Residue mainly from the coal burning process that falls to the bottom of the boiler for removal and disposal.
(also, clinker): the residue from an incinerator that falls through the grate mechanism at the bottom of the furnace.
Noncombustable ash that is left after solid fuel has been burned.
An inert ash produced from the treatment of MSW
Incombustible matter resulting from combustion that does not leave as fly ash.
relatively coarse, noncombustible, generally toxic residue of incin-eration that accumulates on the grate of a furnace.
The unburnable ash residue remaining in an incinerator or energy recovery facility after the burnables have been incinerated.
the residual ash fraction arising from waste combustion, recovered from the bottom of the furnace of incinerators and other combustion plant.
The non-airborne combustion residue from incinerating solid waste.
A part of coal that doesnâ€™t burn, but instead falls to the bottom of the boiler. It consists mostly of oxides of silicon, aluminum and iron.
Slag or other residue remaining in the boiler after coal is burned.
unburned or partially burned material that falls through, or is discharged from, the burning grate of an incinerator.
The non-airborne combustion residue from burning pulverized coal in a boiler; the material which falls to the bottom of the boiler and is removed mechanically; a concentration of non-combustible materials, which may include toxics.
Ash that collects under the grates of a combustion furnace.
Heavier ash that collects in the bottom of the boiler after coal is burned. This ash is collected and stockpiled in approved disposal areas.
"Bottom ash" refers to the non combustible constituents of coal with traces of combustibles embedded in forming clinkers and sticking to hot side walls of furnace during the furnace working. The clinkers fall by themselves into the water or sometimes by poking manually, and get cooled.
