In this study, a gas to gas heat exchanger (recuperator) was designed to increase combustion air temperature entering hot stoves by recovering the heat of flue gas released from hot stoves. Firstly, thermal calculations were done for different flow arrangement to determine the most efficient flow option in terms of heat transfer surface area (AR) and recovered heat (QR). In second step, a static simulation method was utilized to determine outlet temperatures of hot and cold flows and temperature distribution in entire recuperator for steady state condition for different three case studies. Thirdly economical calculations were
performed to monitor total savings (E) of three case studies. Overall, 2823 kW thermal energy and 95 377 $ economic saving potential was discovered by application of a heat recovery system to conventional hot stoves in our study.
