我国钢铁工业能源利用效率很低,据冶金部统计,大多数加热炉的平均效率只有30%左右。为了节约能源,降低燃耗,必须提高工业炉窑的热效率,大力发展节能型炉窑。一、更新烧嘴经过普查,西南地区工业炉窑所用的燃烧器,种类繁多,绝大多数是50年代以前的燃烧器,应当尽快地把这批落后的燃烧器更换下来,使用性能好的先进燃烧器。现已研制成功使用天然气的平焰燃烧器系列,其能力由10米~3/时到200米~3/时共9个型号,可以推广使用,有良好的节能效果。平焰燃烧器的性能:火盘直径
China’s steel industry, energy efficiency is very low, according to the metallurgical statistics, the average efficiency of most furnaces only about 30%. In order to save energy and reduce fuel consumption, we must improve the thermal efficiency of industrial furnaces and vigorously develop energy-saving furnaces. First, to update the burner After the census, Southwest Industrial Furnace burner used, a wide range, the vast majority of the burner before the 1950s, should be replaced as soon as possible behind the burner, the use of advanced performance and good performance burner. Has been successfully developed the use of natural gas flat flame burner series, its capacity from 10 m ~ 3 / h to 200 m ~ 3 / h total of 9 models, can promote the use of a good energy-saving effect. Flat flame burner performance: the diameter of the fire
