1998 Conceptual Design of Ocean Thermal Energy Conversion (OTEC) Power Plants in Sri Lanka
In 1994, NARA [National Aquatic Resources Research and Development Agency, Sri Lanka] investigated the ocean thermal resources in the sea off Sri Lanka. In this paper, ten suitable sites within the sea off Sri Lanka are investigated and conceptual design for a 100MW floating-type OTEC power plant is proposed. Optimum conditions are determined and plant specifications are computed using ammonia as working fluid and plate type heat exchanger in the evaporator and condenser. As a result, Rankine cycle efficiency is from 3.44 to 3.66 and a net power is about 70% of the gross.
