Case Study – EfW Bag House Hoppers Installation

Two newly fabricated bag house hopers to be
installed at an energy from waste plant in West
Yorkshire required protection. In service the
hoppers will be exposed to hot ash and gases
at temperatures up to 1400C as they collect
and funnel waste from the plants bag house.
The hoppers were delivered to Corroserve’s
Leeds workshop and were abrasive blasted to
Sa2½ to achieve the required cleanliness
standard. Both units were then thoroughly
cleaned down to remove all dust and debris.
As the hoppers would be exposed to a highly
corrosive waste stream at elevated
temperature Corroserve recommended
coating the internals with Corrothane XT. This
coating is ideal for use on both steel and
concrete surfaces, where good chemical and
high temperature resistance are required,
either for immersed or non-immersed service.
Following cure, DFT and spark testing was
completed to ensure the quality of the coating.
The application of Corrothane XT specialist
protective coating will significantly increa
