Oil Ash


United Conveyor Corporation designs and supplies pneumatic conveyor systems that reliably transport oil ash from the collection hoppers to the storage silo.

Oil burning boilers produce a light weight, high carbon soot which precipitates to the pneumatic fly ash collection hoppers.  This oil ash is free-flowing when hot but sticky when cool.

Heat tracing and insulating the collection hoppers and conveyor piping keeps the ash hot.  A continuously operating pneumatic conveyor using heated conveyor air keeps the ash moving and prevents build-up.  The storage bin must also be heat traced and insulated.

The crucial element in conveying oil ash is to maintain the ash temperature so it remains free-flowing and to continuously move the ash from the hoppers to the storage bin.
