Some screens deal with the composition of ash in coal, biomass or waste coal. The ash properties are:

•SiO2: The percent by weight of silicon dioxide in the ash.

•Al2O3: The percent by weight of aluminum oxide in the ash.

•Fe2O3: The percent by weight of ferric oxide in the ash.

•CaO: The percent by weight of calcium oxide in the ash.

•MgO: The percent by weight of magnesium oxide in the ash.

•Na2O: The percent by weight of sodium oxide in the ash.

•K2O: The percent by weight of potassium oxide in the ash.

•TiO2: The percent by weight of titanium dioxide in the ash.

•MnO2: The percent by weight of manganese dioxide in the ash.

•P2O5: The percent by weight of phosphorus pentoxide in the ash.

•SO3: The percent by weight of sulfur trioxide in the ash.

These screens may also include the following:

•Total %: This shows the total of the percentages listed above; they should add up to 100%. This is typically the last line shown on screens that include it.
