Objectives: This review explores the rationale of using waste heat energy from hot exhaust gases, hot water & hot steam to improve efficiency of systems. Methods: Since the amount of non-renewable sources is limited, there is unmet need to develop systems which utilize nonrenewable sources or waste energy (reusable) sources. Energy recovery systems (i.e. heat pumps & exchangers) of waste-to-energy units represent a substantial part which utilizes waste energy to increase thermal as well as electric power of whole system. Findings: Waste water can be considered as a reusable key energy source. Because of the higher thermal efficiency, combined cycle power plants are striking options based on this technology for generation of power as compared to individual gas or steam turbine cycles. Along these lines, the ideal outline of such cycles is of incredible noteworthiness inferable from expanding fuel costs and diminishing fossil fuel assets. Improvements: As a consequence, cost of product can be optimized and environment can also be protected.
