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
It deals primarily with water tube boilers with induced draft
and forced draft fans or boilers containing only forced draft fans.
ICE CT-M Series cooling towers feature an induced draft
design that is said to ensure that a low-static, low-energy fan will complete the job and avoid the water leaks typical in forced draft towers, according to the company.
Cleaning of cyclones, precipitators, air preheaters, induced draft
fans, stacks, and associated ductwork was checked by the consultant through visual review, followed by white glove inspection.
A small induced draft
fan rated at approximately 1,000 [ft.sup.3]/min and 4 in Hg (equivalent to 55 in [H.sub.2]O) static pressure at the surface encourages the flow.
One is to install an "induced draft
" furnace or water heater, which simply means that the exhaust flue includes a built-in fan that blows the fumes up the chimney.
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.
