Perform CLD quench-check calculations as follows:
Where:
quench = amount of CLD quench.
[XI]NOdry = concentration of NO upstream of a humidity generator, according to § 1065.370(e)(4) .
[XI]NOwet = measured concentration of NO downstream of a humidity generator, according to § 1065.370(e)(9) .
[XI]H2Oexp = maximum expected mole fraction of water during emission testing, according to paragraph (b) of this section.
[XI]H2Omeas = measured mole fraction of water during the quench verification, according to § 1065.370(e)(7) .
[XI]NOmeas = measured concentration of NO when NO span gas is blended with CO2 span gas, according to § 1065.370(d)(10) .
[XI]NOact = actual concentration of NO when NO span gas is blended with CO2 span gas, according to § 1065.370(d)(11) and calculated according to Eq. 1065.675-2.
[XI]CO2exp = maximum expected concentration of CO2 during emission testing, according to paragraph (c) of this section.
[XI]CO2act = actual concentration of CO2 when NO span gas is blended with CO2 span gas, according to § 1065.370(d)(9) .
Where:
[XI]NOspan = the NO span gas concentration input to the gas divider, according to § 1065.370(d)(5) .
[XI]CO2span = the CO2 span gas concentration input to the gas divider, according to § 1065.370(d)(4) .
Example:
[XI]NOdry = 1800.0 [MICRO]mol/mol
[XI]NOwet = 1739.6 [MICRO]mol/mol
[XI]H2Oexp = 0.030 mol/mol
[XI]H2Omeas = 0.030 mol/mol
[XI]NOmeas = 1515.2 [MICRO]mol/mol
[XI]NOspan = 3001.6 [MICRO]mol/mol
[XI]CO2exp = 3.2%
[XI]CO2span = 6.1%
[XI]CO2act = 2.98%
quench = (-0.0036655-0.014020171) · 100% = -1.7685671%
