According to the curve of rolled coil annealing temperature, the curve of gas and air consumption, the air volume for one batch annealing furnace and discharge fluegassystem are obtained.
Fluegas can also beset up waste heat recovery system to increase the thermal efficiency of furnace.
也可以设置烟气余热回收系统来提高加热炉的热效率。

The non-oxidizing zone is consisted of entry sealed room, waste gas preheating zone, direct heating zone, and furnace nozzle and fluegas exhausting system.
