Design and Simulation of Recuperator for Hot Stoves
In this study a unique recuperator was designed in order to increase the combustion air temperature entering into
hot stove for recovering the heat from flue gas of hot stoves. Recuperator thermal calculations were performed for different
flow arrangement to determine the most profitable flow option in terms of heat transfer surface area (AR), recovered heat
and investment cost. At the second step, Mr. Strelow’s static simulation model was used to determine the outlet temperatures
of hot and cold flows and temperature distribution in entire recuperator for the steady state condition independent from time
variable for different flow arrangements. Results of the simulations were demonstrated via curves and evaluated in terms of
heat transfer rate, outlet temperatures and required AR.
