AbstractBlast furnaces are essential departments that consuming the largest energy amount in integrated iron and steel factories. Blast furnaces consist of many vital subsections for survival of iron and steel production. Hot stoves are fundamental auxiliary subsections of blast furnaces consuming fuel and providing hot air into blast furnaces. In this study heat recovery and energy saving potential of hot stoves were investigated and new heat recovery possibilities were recommended. For this purpose, energy production costs per unit energy, specifications of hot stoves construction and fuel components were received from Kardemir A. Ş. blast furnace management. Three heat recovery options were considered in order to determine optimum heat recovery device in terms of energy recovery, saving and investment cost.
