Placing a dispersion assembly near an elbow (see Figure 60-1)

• Location A is the best choice. Better absorption occurs on the

downstream side of an elbow than on the upstream side.

• Location B is the second-best choice. Installing upstream of an

elbow can cause wetting at the turning vanes. In cases where it is

structurally impossible to avoid Location B, use a multiple tube

dispersion unit to ensure complete absorption. Also, since more

air flows along the outside of a turn, better absorption occurs if

the humidifier discharges proportionately more steam in that part

of the airstream.

• At both locations, discharging steam against or perpendicular to

the airstream gives slightly better mixing and absorption than

discharging with the airstream.
