Methods of Increasing Net Work Output of Organic Rankine Cycles for Low-Grade Waste Heat Recovery
In heat engine design, the usual objective is to maximize thermal efficiency. However, for heat engines applied to waste heat recovery, an appropriate objective is to maximize power production by converting as much of the waste heat as possible into work. An organic Rankine cycle (ORC) is particularly well-suited to waste heat recovery because of its compactness relative to a steam Rankine cycl...
متن کاملThermo-Economic Analysis of Zeotropic Mixtures and Pure Working Fluids in Organic Rankine Cycles for Waste Heat Recovery "2279
We present a thermo-economic analysis of an Organic Rankine Cycle (ORC) for waste heat recovery. A case study for a heat source temperature of 150 ̋C and a subcritical, saturated cycle is performed. As working fluids R245fa, isobutane, isopentane, and the mixture of isobutane and isopentane are considered. The minimal temperature difference in the evaporator and the condenser, as well as the mi...
متن کاملSelection of the Optimum Working Fluids in Organic Rankine Cycles Using TOPSIS
Organic Rankine Cycles (ORC) can be used to convert low-grade waste heat to electricity. The working fluid employed in the ORC has a strong influence on the thermal efficiency of the system. Until now, methods for the selection of working fluids have been based on trial and error approaches which are not very effective. As a result, the motivation for the work reported in this paper is to remed...
متن کاملLow-Grade Waste Heat Recovery for Power Production using an Absorption-Rankine Cycle
An investigation of heat recovery for power generation using an absorption-Rankine cycle with a low temperature waste heat source was conducted. In such a cycle, the condenser and boiler of a conventional Rankine system are replaced with an absorber and desorber. A recuperative solution heat exchanger is also incorporated between the absorber and desorber to minimize the external heat input. An...
متن کاملDynamic modeling and optimal control strategy of waste heat recovery Organic Rankine Cycles
Organic Rankine Cycles (ORCs) are particularly suitable for recovering energy from low-grade heat sources. This paper describes the behavior of a small-scale ORC used to recover energy from a variable flow rate and temperature waste heat source. A traditional static model is unable to predict transient behavior in a cycle with a varying thermal source, whereas this capability is essential for s...
