Measuring the Ventilation Loss
Fig. 43: S-tube probe
The ventilation loss has to be measured 30 se-
conds after burn-out. It is based on the measure-
ment of the air speed and of the temperature of
the residual core flow. The test fulfills the require-
ments of DIN EN 15378, national annex, concern-
ing the evaluation of the ventilation loss of boilers.
