近几年来,随着燃油锅炉逐渐改为燃煤锅炉,以及一些新扩建的燃煤锅炉增加,对于吹灰器的需要已渐趋迫切。这非但对电业方面如此,即使其他一些工业(如造纸或化工),为了锅炉受热面的清洁,也需要加装吹灰器。众所周知,经常使用有效果的吹灰器吹扫锅炉水冷壁管,可以吹掉灰渣,避免炉膛结灰或结渣,这对于改善和保持炉膛辐射受热面的传热效率,提高锅炉经济性是有好处的。合理吹灰,能保持辐射受热面的清洁,这对于燃用多灰份和熔点较高的煤种时尤为需要。
In recent years, the need for sootblowers has become increasingly urgent with the gradual conversion of oil-fired boilers to coal-fired boilers and the expansion of some newly expanded coal-fired boilers. This is not only true of the electrical industry, but even some other industries (such as paper or chemical) require the installation of sootblowers for the heating of boilers. As we all know, often the use of effective sootblowers sweeping the boiler water wall tube, you can blow off the ash to prevent the furnace ash or slagging, which is to improve and maintain the furnace radiant heating surface heat transfer efficiency and improve the boiler economy beneficial. Reasonable soot blowing, can keep the radiation heating surface clean, which for burning with more ash and coal with higher melting point is particularly needed.
