Ash Properties

← Previous | Next →

The Ash Properties parameter screen allows you to specify the ash properties of the fuel specified on Fuel Properties screen. These properties are only editable for individual fuels.

This screen displays the oxide content of the ash in fuel on a percent of total ash basis. The ash content is used to determine the resistivity of the ash. This, in turn, determines the specific collection area (SCA) of the cold-side ESP. See our standard list of Ash Properties for details on the values that can be edited here.

There are two additional values displayed, highlighted in yellow, beneath the ash properties referenced above:

•Other: If the percentages above add up to less than 100%, it is assumed that the ash includes some other component(s) that are not listed. This is the percentage of other component(s) required to bring the total up to 100%.

•Total: This is the total percentage of all components. It should always be 100%.

Warning:

Uncertainty on this screen should only be used for Batch Processing. Varying the components independently does not make sense - if one percentage is higher, another percentage will need to be lower to keep the total at 100%.
