Thermodynamic analysis of the partially evaporating trilateral cycle [PDF]
, 2013 The potential of Organic Rankine Cycles (ORC) to recover low grade waste heat is well known. The high heat recovery potential is partially attributed to a good match of the temperature profiles between working fluid and waste heat stream in the ...

Exergy analysis and optimisation of waste heat recovery systems for cement plants
International Journal of Sustainable Energy, 2018 In the last decades, heat recovery systems have received much attention due to the increase in fuel cost and the increase in environmental issues. In this study, different heat recovery systems for a cement plant are compared in terms of electricity ...

A comparison of heat transfer correlations applied to an Organic Rankine Cycle
Engineering Science and Technology, an International Journal, 2018 Organic Rankine Cycles (ORC) are often based on the utilization of special dry or isentropic fluids, namely substances with a vertical or positive slope of the saturated steam curve.Several heat transfer correlations for boiling process are available in ...
