Length I
D
of the usable steam manifold depends on the dimen-
sions of the air duct. The length of the absorption distance can
be reduced by using multiple steam manifolds (also see section
on the steam manifold).
Method:
Graphically determine absorption distance B
N
using the absorp-
tion distance nomogram (also see Section „Absorption Distance
Nomogramm“). Enter the value of the parameters enumerated
above into the respective quadrants. The resulting point of inter-
section indicates the value of the desired absorption distance
B
N
.
