Allen-Sherman-Hoff material handling for power and process industries

Solutions for bottom ash, fly ash, and other material conveyance.

Our extensive knowledge of the physical and chemical properties of different ash and bulk material combinations has made us a trusted partner for tailored ash and material handling solutions. We serve a wide range of industries including power generation, renewable energy, waste-to-energy, pulp & paper, and other solid-fuel applications.

Bottom ash from the combustion of solid fuels

In addition to providing operational and environmental benefits, Allen-Sherman-Hoff bottom ash handling systems  are a reliable and cost-effective alternative to ash storage ponds. Our bottom ash systems are available in either wet or dry types.

Fly ash from economizer/air heater hoppers and particulate collection systems

Allen-Sherman-Hoff fly ash handling systems  are a reliable, low maintenance, cost-effective means of conveying and collecting fly ash from a boiler and its emissions control systems. Four basic types of pneumatic transport systems and related components are available depending on your specific application.

Replacement parts and performance upgrades

We provide high-performance parts and upgrades for our Allen-Sherman-Hoff line of ash handling equipment , as well as most other brands. Inventory is maintained for a wide range of critical parts, including bottom ash components, fly ash components, and piping and fittings. This means fast delivery of the parts you need most.

Fuel conveyors and delivery systems

The reliable, safe and uninterrupted supply of fuel for boilers is essential to power generation. We provide a range of solid fuel conveyance and in-feed technologies to transport and process fuel for power, heat and process steam generation. Fuels include coal, biomass, and waste fuels including MSW and RDF.

Reagent and byproduct handling

Allen-Sherman-Hoff material conveying systems can support the transport, injection, processing and storage of reagents and byproducts of environmental systems, including limestone, lime, sodium, or other sorbents, as well as gypsum byproduct from the wet scrubbing process.
