Buoyancy organic Rankine cycle
Renewable Energy, 2011Abstract In the scope of renewable energy, we draw attention to a little known technique to harness solar and geothermal energy. The design here proposed and analyzed is a conceptual hybrid of several patents. By means of a modified organic Rankine cycle, energy is obtained utilizing buoyancy force of a working fluid.

Heat Recovery Using Organic Rankine Cycle
Vestnik MEI, 2021Heat losses in industrial processes can be divided into three sections (high-, medium-, and low-temperature heat), depending on the temperature of the exhaust gases. This heat is usually recovered either by heat exchangers or by a closed Rankine cycle. However, about 60% of low-temperature heat losses remain irreplaceable.

Optimizing Energy Conversion Using Organic Rankine Cycles and Supercritical Rankine Cycles
ASME 2011 5th International Conference on Energy Sustainability, Parts A, B, and C, 2011The optimization of energy conversion systems is of great significance in the utilization of low-grade heat. This paper presents an analysis of 6 working fluids in 12 thermodynamic cycles to optimize the energy conversion systems. The optimal exergy efficiency of the system is dependent on the type of the thermodynamic cycle, the choice of appropriate ...

Organic Rankine Cycle as Bottoming Cycle to a Combined Brayton and Clausius - Rankine Cycle
Key Engineering Materials, 2013A preliminary evaluation has been made of a possibility of bottoming of a conventional Brayton cycle cooperating with the CHP power plant with the organic Rankine cycle installation. Such solution contributes to the possibility of annual operation of that power plant, except of operation only in periods when there is a demand for the heat.

Comparison of a Basic Organic Rankine Cycle and a Parallel Double-Evaporator Organic Rankine Cycle
Heat Transfer Engineering, 2016ABSTRACTThe applications of zeotropic mixtures and multi-evaporator systems are two viable options to improve the performance of the organic Rankine cycle (ORC). This paper conducts the thermo-economic comparison of a basic ORC with R245fa/R600a and a parallel double-evaporator organic Rankine cycle (PDORC) with R245fa.

Optimization of Overcritical Organic Rankine Cycle
Applied Mechanics and Materials, 2016This paper explores the optimization cases for overcritical Organic Rankine Cycle (ORC) in various situations. First the ORC optimization in terms of working fluid selection is discussed. In this case, thermal efficiencies for 10 different working fluids have been calculated under certain temperature frames and the results are compared.

Chap. 3 is dedicated to Rankine cycles with organic fluids: the so-called organic Rankine cycles (ORC), which in recent years have had a large success on the market. After a brief historical review we discuss the characteristics that must have the potential working fluids to be used in an ORC engine. A large discussion is about the interactions between

Technical options for Organic Rankine Cycle systems
2017The plant components and the plant configurations adopted in the Organic Rankine Cycle (ORC) field differ appreciably from the solutions used in large steam cycles because of the different nature of the working fluid and the type of heat source. ORCs are rarely fueled by fossil fuels, they usually work at relatively low temperatures, and they are ...
