Mass In/Out

This screen displays the flow rates of fuels and chemicals into the plant, and solid and liquid flow rates out of the plant. This information is displayed in two tables: Chemical Inputs and Solid & Liquid Outputs. The details vary slightly between plant types, as indicated below, but the information shown is very similar.

The following plant inputs (Chemical Inputs) are displayed in the table on the left:

•Coal: (if applicable) Flow rate of coal used in the power plant.

•Oil: (if applicable) Flow rate of oil used in the power plant.

•Natural Gas: (if applicable) Flow rate of natural gas used in the power plant.

•Petroleum Coke: (NGCC and IGCC Only) Total mass of petroleum coke used in the power plant.

•Other Fuels: (NGCC and IGCC Only) Flow rate of other fuels used in the power plant.

•Total Fuels: This is the flow rate of fuel entering the power plant. This result is highlighted in yellow.

•Lime/Limestone: Total mass of this reagent used in the power plant on a wet basis.

•Sorbent: Total mass of sorbent used in the power plant.

•Ammonia: Total mass of ammonia used in the power plant.

•Urea: (PC Only) Total mass of urea used in the power plant. Urea is the reagent used to reduce NOx in the SNCR technology.

•Dibasic Acid: (PC Only) Total mass of dibasic acid used in the power plant.

•Activated Carbon: Flow rate of activated carbon injected in the power plant.

•Other Chemicals, Solvents & Catalyst: (NGCC and IGCC Only) Flow rate of other chemicals, solvents and catalysts used in the power plant.

•Total Chemicals: Flow rate of reagent entering the power plant. This result is highlighted in yellow.

•Oxidant: (IGCC Only) Flow rate of oxidant entering the power plant. This includes oxygen, nitrogen and argon.

•Process Water: (NGCC and IGCC Only) Flow rate of water used in the power plant.

The following plant outputs (Solid & Liquid Outputs) are displayed in the table on the right:

•Bottom Ash Disposed: (PC Only) Total mass of bottom ash collected in the power plant on a dry basis.

•Slag: (NGCC and IGCC Only) Flow rate of slag from the power plant on a dry basis.

•Fly Ash Disposed: (PC Only) Total mass of fly ash collected in the power plant on a dry basis.

•Ash Disposed: (NGCC and IGCC Only) Flow rate of ash from the power plant on a dry basis.

•Scrubber Solids Disposed: (PC and NGCC Only) Total mass of scrubber solid wastes collected in the power plant on a dry basis.

•Other Solids Disposed: (IGCC Only) Flow rate of scrubber and other treatment solid wastes from the power plant on a dry basis.

•Particulate Emissions to Air: Flow rate of particulates emitted to the air from the plant.

•Captured CO2: Flow rate of the captured CO2.

•Byproduct Ash Sold: Flow rate of ash (bottom and fly ash) sold in commerce as a by- product on a dry basis.

•Byproduct Gypsum Sold: Flow rate of flue gas treatment solids sold in commerce as a by- product on a dry basis.

•Byproduct Sulfur Sold: Flow rate of elemental sulfur recovered from flue gas and sold in commerce as a by-product on a dry basis.

•Byproduct Sulfuric Acid Sold: Total mass of sulfuric acid recovered from the flue gas and sold in commerce as a by-product.

•Total: This is the total wet solid mass exiting the power plant. This result is highlighted in yellow.

•Water Evaporated (Consumptive): This is the amount of water lost due to evaporation.

•Cooling Water Discharge: (Once-Through Cooling Only) This is the total cooling water required.
