Introduction
Ash content is an important parameter for fuel deliveries since ash is a by-product of combustion and
ends up as bottom ash or fly-ash and needs to be removed. Depending on the jurisdiction, ash may be
deposited or used for production of other products or as fertilizer. Knowing how much ash comes with a
fuel can have economic consequences. Since the chemical composition of ash contributes to slagging and
corrosion in the combustion equipment, it is therefore important to know the amount of ash contained
in a fuel. Other testing standards are used for determining the chemical composition of ash.
