Technical data
The dimensions of the shafts must ensure a minimum gap be-
tween the outer wall of the smoke duct and the inner wall of the
shaft: 30 mm for circular section shafts and 20 mm in the event of
a square section shaft (Fig. 37).
Maximum 2 changes of direction are allowed on the vertical sec-
tion of the flue system with a maximum clearance angle of 30°
with respect to the vertical.
The maximum vertical extension using a Ø 60 ducting system is
12.9 m, the maximum extension includes 1 bend Ø 60/100 at 90°,
1 m of horizontal pipe Ø 60/100, 1 x 90° ducted bend Ø 60 and the
roof terminal for ducting.
37
The maximum vertical extension using a Ø 80 rigid ducting sys-
tem is 28 m, the maximum extension includes 1 adapter from
Ø 60/100 to Ø 80/125, 1 bend Ø 80/125 of 87°, 1 m of pipe
Ø 80/125 in horizontal, 1 x 90° ducted bend Ø 80 and the roof ter-
minal for ducting.
To determine the C
described (Fig. 39) one must consider the following head losses:
- 1 m of concentric pipe Ø 80/125 = 1.8 m of rigid ducted pipe
Ø 80 and 0.7 m of flexible ducted pipe Ø 80;
- 1 curve Ø 80 of 87° = 2.1 m of rigid ducted pipe Ø 80 and 0.9 m
of flexible ducted pipe Ø 80.
Consequently one must subtract the equivalent length of the part
added to the 28 m available.
