Abstract :In this study, heat transfer and cost optimization of a gas-to-gas heat exchanger insert ignore into journalissuearticles values(recuperator); operating in the targeted temperature range has been made. Firstly, the thermophysical properties of the waste heat source and the volumetric flow rates of the flows were obtained, and the maximum heat that could be recovered was obtained. Afterward, a parametric study was carried out to size the recuperator. The parameters affecting the cost, such as hot flow and cold flow outlet temperatures, were determined by the overall heat transfer coefficient, effectiveness, and pressure drop. Finally, the thermal parameters obtained from the parametric study are used in the technoeconomic analysis. The recuperator geometry with the maximum saving coefficient was determined considering investment and operating costs. As a result, the 108th simulation resulted in maximum savings with 653 252 $/year using 321.19 m2 heat transfer surface area.
