Description
The main goal of the project is to verify the feasibility of Organic Ranking cycle in the temperature range associated with the motor circuit shirts with an overall 10% higher system in a prototype installation of 25kW of electrical power. This will foresee a minimum improvement in energy efficiency of 10% in these types of facilities. Although initially the project will be focused on the peninsular maritime industry, it is expected within 3 years to have an international dimension. In the second screening phase it is expected to introduce in terrestrial application sectors, because this system is basically applicable to any hot spot from 85ºC onwards. The project will look into potential cogeneration applications that only use exhausts (dryers, brick, etc.), condensate extraction combined cycle cooling systems of large compressors, absorption and adsorption chillers, cement, glass furnaces, melting furnaces, arched, steel mills, refineries, etc.
Summary of project results
INTEGASA has tried to solve supply problems on ships, avoiding energy waste coming from flue gases, refrigeration and radiation. So the main goal of ENERGY NAV has been to validate Rankine Organic Cycle on the range of temperatures associated to motor shroud with global efficiency over 10% in a prototype of 25KW. INTEGASA has designed a parametrical system, marking the critical points and defining efficiency strategies, and also testing refrigerating fluids suitability. INTEGASA has also defined economic rates, escalating the system even to 150KW. Project's outcome has been a prototype of ENERGY NAV tested on land. INTEGASA has tried to find a shipowner to validation phase but failing to it they selected ENERBASQUE plant as the perfect environment to make the tests, even better that their own facilities, thanks to ENERBASQUE'S hot source, so INTEGASA team moved several times to Vitoria, and at the end of 2015, Madre Carmela ship showed interest to test ENERGYNAV
