Tube material loss, leading to tube failure, due to corrosion and/or erosion is one of the leading causes of forced maintenance outages in the coal and biomass fueled power generation industry. In addition to increasing the required funds for operations and maintenance of the facilities, modifications made to the equipment for emissions reduction compliance have, in many cases, increased the rate of tube material loss. Accordingly, there has been demand for advancements in innovative and cost effective materials technology to mitigate the loss of tube material and thus reduce the frequency of unscheduled and non-routine maintenance events. The employment of High Temperature Ceramic Coating Technology in the power generation industry has proven to be an effective means of protecting the underlying boiler tube material from erosive and corrosive material losses and has afforded additional benefits related to increased heat transfer, increased efficiency, reduced air and flue flow energy consumption and reduced fuel consumption through the reduction of slag and deposits adhering to the coated heat transfer surfaces.
