Bahram Saadatfar, Reza Fakhrai and Torsten Fransson, JMES Vol 2 Issue 1 2014 the OFC on waste thermal energy recovery at 300 °C by using isentropic and dry fluid is studied by Ho et al. [38]. Fig. 12 (a) OFC layout (b) T–s diagram of the OFC [116] There are different modifications to enhance the efficiency of the OFC systems. The double flash OFC, split the flash evaporation cycle into two steps, and then more fluid is vaporized results in more power production [116]. Presently reported available isentropic efficiency for radial inflow turbine around 70% in two phase regime [117], allows potentially replace throttling valve, and achieving higher efficiency with designing two-phase OFC. A twin-screw machine for two-phase expansion with isentropic efficiencies of about 70% is tested by Smith et al [118]. It was presented that OFC showed higher heat addition exergetic efficiency comparing the other vapor cycles, but on the other hand the throttling process showed a drawback. The OFC also potentially offers exploiting thermal energy sources at lower temperatures. 3. Future directions in Low-Temperature waste heat recovery Directly transfer heat from the waste heat source to the evaporator without an intermediate heat transfer loop is one of the current research areas. This will reduce the cost around 15% and thermal mass of the system. It can reach the 20%-40% increase in ORC efficiency [119]. However some issues surrounding the selection of an ORC working fluid such as safety and flammability. In addition the constraints imposed on the thermodynamic analysis and heat exchanger design also important. One of the waste heat sources is exhaust gases. However, low temperature recovery from gas streams containing chemicals becomes increasingly challenging. These waste heat sources will have limitations for cooling flue gases to low temperatures. Hence, developing of heat exchangers for working in such corrosive environments is under research and development. Another area for research is heat exchangers with larger heat transfer coefficients which help to reduce the heat transfer area. Some examples of available heat technology are ceramic inserts used in radiant heating tubes and finned tubes. 14PDF Image | Thermodynamic Vapor Cycles for Converting Low- to Medium-grade Heat to Power: A State-of-the- art Review and Future Research Pathways
