Waste Heat Recovery explores the potential of thermophotovoltaics (TPV) for capturing and utilizing industrial heat losses, focusing on improving energy efficiency and sustainability. The book highlights how TPV systems can convert waste heat into usable electricity, offering a solution to the significant energy and economic losses from unharnessed thermal energy. One intriguing aspect covered is the detailed engineering considerations for deploying TPV systems, including the design of emitters and cells for optimal efficiency, alongside case studies from industries like steel manufacturing and cement production. This book uniquely provides a detailed analysis and economic evaluation of TPV systems, moving beyond theoretical discussions to offer practical guidance for implementation.

It begins by introducing the fundamental concepts of thermodynamics, semiconductor physics, and radiative heat transfer, essential for understanding TPV systems. The book then progresses to examining specific industrial sources of waste heat, modeling system performance, and analyzing economic viability, concluding with a discussion of future trends and challenges in TPV research.
