Section NR 465.03 - Symbols

The symbols used in this subchapter have the following meanings:

(1) "ac" means after the control system is installed and operated.

(2) "Ak" is the area of each natural draft opening k in a total enclosure, in square meters.

(3) "bc" means before control.

(4) "Caj" is the concentration of VHAP in gas stream j exiting the control device, in parts per million by volume.

(5) "Cbi" is the concentration of VHAP in gas stream i entering the control device, in parts per million by volume.

(6) "Cc" is the VHAP content of a finishing material c in kilograms of VHAP per kilogram of coating solids (kg VHAP/kg solids), as supplied. Also given in pounds of VHAP per pound of coating solids (lb VHAP/lb solids).

(7) "Cdi" is the concentration of VHAP in gas stream i entering the control device from the affected source, in parts per million by volume.

(8) "Cfk" is the concentration of VHAP in uncontrolled gas stream k emitted directly to the atmosphere from the affected source, in parts per million by volume.

(9) "E" is the emission limit achieved by an emission point or a set of emission points, in kg VHAP/kg solids (lb VHAP/lb solids).

(10) "F" is the control device efficiency, expressed as a fraction.

(11) "FV" is the average inward face velocity across all natural draft openings in a total enclosure, in meters per hour.

(12) "G" is the VHAP content of a contact adhesive, in kg VHAP/kg solids (lb VHAP/lb solids), as applied.

(13) "Mc" is the mass of solids in finishing material c used monthly, kg solids/month (lb solids/month).

(14) "N" is the capture efficiency, expressed as a fraction.

(15) "Qaj" is the volumetric flow rate of gas stream j exiting the control device, in dry standard cubic meters per hour.

(16) "Qbi" is the volumetric flow rate of gas stream i entering the control device, in dry standard cubic meters per hour.

(17) "Qdi" is the volumetric flow rate of gas stream i entering the control device from the emission point, in dry standard cubic meters per hour.

(18) "Qfk" is the volumetric flow rate of uncontrolled gas stream k emitted directly to the atmosphere from the emission point, in dry standard cubic meters per hour.

(19) "Qin i" is the volumetric flow rate of gas stream i entering the total enclosure through a forced makeup air duct, in standard cubic meters per hour, wet basis.

(20) "Qout j" is the volumetric flow rate of gas stream j exiting the total enclosure through an exhaust duct or hood, in standard cubic meters per hour, wet basis.

(21) "R" is the overall efficiency of the control system, expressed as a percentage.

(22) "S" is the VHAP content of a solvent, expressed as a weight fraction, added to finishing materials.

(23) "W" is the amount of solvent, in kilograms (pounds), added to finishing materials during the monthly averaging period.
