A Comprehensive review respect to Waste heat recovery finds that IC engine exhaust contains heat with sufficient energy to justify implementation of a secondary cycle. Among the different cycles, ORC''s are the most commonly implemented WHR systems in order to generate power from low-grade to medium-grade waste heat.

Der Organic Rankine Cycle gleicht – bezogen auf die einzelnen Komponenten – dem klassischen Clausius-Rankine-Kreisprozess. Die wesentlichen Unterschiede liegen in den Prozessparametern Druck und Temperatur – beide liegen weit unter den Werten, wie sie in Dampfkraftwerken herrschen – und in der Abweichung der Verdampfung und der …
As shown in the previous right figure, the ORC cycles are used with hot sources of very different temperatures from 100 to 350 C approximately. Above 350 C, the steam cycles are generally more efficient, and below 100 C, except in exceptional cases such as OTEC cycles or solar ponds, the cycle efficiency is so low that the conversion into mechanical …

After a brief historical review we... By way of a further example, in the sector of renewable energy, several forecasts agree on the enormous potential for exploiting the …
In the case of wet steam, the actual entropy can be calculated with the vapor quality, x, and the specific entropies of saturated liquid water and dry steam: s4 = sv x + (1 – x ) sl. where. s4 = entropy of wet steam (J/kg K) = 5.89 kJ/kgK. sv = entropy of "dry" steam (J/kg K) = 8.227 kJ/kgK (for 0.008 MPa)
