What is the difference between the Kalina cycle and the Rankine cycle?
At present, the Kalina cycle and organic Rankine cycle (ORC) are the most widely studied cycles that can utilize low-grade and waste heat sources (see Section 1.5). A standard Kalina cycle uses a mixture of ammonia and water, while the conventional organic Rankine cycles utilize organic substances.
What is the difference between Kalina and ORC?
The ORC applies the principle of the steam Rankine cycle, but it uses organic working fluids with low boiling points to recover heat from lower temperature heat sources. Also, in the Kalina cycle, ammonia water is selected as the working fluid because of its variable boiling point and thermodynamic properties.

What is the organic Rankine cycle?
An Organic Rankine Cycle (ORC) system is a closed thermodynamic cycle used for power production from low to medium-high temperature heat sources ranging from 80 to 400°C and for small-medium applications at any temperature level.
What is Q in Rankine cycle?
The water vapor with condensed droplets often seen billowing from power stations is created by the cooling systems (not directly from the closed-loop Rankine power cycle). This "exhaust" heat is represented by the "Qout" flowing out of the lower side of the cycle shown in the T–s diagram below.
