引起热风炉偏运行的原因有哪些?

  使用热风炉时有时会遇到此类问题,我们需要及时检查和解决。 部分操作是故障现象之一。 具体而言,这意味着炉中的氧化物层在燃烧时燃烧。 部分操作会严重影响气体质量。 由于设备无法正常工作,因此让我们分析部分操作的原因。
  When using the hot blast stove, we sometimes encounter such problems. We need to check and solve them in time. Partial operation is one of the fault phenomena. In particular, this means that the oxide layer in the furnace burns during combustion. Some operations will seriously affect the gas quality. Because the device is not working properly, let's analyze the reasons for some operations.
  1.水套引起的泄漏:气化用煤的质量应良好。 ,粘度小,第二,挥发物小,第三,块直径不大于40mm,第四,煤块强度中等。 如果使用高内聚力的煤,将导致炉中的干馏层形成糊状物并形成大的炉渣,这将严重影响产气。 在严重的情况下,会损坏设备。 在运营管理中,煤炭质量非常重要。 其中一些会导致炉底部分爆炸和部分燃烧。
  1. Leakage caused by water jacket: the quality of coal for gasification shall be good. First, the viscosity is small, second, the volatile matter is small, third, the block diameter is not more than 40 mm, fourth, the coal block strength is medium. If high cohesion coal is used, it will lead to the formation of paste and large slag in the retort, which will seriously affect the gas production. In severe cases, damage to the equipment can occur. In operation management, coal quality is very important. Some of them will cause partial explosion and partial combustion at the bottom of the furnace.
  2.空气量不均匀:空气进入熔炉并进入熔炉。 由于在安装过程中炉子距中心线15厘米,因此空气从炉膛孔中流出,并且处于偏置状态。 一方面,风量大,而风量小。 如果炉子长时间不旋转,则风量大而风量小。 火势不佳也会引起局部灼伤。
  2. Uneven air volume: air enters the furnace and enters the furnace. Since the furnace is 15cm away from the center line during installation, the air flows out of the furnace hole and is in the offset state. On the one hand, the air volume is large, while the air volume is small. If the furnace does not rotate for a long time, the air volume is large and small. Poor fire can also cause local burns.
  3,由炉内局部炉渣引起:由于运行,炉渣是由火产生的,不能及时处理。 当去除灰烬时,灰烬被顺利排出,并且炉渣没有撒粉,导致灰烬层太厚。 灰层的通风阻力小于煤层的通风阻力,从而导致过多的空气量,氧化层繁荣,氧化层向上移动,并且灰层越来越高。 在煤灰的下部,由于煤层的大风阻,风量小,反应缓慢,并且煤灰层越来越薄,导致严重的局部燃烧。
  3, caused by local slag in the furnace: due to operation, slag is generated by fire and cannot be treated in time. When the ash is removed, the ash is discharged smoothly, and the slag is not powdered, resulting in too thick ash layer. The ventilation resistance of the ash layer is less than that of the coal seam, which leads to excessive air volume, prosperity of the oxide layer, upward movement of the oxide layer, and higher and higher ash layer. In the lower part of the coal ash, due to the large wind resistance of the coal seam, the air volume is small, the reaction is slow, and the coal ash layer is thinner and thinner, leading to serious local combustion.

  4.产煤不均匀:在进入热风炉的煤中,松煤锥的位置设计不合理,或者调整不当,导致一侧的煤更多,一侧的煤更少,更多。 小零件鼓出。 较少的零件形成凹坑。 小山的抗风性大,坑外的抗风性小,抗风性小,抗风性强的一侧着火,引起局部燃烧。
  4. Uneven coal production: in the coal entering the hot blast furnace, the position design of the loose coal cone is unreasonable, or the adjustment is improper, resulting in more coal on one side, less and more coal on one side. Small parts are bulging out. Fewer parts form pits. The wind resistance of the hill is large, the wind resistance outside the pit is small, the wind resistance is small, and the side with strong wind resistance catches fire, causing local combustion.
  5,由原始炉造成的状况:所谓的原始炉产生的状况,即在点火之前,炉内未均匀地装载炉渣,它急于燃煤,导致一侧着火,而不能上火 火。 炉渣的下部通风良好,炉渣一侧的炉渣较高。
  5. Conditions caused by the original furnace: the so-called conditions generated by the original furnace, that is, before ignition, the furnace is not evenly loaded with slag, it is eager to burn coal, causing one side to catch fire, rather than catch fire. The lower part of slag is well ventilated, and the slag on one side of slag is higher.
  上述五个原因是热风炉部分运行的主要原因。 如果在实际操作中遇到部分操作,则应及时检查炉子的燃烧情况,找出问题的原因,有针对性地解决。 这可能是减少问题的好方法。
  The above five reasons are the main reasons for the partial operation of the hot blast furnace. If part of the operation is encountered in the actual operation, the combustion of the furnace shall be checked in time to find out the cause of the problem and solve it pertinently. This may be a good way to reduce problems.
