is heated to the final temperature (which is at boiling point), therefore, a phase change occurs—from liquid to vapor. The cycle also has regeneration by passing extracted steam through closed feedwater heaters to warm up the water and improve cycle efficiency. The organic Rankine cycle (ORC) uses an organic fluid such as n-pentane [1] or toluene [2] in place of water and steam. Demonstrate the Sankey class with a practical example of a Rankine power cycle.
