Boiler slagging occurs when hot, molten or semi-molten ash particles strike and adhere to furnace surfaces in the radiant section of the boiler. Fouling occurs in the lower temperature convective sections of the boiler when volatile constituents in the ash such as the alkali oxides condense and collect further ash which then sinters into a hard mass.
