4.13.7 qA & Excess Air Screen

�

The qA reading is a calculation of stack loss in percent.

The EXCESS AIR (LAMBDA) reading is the calculation of the percentage

of extra air that is available in the combustion chamber above the theoreti-

cal amount needed for perfect combustion.

4.13.8 TL & Eta Screen

The TL reading is the combustion-air temperature that is used for ef-

ficiency and qA calculations. This temperature is measured by either the

optional T-AIR thermocouple on a continuous basis, or by the T-STACK

thermocouple during start-up (refer to Section 4.2.1). If neither thermo-

couple is installed when the analyzer is turned ON, then this temperature

reading comes from a temperature sensor located inside the analyzer.

The Eta reading is the calculated percent efficiency as referenced to a low
