Technical data
The dimensions of the shafts must ensure a minimum gap between 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. 28).
Maximum 2 changes of direction are allowed on the vertical section of the flue system with a maximum clearance angle of 30° with re-
spect to the vertical.
The maximum vertical extension using a Ø 60 ducting system is 13 m, the maximum extension includes 1 bend Ø 60/100 at 90°, 1 m of
horizontal pipe Ø 60/100, 1 x 90° Ø 60 ducted bend and the roof terminal for ducting.
To determine the C
flue system in configurations other than that described (Fig. 30) one must consider that a 1-metre ducted pipe ac-
93
cording to the indications described has a resistance factor equal to 4.9.
The maximum vertical extension using a rigid Ø 80 ducting system is 30 m; the maximum extension includes 1 adapter Ø 60/100 to Ø
80/125, 1 87° bend Ø 80/125, 1 m of horizontal pipe Ø 80/125, 1 90° Ø 80 ducted bend and the roof terminal for ducting.
To determine the C
flue system in configurations other than that described (Fig. 30) one must consider the following head losses:
93
- 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.
