Waste heat recovery technologies and applications

Waste Heat Recovery Technologies In Turbocharged Automotive Engine – A Review

Significant waste heat recovery technologies have been developed to recover exhaust heat and turn it into useful energy such as in downsizing the engine or to regain the auto-electricity. Extensive work and research in energy recovery have been identified in the automotive sector; therefore the main objective of this paper is to assess each waste heat recovery technology based on current develo...

A feasibility study and economic analysis for application of nanofluids in waste heat recovery

This paper presents a comprehensive theoretical, experimental, and economic study on the application of nanofluids as heat transfer fluid in waste heat recovery systems. The research work was conducted in a steel-making complex in which a plate heat exchanger had been used to recover heat from hot process water. The system was theoretically modelled and the effects of using nanofluids as he...

An algorithm for optimal waste heat recovery from chemical processes

We describe a computer algorithm designed to calculate the optimal energy extraction in the form of heat used for steam raising from chemical processes. The concepts are illustrated using chemical plant stream data in a process with multiple distillation columns. Pinch analysis is first applied to find the grand composite curve (GCC) of the problem, which is then used by the algorithm to determ...
