摘要： A sootblower for the cleaning of internal surfaces of large scale boilers which are subject to the accumulation of soot or slag encrustations. In instances where a sootblower is used to project the jet of steam of steam or a steam/air mixture, between actuation cycles, condensate can form in the sootblower or the associated piping. At the beginning of an actuation cycle the condensate is ejected from the sootblower. If the condensate impinges against the heat transfer surfaces inside the boiler it can cause damage to these surfaces through excessive thermal and mechanical shock. In accordance with this invention the sootblower is provided with a nozzle block assembly incorporating a condensate separator which causes condensate to be ejected by the lance tube away from impact with the heat transfer surfaces where it can be safely dissipated from the boiler without causing damage to the heat transfer surfaces which are cleaned using a substantially fully vaporous pure spray of sootblowing medium.
摘要翻译： 用于清洁大型锅炉内部表面的吹灰器，这些锅炉容易积聚烟灰或炉渣结垢。 在吹灰器用于将蒸汽或蒸汽/空气混合物的蒸汽喷射在致动循环之间的情况下，在吹灰机或相关联的管道中可形成冷凝物。 在致动循环开始时，冷凝物从吹灰器喷出。 如果冷凝物撞击锅炉内的传热表面，可能会因过热和机械冲击而损坏这些表面。 根据本发明，吹灰器设置有一个包括冷凝物分离器的喷嘴块组件，其使冷凝物被喷枪管排出，远离与传热表面的冲击，在该传热表面上可以从锅炉安全地散发，而不会损坏 使用基本上完全蒸发的吹灰介质的纯喷雾进行清洁的传热表面。
