NOTE:
Do not insert immediately, the analyzer
probe at the sampling point, to avoid
saturation of the analyzer.
It is also important to make analysis of
combustion air,
(Observing that concentration of oxygen
is
O2 = 20.8%
Tolerance 0.2 - 0.4%).
This is to exclude possibility of smoke
recirculation.

To determine the combustion efficiency
one must make the following measurements:
- measurement of the combustion air temperature
taken in the relevant hole
1
.
COAXIAL PIPES
SEPARATE PIPES
PIPES Ø 80 TYPE B23
- measurement of the flue gas temperature and
content of CO
2
taken in the relevant hole
2
.
Take the measurements with the generator in
steady state conditions (see par. 3.11.1).
