Energy has played important role to create the world as we observe it today. Fossil fuels account for the most of the world’s energy consumption, but they have been estimated to be finite sources because the rate of resource usage is much higher than the rate of discovery of new reservoirs. Due to rapid consumption of fossil fuel resources and their environmental impact, the world is being challenged to shift the energy dependence from fossil fuel. New energy conversion technologies are required to effectively utilize energy resources suitable for power generation without causing environmental pollution an organic Rankine cycle (ORC) used to recover waste heat to produce additional power. WHR using ORCs involves potential use, the utilization of the sensible enthalpy of the hot exhaust to heat an organic fluid, preferably to saturated or superheated vapour, and then the energy of the vapour is used to obtain additional useful power from a small turbine. Organic Rankine cycle (ORC) technology has been identified as one of the most promising technologies in recovering low-grade heat sources there is an essential demand for using sustainable and renewable energy systems for an energy production in the future. This paper mainly concentrates on the power production and increasing efficiency by recovering waste heat from steam power plant using Organic Rankine Cycle (ORC). This paper also had a discussion of using a reheating and preheating process in ORC to increase the output of cycle by using a Aspen HYSYS V9 package.
