The dumped heat from captive industry like power generation plant, steel plant, refineries, etc. has tremendous potential for multiple energy effect like cooling, power and heating effect. The novel thermodynamic system has been invented for waste heat recovery (WHR) purpose as organic Rankine cycle, kalian thermal system, etc. The recuperator type heat exchanger (HEx) can support for WHR at category of medium and high-grade heat discharge. The design and operating parameters of recuperator is essential for complete development and its thermodynamic analysis. The proposed title of research deals with the heat transfer modeling using LMTD & NTU approach with the help of MATLAB R2017 analytical tool. And ANSYS is used for design work of mentioned heat exchanger. The major outcomes of this paper are maximizing the heat transfer rate, improve overall efficiency by operating parameters, and HEx effectiveness. The shell and tube material, diameter, number of turns of tubes.
