    锅炉是我们日常生活中不可缺少的物品。虽然我们不常见到它,但它与我们的关系息息相关。寒冷的冬天,我们的供暖离不开它。锅炉最常见的问题是结焦,那么你知道锅炉结焦的原因是什么吗?
    Boiler is an indispensable item in our daily life. Although we are not familiar with it, but it is closely related to our relationship. In the cold winter, we can't do without it. The most common problem of boiler is coke, then you know what is the reason of slagging?
    1,结垢的主要原因是锅炉灰的燃烧不完全。锅炉灰的熔点越高,则越不容易结焦,反之熔点越低越容易结焦。
    1, the main reason is the burning of the boiler ash is not complete. The boiler ash melting point is high, is not easy to agglomerate, and the low melting point more easy coking.
    2,空气的影响。在燃烧过程中,由于锅炉内供风不足或燃料与空气混合不良,使燃料达不到完全燃烧,未完全燃烧将产生还原性气体,灰的熔点大大降低。
    2, the impact of air. During the combustion process, the fuel can not be completely burned due to the shortage of the wind in the boiler or the mixture of the fuel and the air, and the incomplete combustion will produce the reducing gas, and the melting point of the ash can be greatly reduced.
    3, 运行操作不当,由于燃烧调整不当使炉膛火焰发生偏斜。一、二次风配合不合理,一次风速高,煤粒没有完全燃烧而在高温软化状态粘附在受热面上继续燃烧,而形成恶性循环。
    3, improper operation, due to improper combustion adjustment to the furnace flame deflection. One or two times, the wind is not reasonable, a high wind speed, coal particles are not completely burned in the high temperature and softening state adhesion on the heated surface continue to burn, and the formation of a vicious circle.
    4,炉膛容积热负荷过大。由于炉膛设计不合理或锅炉不适当的超出力,而造成炉膛容积热负荷过大,炉膛温度过高,造成结焦。
    4, the furnace volume heat load is too large. Due to the furnace design unreasonable or boiler inappropriate excess output, resulting in volume heat load of furnace, the furnace temperature is too high, resulting in coking.
    此外,锅炉结焦的还一个重要原因是由于吹灰、除焦不及时,当炉膛受热面积灰过多,清理不及时或发现结焦后没及时清除,都会造成受热面壁温升高,使受热面严重结焦。所以要经常清理锅炉内的结焦。
    In addition, coking of boiler is one of the important reasons is due to soot blowing, decoking is not timely, when the boiler heating surface fouling too much, cleaning is not timely or found coking did not promptly remove, will cause the heated wall surface, so that the heating surface of serious slagging. So we should always clean up the coking in the boiler.
