Abstract:
Many industrial processes have low temperature heat losses and are generally ignored due to the lack of effective heat recovery methods. Ignoring these heat sources can cause heat pollution and damage to the environment. Using the low-temperature organic Rankine cycle (ORC) is a good solution to this problem. The main target of this research is to model and analyze the performance of two hybrid systems, gas turbine (GT), steam Turbine (ST) and solid oxide fuel cell (SOFC) with the hybrid GT, ORC and SOFC cycle (SOFC+ GT+ ORC) from the thermodynamic and exergy perspectives. Studies show that the output power of a combined system with a steam cycle is higher than that of a system with an organic Rankine cycle, but this higher output does not necessarily mean that this cycle is better. The use of a steam cycle at a higher power range and higher temperature of the inlet gases of turbine is more justified. The results show that the use of toluene fluid in the organic Rankine cycle among the analyzed fluids produces the most power at the condenser temperature of ۳۱۹ Kelvin.
