尽管、曾热心地建议在投入运行前,将高压锅炉的蒸发部分进行清洗,但是,没有建议将过热器和再热器进行清洗。需要洗掉形成积垢的物质,首先是因为它们常常在水冷壁管内引起腐蚀。我们知道,在过热器和再热器内,都没有发生过因原有的压制铁鳞存在而引起的事故。薄的压制铁鳞通常都粘结在管壁上,并且不容易被干的蒸汽冲刷掉。松散的氧化物和在大气中生成的铁锈,通常可用“蒸汽吹洗”法很容易地加以清除。 Although it has been enthusiastically recommended that the evaporation section of the high-pressure boiler be cleaned before commissioning, the superheater and reheater are not recommended for cleaning. The fouling substances need to be washed away, first of all because they often cause corrosion in the waterwall tubes. We know that in the superheater and reheater, have not occurred due to the existence of the original suppression of iron scales caused the accident. Thin pressed iron scales are usually bonded to the pipe wall and are not easily washed away by dry steam. Loose oxides and rust generated in the atmosphere can often be easily removed by the “steam purge” method.
