Conceptual and preliminary design of waste heat recovery system using organic rankine cycle(ORC)

Nowadays according to increasing energy consumption and also with respect to accurate using fuels resources and reducing pollutants emission to the atmosphere; The topic of accurate using of energy and dealing with its waste have an extraordinary importance. For this reason, one of the cycles are being studied is Organic Rankine Cycle, it is practical for accurate energy consumption and recovering it, which consequently cause of reducing pollutants emission to the atmosphere. The Organic Rankine Cycle is one especial type of Rankine Cycle, operating at the super low temperature in compared to Rankine Cycle. This wide range of operating temperatures causes of that we can use it for recovering waste heat from cycles with low operating temperature, for instance: Biomass, Solar Energy, Geothermal and even Industrial Plants waste heat. In this research, tried to give some general acquaintance for this cycle, its importance study, the necessity of using it and also experiences of foreign countries about it. Moreover, the plan of conceptual and primary design of this cycle based on costumer’s desires as pioneer research will be presented.
