Direct emission into the atmosphere
Natural draught boilers can discharge flue gas directly into the atmosphere via a duct which goes through the outside walls of the building and
ends with an anti-wind gust device terminal.
The flue gas exhaust duct is to comply with the following requirements:
- its sub-horizontal part inside the building must be as short as possible (not longer than 1,000 mm);
- it is not to have more than 2 direction changes;
- it can host only one single boiler flue gas exhaust system;
- its section, which is passing through the wall is to be protected by a sheath duct; the part of the sheath duct facing the inside of the building is to
be sealed, while the part facing outwards is to be left open;
- its end section, on which the terminal is to installed, is to protrude from the wall of the building for a length of a
least twice the diameter of the duct;
- the terminal is to be positioned no less than 1.5 meters higher than the flue gas exhaust duct from the boiler (see pic. 6).
