This manuscript presents an advanced exergo-economic analysis of a waste heat recovery system based on the organic Rankine cycle from the exhaust gases of an internal combustion engine. Different operating conditions were established in order to find the exergy destroyed values in the components and the desegregation of them, as well as the rate of fuel exergy, product exergy, and loss exergy. The component with the highest exergy destroyed values was heat exchanger 1, which is a shell and tube equipment with the highest mean temperature difference in the thermal cycle. However, the values of the fuel cost rate (47.85 USD/GJ) and the product cost rate (197.65 USD/GJ) revealed the organic fluid pump (pump 2) as the device with the main thermo-economic opportunity of improvement, with an exergo-economic factor greater than 91%. In addition, the component with the highest investment costs was the heat exchanger 1 with a value of 2.769 USD/h, which means advanced exergo-economic analysis is a powerful method to identify the correct allocation of the irreversibility and highest cost, and the real potential for improvement is not linked to the interaction between components but to the same component being studied.

Heat Recovery System

A waste heat recovery system for generation of electricity has been added to a natural gas pipeline compressor station. The heat recovery system, utilizing a dual pressure Rankine cycle with water/steam as the working fluid, increases the overall thermal efficiency of the 12,500 hp simple cycle gas turbine from 25.3% to 36.1%. The system will generate power for the local electric distribution system.

Probability Of Success

The DD-963 Class ships are the first U.S. Navy vessels to utilize a waste heat recovery system on a gas turbine engine. This paper will present the experience gained from the three years of shipboard operation with the system. The experience will be used to develop areas for consideration that can improve the probability of success in future system procurements. The areas to be considered are: (a) the need for definitive military specifications; (b) the need to test at Navy laboratories and (c) the need to test complete systems under simulated shipboard conditions.

Heat Recovery System

Waste heat recovery systems are used to recover the waste heat in all possible ways. It saves the energy and reduces the man power and materials. Heat pipes have the ability to improve the effectiveness of waste heat recovery system. The present investigation focuses to recover the heat from Heating, Ventilation, and Air Condition system (HVAC) with two different working fluids refrigerant(R410a) and nano refrigerant (R410a+Al2O3). Design of experiment was employed, to fix the number of trials. Fresh air temperature, flow rate of air, filling ratio and volume of nano particles are considered as factors. The effectiveness is considered as response. The results were analyzed using Response Surface Methodology
