In this article, the first and second law analysis of diesel engine based cogeneration system was performed. Fuel utilization efficiency, rate of power, and rate of process heat of the plant were determined and various efficiencies based on both energy and exergy methods and the performance assessment parameters are defined for both the system components and the entire cogeneration plant. The o...
Currently, the feasibility to replace standard efficiency electric motors with higher ones is assessed considerations differing from real operating conditions in industry. This study compares of replacing 26 (IE1) high-efficiency (IE2 and IE3) a sugar plant, based on three different energy scenarios considering incremental costs or depreciated motors. Energy scenario 1 consider that operate for...
