PC: GET RESULTS: Fuel: Primary Fuel Diagram

The Primary Fuel Diagram (Fuel Diagram for ICGG plants) screen displays fuel composition and flow rate information. PC plants support blends of coal, biomass and waste coal. IGCC plants only support coal. The following information is shown:

•Area 1 (upper left):

•Fuel Type: (only shown for PC plants) This is the type of fuel being used.

•Name: (only shown for PC plants) This is the name of the fuel being used.

•Fuel-type-specific category: If a fuel blend is being used (PC plants only), this will only be shown if all of the fuels in the blend have the same type. IGCC plants only support coal, and will always show the coal rank here.

•Rank: (coal) The rank of a coal refers to the degree of coalification endured by the organic matter. It is estimated by measuring the moisture content, specific energy, reflectance of vitrinite or volatile matter (these are known as rank parameters). For fuel blends (PC only), this is a composite coal rank of the blend.

•Category: (biomass, PC only) One of the following:

•Energy Crop: This is a crop grown solely for the purpose of energy production.

•Agricultural Residue: This is the portion of a crop grown for other purposes that remains after processing.

•Forestry Residue: This is the residue remaining after a logging operation, e.g. small trees, branches, bark, sawdust, etc.

•Other: This will be shown if all of the components of a blend are biomass, but they are not all in the same category.

•Mining Approach: (waste coal, PC only) One of the following:

•Underground: This refers to coal which is more than 200 feet underground.

•Surface: This refers to coal which is less than 200 feet underground.

•Other: This will be shown if all the components of a blend are waste coal, but they do not all have the same mining approach.

•Area 2 (lower left):

•Fuel Flow Rate: Fuel flow rate into the boiler on a wet basis. Waste products removed prior to the burners are not considered here.

• Our standard coal / biomass / waste coal properties are also included here.

•Area 3 (right):

•Trace Element Flows: (only shown for PC plants) Trace elements are supported in the IECM. The mass flow rate is reported in units of weight per unit of time. All values reflect the elemental mass flow rate.

•Mercury: This is the elemental mercury flow rate in the primary fuel.
