Thermodynamic Simulations of Exergy Efficiency in Organic Rankine Cycle (ORC) Based on Exergy System
Keywords:
Gasification, Pyrolysis, Combustion, Thermodynamic simulation, Exergy efficiencyAbstract
Exergy analysis in a biomass-powered cycle is vital, especially when involving thermo-chemical conversion technologies like gasification and Pyrolysis. These involve complex analyses and have comparative advantages to combustion techniques in power generation. This study conducted a thermodynamic simulation of the exergy efficiency of a novel Organic Rankine Cycle (ORC) with turbine bleeding for tri-generation to ascertain the optimal intrinsic values and their real-time boundaries for efficient power output. The study employed a replication method with a developed soft template written source code in Engineering Equation Solver (EES) compared to inconsistent and untactful productivity identified with energy-sapping blue-collar analysis of the system that was invoked hitherto, using three working fluids: R245fa, R1234yf and R1234ze bounded by environmental and safety standards, and valuable temperatures, pressures and mass flow rates. The results showed that exergy efficiencies for R1234ze, R245fa and R1234yf were recorded as 29.61%, 28.34% and 22.32% respectively. In contrast, the generic ORC without turbine bleeding with the same configuration had corresponding respective efficiencies of 13.25%, 15.33% and 14.06%, which were relatively low, particularly with respect to ORC system without cooling, and having respective efficiency improvement of 16.36%, 13.0%1 and 8.26%. Additionally, the total output power was 201.0KW for R245fa, 162.5 KW for R1243ze and 131.7 KW for R1234yf having Turbine Inlet Temperatures (TITs) spread between 90-120°C in general. Based on the evaluated thermodynamic properties and their output, especially enthalpy, entropy and exergy destruction, R234fa is given preference, with the highest overall efficiency, followed by 1234ze then 1234fy in that order. The designed ORC system has the potential for medium temperature relevance with agricultural wastes and for biomass energy utilisation with reduced vent gases compared to most ORC systems used for low-grade heat sources such as geothermal and solar applications, which are wasted as thermal pollution.
