In this study, the power generation evaluation from residual industrial heatwere analyzed using source heat temperature (150-225) ^oC and mass flow rate of heat source about 300 kg/s. A mathematical model was developed according to turbine and pump power as well as the heat add and rejected from the evaporator and condenser with regard to the ambient temperature effects and superheated temperature effects on the performance of Rankine cycle system. The performance of the system was evaluated under six working fluids (Ammonia, Propane, Water, Benzene, R245fa and n-pentane) divided between wet and dry fluids. Can be seen from result that the superheated temperature is good effects for wet fluids but is bad effects on dry fluids which is the net power and thermal efficiency increasing with increase the superheated temperature. Also for produce more power from the Rankine cycle system we need more heat source. As well as the effect of increasing of ambient temperature on the performance of Rankine cycle system is bad especially in summer session. The value of thermal efficiency was between 7.46 and 21.4 for the six fluids selected. Water was the better performance between all working fluids selected. Finally the results is compared with the literature and the agreement is good.
