Electrostatic Precipitator: Equipment Tab

Variable Definitions, Ranges and Default Values

The following table shows the meaning of the variables appearing in this tab, as well as their default values and their generally acceptable range. Note that due to the manner by which the variables are used by the sizing and costing equations, the range of acceptable values may be further reduced.

Variable	Default Value	Range

◙ Plate Length The length of the plates in the ESP	4.0 m	Positive
◙ Plate Height The height of the plates in the ESP	12.0 m	Positive
◙ Max. Plate Length The maximum plate length that the ESP can support	4.0 m	Positive
◙ Max. Plate Height The maximum plate height that the ESP can support	15.0 m	Positive
◙ Plate Separation The distance between two plates	40.0 cm	Positive
◙ Number of Ducts The number of ducts per unit	50	Positive
○ Aspect Ratio The duct Length over plate height ratio	1.3	Positive
○ Number of Sections	4	Positive
◙ Number of Plates The number of plates utilized in the ESP	0	Positive
● Overall Collection Area The total area used for collection of particles	0.00 m²	Positive
● Total Length Number of sections times plate length	16.0 m²	Positive
● Total Width Number of ducts times plate separation	20 m²	Positive
○ Insulated Is the unit insulated?	Yes	Yes/No

Symbol Key: ○ User-specified value (always input); ● Calculated value (always output); ◙ Sometimes input, sometimes output

Sizing

In Design Mode, the use specifies the Max Plate Length and the Max Plate Height and the system computes the Plate Height, Plate Length, Plate Separation and the Number of Ducts.

In Rating mode, the user specifies the plate length, plate height, plate separation, number of ducts, number of plates and the number of units.

For more information, see Electrostatic Precipitation: Modeling Calculations.

Costing

The equipment purchase cost is based on the total collection area. By default it is calculated by the programs built-in model for a ESP.
