以往点火炉燃料用的混合煤气消耗量约为19400千卡,以水岛4号烧结机为例,年消耗热量达59×10~9千卡,相当于3亿日元。为此对现有点火炉的燃烧情况进行了调查,以期找出节能的对策。经测定,当时使用的点火炉内温度并不均匀,在1100～1270℃之间波动,且尚有部分点火用混合煤气没有充分燃烧,局部未燃CO 浓度达7%。其原因是原来使用的套筒型点火烧嘴结构不大合理,造成助燃空气与煤气混合不够,致使沿台车宽度方向上烧结料的着火时间出现参错,因而也造成了烧结矿燃料单耗的增加。针对上述存在问题,提出了新颖的长条
In the past, furnace gas used for fuel gas consumption was about 19,400 kcal. Taking Shui Dao 4 Sintering Machine as an example, the annual consumption of heat was 59 × 10 ~ 9 kcal, equivalent to 300 million yen. To this end the existing ignition stoves were investigated for combustion, with a view to find energy-saving measures. It was determined that the temperature in the furnace used at that time was not uniform and fluctuated between 1,100 and 1,270 ° C, and some of the ignition mixed gas still did not burn sufficiently and the local unburned CO concentration reached 7%. The reason is that the sleeve-type ignition burner originally used is not reasonable in structure, resulting in insufficient mixture of combustion air and gas, resulting in a fault in the ignition time of the sintering material along the width direction of the trolley, thus resulting in the consumption of sinter fuel Increase. In response to the above problems, proposed a new bar
