目前清除锅炉空气预热器积灰的方法有多种,但都存在较大的弊病,不是热损耗过高,就是必须停炉才能进行,或是清灰效果很差。而本文所介绍的钢管式空气预热器清灰方式,不仅能十分有效地清除附着在钢管内壁的粘结性积灰,而且对锅炉本身无任何热能损耗,并且是在锅炉正常运行状态下清灰,清灰成本非常低廉。实践证明,它是目前一种成功的锅炉尾部受热面清灰技术。 At present, there are many ways to remove fouling of the air preheater of the boiler, but all have larger disadvantages, either that the heat loss is too high, that the ovens must be stopped, or that the cleaning effect is very poor. The steel tube air preheater cleaning method introduced in this paper not only can remove the cementitious fouling adhering to the inner wall of the steel pipe very effectively, but also has no heat loss to the boiler itself, and it is under the condition of normal operation of the boiler Ash, cleaning costs very low. Practice has proved that it is currently a successful boiler tail heating surface cleaning technology.
