1 The initial and subsequent PM performance tests are performed using Method 5 or 5I and consist of three test runs.
2 If the average temperature at the inlet to the first PM control device (fabric filter or electrostatic precipitator) during the D/F performance test is 400 °F or less, this limit is changed to 0.40 ng/dscm (TEQ).
3 Measured as propane.
4 Any source subject to the 24 ppmvd THC limit may elect to meet an alternative limit of 12 ppmvd for total organic HAP.
Where:
PMalt = Alternative PM emission limit for commingled sources.
0.006 = The PM exhaust concentration (gr/dscf) equivalent to 0.070 lb per ton clinker where clinker cooler and kiln exhaust gas are not combined.
1.65 = The conversion factor of ton feed per ton clinker.
Qk = The exhaust flow of the kiln (dscf/ton feed).
Qc = The exhaust flow of the clinker cooler (dscf/ton feed).
Qab = The exhaust flow of the alkali bypass (dscf/ton feed).
Qcm = The exhaust flow of the coal mill (dscf/ton feed).
7000 = The conversion factor for grains (gr) per lb.
For new kilns that combine kiln exhaust, clinker cooler gas and/or coal mill and alkali bypass exhaust, the limit is calculated using Equation 2 of this section:
Where:
PMalt = Alternative PM emission limit for commingled sources.
0.002 = The PM exhaust concentration (gr/dscf) equivalent to 0.020 lb per ton clinker where clinker cooler and kiln exhaust gas are not combined.
1.65 = The conversion factor of ton feed per ton clinker.
Qk = The exhaust flow of the kiln (dscf/ton feed).
Qc = The exhaust flow of the clinker cooler (dscf/ton feed).
Qab = The exhaust flow of the alkali bypass (dscf/ton feed).
Qcm = The exhaust flow of the coal mill (dscf/ton feed).
7000 = The conversion factor for gr per lb.
