Abstract
As a means of heat recovery in marine field as well as in land industrial processes, the use of waste heat boilers to generate steam which derives conventional steam turbine, in turn, drive electrical generator is well-known technique. While, in many potential waste heat applications, the gases or liquids which function as the heat source are relatively low temperature levels. It is hardly possible to operate an efficient and simple Rankine Cycle engine using steam as the working fluid with these low heat source temperature. One of the attractive features of a Rankine Cycle with Organic working fluid is its ability to operate efficiently with low temperature heat source, which permits use of various low grade energy source have not been effectively harnessed in the past. This Organic Rankine Cycle System is based on the use of Fluorinol-85 as a working fluid. In addition to desirable thermodynamic characteristics, use of this fluid has the following primary advantages relative to steam cycle waste heat recovery system
•Substantially higher power output
•High conversion efficiency
•Simple and compact turbine design
