Wear damage caused by fly ash erosion is an extremely common damage mechanism in tubular air heaters and air to air heat exchangers. Fine particulates in gas streams cause both tubes and tubesheet plates to thin and fail over time.
Factors that influence erosion patterns:
These factors commonly result in localized patterns of wear damage which, if left unchecked, can have a major impact on equipment performance.
CMS has developed a number of field perfected solutions that can provide short term relief to address erosion wear damage in tubular air heaters and air to air heat exchangers. One of our most popular solutions to address this problem, is to pro-actively install CMS heat treated hardened sleeves at the gas inlet of areas vulnerable to wear damage.
Other short-term CMS solutions for this problem include:
CMS has developed new technology for long term relief from fly ash erosion damage in tubular air heaters and air to air heat exchangers. The CMS Erosion Resistant Optimal Solution or EROS is a patent pending design that eliminates the root cause of this damage mechanism.
