Where:
E30D = 30 kiln operating day average emission rate of NOX or SO2, lb/ton of clinker.
Ci = Concentration of NOX or SO2 for hour i, ppm.
Qi = Volumetric flow rate of effluent gas for hour i, where
Ci and Qi are on the same basis (either wet or dry), scf/hr.
P = 30 days of clinker production during the same time period as the NOX or SO2 emissions measured, tons.
k = Conversion factor, 1.194 * 10-7 for NOX and 1.660 * 10-7 for SO2, lb/scf/ppm.
n = Number of kiln operating hours over 30 kiln operating days.
