6.8.2. Flue gas tubes Melbury HE
We recommend the use of flue gas tubes made from acid-resistant, non-corrosive materials. The tube must be
laid and introduced in the chimney to an inclination of 30-45° to minimize pressure loss. The tube will have to be
inserted in such a way as to prevent any condensation reversal from the chimney down into the boiler. To avoid
vibration transmission, combustion gas tubes must be fitted with adequate sleeve tubes or clamps. Connections
exceeding 1 m in length should be insulated.
At the same time, ensure that the measuring pipes extend beyond the insulation and that flanges and cleaning
covers remain accessible.
The chimney must be designed so that it is gas and pressure-tight as well as moisture-insensitive and acid-
resistant.
6.8.3. Flue gas tubes Melbury C
Depending on the return temperature, the flue gases are cooled below the dew point in the recuperator and leave
the boiler with 100% moisture. As a result of the flue gas cooling in the flue gas tube, more condensate is
eliminated. The flue gas unit must therefore be absolutely acid-resistant and condensate-tight, in addition to being
gas and pressure-tight.
The tube must be laid and introduced in the chimney to an inclination of 30-45° to minimize pressure loss. To
avoid vibration transmission, combustion gas tubes must be fitted with adequate sleeve tubes or clamps.
Connections exceeding 1 m in length should be insulated. At the same time, ensure that the measuring pipes
