| Abstract | The steel industry is one of high energy consumption industries. In order to mill steel bar into steel rod, the steel bar is heated to 1,100 - 1,250 ? C. The objective of this work is to investigate energy utilization in reheating furnace using regenerative burners combined with recuperator. The furnace capacity is 30 tonne per hour, pusher type and the natural gas is used as fuel. Billet sizes 120 x 120 x 4000 mm are used for reheating. Waste heat recovery in recuperator system can preheat combustion air to 300 ? C due to material temperature limitations. In order that preheating combustion air temperature near furnace temperature so regenerative burner system provides for substituting that it can preheat combustion air up to 1000 ? C. The results from measurements and energy balance analysis indicate that the regenerative burners combined with recuperator system consume energy approximately 43% less than the case study of conventional recuperative system. |
