Fly Ash Drying

As a result of industry trends, public scrutiny, government regulation, water constraints, etc., coal power plants domestically and internationally are striving to eliminate their ash ponds and replace them with dry solutions. For those considering a transition from wet to dry ash handling, Vulcan® Drying Systems can help.

Benefits of Vulcan Fly Ash Dryers

Vulcan® Drying Systems' Fly Ash Dryers are custom-designed and manufactured around the desired solids tonnage and the moisture content of the customer's individual project. Our technical team considers all the parameters: available space, budget, current and future fuel use, storage capacity, location, generation rate, routing, and aftermarket choices, such as marketing and resale.

Typically, drying systems include a rotary dryer consisting of a drum with a burner. Fly ash is fed into the rotary dryer, then discharged to a transfer conveyor for sorting and separation. The vapor from the process is pulled through a cyclone to eliminate fine dust; a high-temperature, high-yield baghouse removes fine particulates from the vapor stream.

The resulting dry fly ash is easier to store and transport, and road construction and concrete industries have increased the demand for this material. The sale of fly ash for concrete production is potentially an excellent ancillary profit source for your plant.
