Suppliers of Furnace Bottom Ash Furnance Bottom Ash (FBA) is the "coarse" ash fraction produced by coal-fired power stations when pulverised fuel is burned at high temperatures and pressures. It has similar chemical properties to Fly Ash, consisting predominantly of oxides of silica, aluminium and iron, but has a sand-like gritty texture.

Coal Ash

Bottom ash is a heavier, coarse material captured at the bottom of the coal furnace. Bottom ash can contain cresol and semivolatile organic compounds such as polycyclic aromatic hydrocarbons . Bottom ash is unlikely to be in coal ash ponds because it is typically disposed of immediately after combustion and sent to a landfill.

Stabilization and Solidification of Fine Incineration

The fine incineration bottom ash (IBA) is usually landfilled due to its high heavy metal content and low strength. In this study, the fine IBA was stabilized/solidified by a green binder, ground granulated blast-furnace slag (GGBS), as a potential subbase material for road construction, in comparison with the traditional binder, ordinary portland cement (OPC).

Bottom Ash as a Highway Material

Coal ash is produced in two forms: bottom ash and fly ash. Bottom ash is the slag that builds up on the heat-absorbing surfaces of the furnace and subsequently falls through the furnace bottom to the ash hopper below. Because it is col­ lected by gravity, bottom ash is a relatively coarse material.
