Aceh as one of Indonesian province has some hot springs potencies that can be utilized to generate electricity by organic Rankine cycle (ORC) system. This paper discusses energy and exergy assessment of ORC with hot spring as the heat source in Aceh, Indonesia. Energy and exergy assessment are utilized to evaluate ORC performance. The performance are evaluated from the hot springs that have temperature...
This paper presents the electricity power potency estimation from hot spring in Indonesia with temperature 70-80°C using Organic Rankine Cycle (ORC). ORC is a system that able to generate electricity with a low heat source temperature, making it suitable to be used to generate electricity with hot spring as heat source. Organic fluid is used as working fluid in the system. Temperature and volume flow...
Plate spacing is one of variable that influences plate heat exchanger (PHE) design as a condenser in Organic Rankine Cycle (ORC) system. The rises of plate spacing have effects to channel cross sectional area, channel velocity, equivalent diameter, and Reynold number at hot and cold fluid sides in PHE. Those parameters affect the total heat transfer area and total pressure drop that influence the...
