K.4.2 Calculation formulae
CCaarrbboonn ddiiooxxiiddee::
CO2 = C02max: Maximum carbon dioxide
specific to fuel
21%: Oxygen level of air
O2: Measured oxygen level in %
FFlluuee ggaass lloossss::
qA =
(
(FT-AT) x ( + B )
)
- Kk FT: Flue gas temperature
AT: Ambient temperature
A2/B: Fuel-specific parameters
21%: Oxygen level of air
O2: Measured oxygen level in %
Kk: Calculated value
allowing for
regained condensate heat
if dewpoint level is not
reached
(for condensing furnaces).
