Most of the energies are utilized by the industries, due to depletion of fossile fuels and increasing the fuel price to utilize the maximum available energy from the waste heat source. The study is conducted in the turbine exhaust of the sugar cogeneration plant. From this study determine amount of heat energy is lost from turbine exhaust and it condensate in the condenser. The turbine exhaust heat energy is converted to cooling effect using vapour absorption refrigeration system and to replace the vapour compression refrigeration system. From the study, energy consumption and energy savings in terms of energy and fuel are analyzed. © 2012 Published by Elsevier Ltd.
