1. 1. Techno-Economic Analysis of Organic Rankine Cycles for a Boiler Station : Energy system modeling and simulation optimization

   University essay from Uppsala universitet/Institutionen för fysik och astronomi

   Author : Jamel Hudson; [2019]
   Keywords : Organic Rankine cycle; ORC; Working fluids; Boiler station; District heating system; Simulation model;

   Abstract : The Organic Rankine Cycle (ORC) may be the superior cycle for power generation using low temperature and low power heat sources due to the utilization of high molecular mass fluids with low boiling points. They are flexible, simple, easy to operate and maintain, and offer many possible areas of applications including waste heat recovery and power generation from biomass, geothermal and even solar energy.

4. 3. Perspectives for Power Generation fromIndustrial Waste Heat Recovery

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Fanny Blanquart; [2017]
   Keywords : ;

   Abstract : This thesis work was carried out at Siemens in Germany in the department of Steam Turbines, and aims to raise awareness of the potential for broader deployment of waste heat recovery (WHR) from industrial processes for power generation. Technologies available to recover heat are presented and sorted out according to the features of the heat source. READ MORE

5. 4. Rankine Cycles, Modeling and Control

   University essay from Lunds universitet/Institutionen för energivetenskaper

   Author : Ylva Teleman; [2016]
   Keywords : dynamic; modeling; organic rankine cycles; Modelica; simulation; Dymola.; Rankine cycles; Technology and Engineering;

   Abstract : As the demand for decreased use of energy increases, new ways of using energy sources are investigated. One of these ways is to be able to use low temperature heat sources, which can be done with a rankine or organic rankine cycle. READ MORE

6. 5. Comparative Study of Different Organic Rankine Cycle Models: Simulations and Thermo-Economic Analysis for a Gas Engine Waste Heat Recovery Application

   University essay from KTH/Kraft- och värmeteknologi

   Author : Tihomir Rusev; [2015]
   Keywords : ORC; Waste Heat Recovery; Aspen Plus; Cascaded Cycle; Thermo-Economic; ORC Simulations; ORC Models; ORC Model Comparisons; Gas Engine Waste Heat Recovery; Hot Exhaust Gases; Multiple Waste Heat Sources; ORC Waste Heat Power Generation; Heat and Power; Combined Cycle; Siloxane;

   Abstract : Increasing the efficiency of conventional power plants is a crucial aspect in the quest of reducing the energy consumption of the world and to having sustainable energy systems in the future. Thus, within the scope of this thesis the possible efficiency improvements for the Wärtsilä 18V50DF model gas engine based combine power generation options are investigated by recovering waste heat of the engine via Organic Rankine cycle (ORC).
