PC: GET RESULTS: TSP Control: Cold-Side ESP Diagram

Each result is described briefly below:

•Area 1: Flue Gas Entering ESP:

•Temperature In: Temperature of the flue gas entering the ESP. This is determined by the flue gas outlet temperature of the module upstream of the ESP (e.g., the air preheater).

•Flue Gas In: Volumetric flow rate of the flue gas entering the ESP, based on the flue gas inlet temperature and atmospheric pressure.

•Fly Ash In: Total solids mass flow rate in the flue gas entering the ESP. This is determined by the solids exiting the module upstream of the ESP (e.g., the air preheater).

•Mercury In: Total mass of mercury entering the ESP. The value is a sum of all the forms of mercury (elemental, oxidized, and particulate).

•Area 2: Flue Gas Exiting ESP:

•Temperature Out: Temperature of the flue gas exiting the ESP. The model currently does not alter this temperature through the cold-side ESP.

•Flue Gas Out: Volumetric flow rate of the flue gas exiting the ESP, based on the flue gas exit temperature and atmospheric pressure.

•Fly Ash Out: Total solids mass flow rate in the flue gas exiting the ESP. This is a function of the ash content of the inlet flue gas and the particulate removal efficiency performance parameter.

•Mercury Out: Total mass of mercury exiting the ESP. The value is a sum of all the forms of mercury (elemental, oxidized, and particulate).

•Area 3: ESP Performance:

•Ash Removal: Ash removal efficiency of the ESP. This is a function of the particulate emission constraint and the inlet ash mass flow rate.

•SO3 Removal: Percent of SO3 in the flue gas removed from the ESP. The SO3 is assumed to combine with H2O and leave with the ash solids as a sulfate (in the form of H2SO4).

•Mercury Removal: Percent of the total mercury removed from the ESP. The value reflects a weighted average based on the particular species of mercury present (elemental, oxidized, and particulate).

•Area 4: Collected Fly Ash:

•4a: Dry Ash: Total mass flow rate of the solids removed from the ESP. This is a function of the solids content in the flue gas and the particulate removal efficiency performance parameter . The value is given on a dry basis.

•4b: Sluice Water: Water added to the dry fly ash. This water is added for transportation purposes.

•4a: Wet Ash: Total mass flow rate of the solids removed for waste management. This includes dry fly ash and sluice water. The value is given on a wet basis.
