西德于六十年代研制了水吹灰器来清除褐煤炉的结渣,取得了良好的效果,随后在澳大利亚的褐煤炉上采用,也获成功。六十年代后期美国亦开始在燃褐煤和次烟煤的锅炉上使用水吹灰器。这些国家都有专业厂制造水吹灰器,成为随褐煤炉供货的基本装备。苏联先是在烧油页岩的锅炉上,近年内也在褐煤炉上试用了水吹灰器。目前比较一致的看法是认为水吹灰器比之蒸汽或压缩空气吹灰器对于清除褐煤炉水冷壁上的结渣具有更优越的性能和显著的效果。
West Germany in the sixties developed a water sootblower to remove lignite slag slagging, and achieved good results, followed by the lignite furnace in Australia, also succeeded. In the late 1960s, the United States also started to use water sootblowers on lignite-fired and sub-bituminous boilers. These countries have a professional factory manufacturing water sootblowers, with the lye furnace supply of basic equipment. The Soviet Union first boiled oil shale boiler, in recent years, also tried on the lignite furnace water soot blower. The current consensus is that the water sootblower is superior to the steam or compressed air sootblower in removing excess slagging on the water wall of a brown coal furnace.
