在锅炉装置中腐蚀是主要问题,特别是燃烧或焚化废燃料的锅炉。 腐蚀有两种基本类型:一种由于高温引起的腐蚀;而另一种是由于低温引起的腐蚀——经常称为冷端腐蚀。例如过热器和省煤器或空气预热器部件尤其受这些因素的影响,因为这些部件都是在烟气温度范围的高温端和低温端运行。另外,锅炉护板、管道系统和烟囱也受影响,因为它们触及腐蚀性烟气。 Corrosion is a major problem in boiler installations, especially boilers burning or incinerating spent fuel. There are two basic types of corrosion: one is due to corrosion at high temperatures and the other is corrosion at low temperatures - often referred to as cold end corrosion. For example, superheater and economizer or air preheater components are particularly affected by these factors, as these components operate both at the high and low temperature end of the flue gas temperature range. In addition, boiler shields, piping and chimneys are also affected as they touch corrosive fumes.
