Option Heated Probe For Soot Measurement - Ecom EN3 Instruction Manual

1.5. Option heated probe for soot measurement

In order to perform a measurement of the soot content in the flue gas from
oil firing systems, a filter paper is introduced into the exhaust path of the
probe where the soot deposits during the measurement.
On the basis of the deposited amount of soot on the filter paper (blackening),
it is possible to compare optically with a scale, which is the soot number. This
makes it possible to evaluate the amount of soot in the flue gas.
The filter paper is heated in the probe to prevent the flue gas from cooling
too much. This cooling of the flue gas would lead to condensation of water
vapour from the flue gas and will distort the result of the measurement.
NOTE
As an alternative to the heated probe, a hand soot pump can be
used. The possible condensation of water vapour is however not pre-
vented with a hand soot pump.
NOTE
For further information on the procedure for soot measurement with
the heated probe, please refer to chapter "4.7 Soot...Oil trace".
