Fuel Properties

← Previous | Next →

Some screens deal with the fuel properties, including the ultimate analysis of coal, biomass, or waste coal. The following properties are included:

•Heating Value: Higher heating value (HHV) is the thermal energy produced in Btu/lb of fuel (wet) from completely burning the fuel to produce carbon dioxide and liquid water. The latent heat of condensation is included in the value.

•Carbon: The weight percent of carbon in the fuel on an elemental (C) and wet basis.

•Hydrogen: This is the weight percent of hydrogen in the fuel on an elemental (H) and wet basis.

•Oxygen: This is the weight percent of oxygen in the fuel on an elemental (O) and wet basis.

•Chlorine: This is the weight percent of chlorine in the fuel on an elemental (Cl) and wet basis.

•Sulfur: This is the weight percent of sulfur in the fuel on an elemental (S) and wet basis.

•Nitrogen: This is the weight percent of nitrogen in the fuel on an elemental (N) and wet basis.

•Ash: This is the weight percent of ash in the fuel on a wet basis.

•Moisture: This is the weight percent of moisture in the fuel on a wet basis.

These screens may also include the following at the top of the screen:

•Errors and/or Warnings: If a fuel blend in a Pulverized Coal (PC) plant is configured in a way that violates our recommendations, there will be a note highlighted in yellow referring the user to a warning on the Config screen. If the issue is serious enough to prevent the model from running correctly, there will be a note highlighted in yellow referring the user to an error on the Config screen. An error here will also trigger an error screen in the GET RESULTS Program Area.

•Percentage of this fuel in the blend: Pulverized Coal (PC) plants support fuel blends; this is the percentage of the fuel described on this screen in the blend.

•Fuel Type: Pulverized Coal (PC) plants support biomass and waste coal in addition to coal; this line indicates which fuel type is being used.

•Coal Rank (coal), Category (biomass) or Mining Approach (waste coal).

•Name: The name of the fuel.

The following may be included at the bottom of the screen.

•Total %: This shows the total of the percentages listed above; they should add up to 100%. This line may be highlighted in yellow.

•Cost or Default Cost: This is the as-received cost of the fuel.
