The technology allows to receive ashes with coal content of 25-30% from ashes with coal content of 4-6%, using inter-circuitation dust-separators and small-sized dusters.

Use of the closed separating and catching allows avoiding dust emission (blowouts) in an atmosphere without large-sized sleeve filters. The process proceeds without water application. The allocated coal can be used for the subsequent incineration. The cleared ashes (with coal content of 4-6%) can be used as a substitute of cement (up to 50% on weight) in quality low-water-containing cementing materials

The set-up is made "on a turn-key basis" and has a productivity up to 200 000 ? of ash per year.
