The induced draft
fan model is expressed as follows .
Hence, the motors for the forced and induced draft
fans operate below the optimum performance level.
In an induced draft
system, several blower outputs may pipe to a manifold, which feeds a biofilter, often through ductwork similar to that used in HVAC systems.
The station has a single cooling tower, with twelve individual induced draft
Each precipitator received 10 to 12 white glove inspections; each cyclone six to eight; each preheater four to six; each induced draft
fan and associated ductwork two to four; and each stack five to seven.
A small induced draft
fan rated at approximately 1,000 cfm and 55 in-H [subscript]2 O static pressure at the surface encourages the flow.
As you might expect, both the induced draft
and closed combustion systems cost more than those that rely on natural drafts.

It is also equipped with a variable speed, induced draft
fan at the tower outlet to automatically maintain the optimum flue gas static set point at the tower outlet.
Polyethylene noncorrosive assembled package cooling towers include Pioneer forced-draft line from 10 to 100 tons, the Paragon induced draft
line from 100 to 250 tons, and the TM series induced draft
line from 250 to 2000 tons in multi-fan modules designed and shipped factory complete.
This article summarizes recent field erosion experiments conducted by NorskeCanada's Port Alberni Division on their power boiler's induced draft
(ID) fan, in an attempt to reduce severe wear, increase fan productivity, and prolong intervals between planned outages.
