Vacuum solutions engineered for coal & power generation

The oldest combustible dust in the record still runs the most vertical geography in industry — coal climbs from unloading pit to bunker floor through galleries, towers and tripper decks, shedding fines at every elevation. The housekeeping program follows it floor by floor.

Coal & Power Generation production process explorer

Every stage. Every challenge. The right vacuum solution.

Coal's path through a plant is vertical — every lift and transfer sheds fines onto the floor below. Walk the stages to see where dust generates and where the recovery program earns its keep.

Stage 01 — Rail & truck unloading

Rotary dumpers and receiving hoppers make the first cloud of the day — pit floors and surrounds join the scheduled rotation with tools sized for spillage plus fines.

Key challenges

The oldest dust in the record, still writing entries

  • The Oldest Record

    Coal dust's explosibility has been documented since the 1840s mine investigations — the record predates every other dust standard.

  • Volatile-Driven Reactivity

    Reactivity rises with volatile content — bituminous and sub-bituminous fines govern the equipment specification.

  • Two Jurisdictions

    Mines run under MSHA with rock-dusting rules; surface plants answer to OSHA and the NFPA framework, now consolidated in NFPA 660.

  • Elevated Inventory

    Tripper decks and transfer towers layer fines high above ignition-rich equipment, out of daily sight.

  • Self-Heating Coal

    Stockpiles and bunkers smolder from within — smoldering material near any equipment is the forbidden event.

  • Ash-Side Exposure

    Trace constituents, including mercury, put exposure control on the ash-side housekeeping program.
