Air Dynamics Combustible Dust Collection Systems are designed to your specific Combustible
dust application while maintaining compliance with NFPA standards and OSHA regulations.
Combustible metal dusts require special collection methods to insure worker safety AND Plant
sustainability.
Read more about combustible metal dust collection as outlined by the National Fire Protection Association
below.
Standard systems have the following features
Combustible Dust Collectors are manufactured in any size or shape to fit your plant layout. Combustible
Dust Collectors range in size from 800 cfm to 50,000 cfm.
Combustible Metal Dust Collection
When Choosing a Dust Collector for your Combustible Metal Dust application
NFPA 484 summarizes.
Dry-Type Dust Collectors require the following attributes when collecting combustible
metal dusts.
-
Must be provided with deflagration vents
-
Fabricated using conductive material, grounded and bonded
-
Exhausted outdoors
-
Designed so that accumulation of dust or water inside the system is avoided
-
Collected material must be removed on a daily basis
-
Electrostatic collectors are NOT permitted
-
Discharged into metal containers that shall be promptly and tightly covered to avoid
the creation of airborne fugitive dust
Wet-Type Dust Collectors
-
The dust collector shall be arranged so that the dust laden airstream is thoroughly
scrubbed by the liquid to achieve the desired efficiency
-
The use of additional dry filter medium, either downstream or combined with a wet collector, shall
not be permitted
-
The dust collector shall be arranged so that contact between dust particles and parts moving
at high speed is prevented (Fan must be located on clean air side)
-
The exhaust vent shall terminate outside the building and be securely fastened
a. The duct shall be as short and straight as possible and shall be designed to withstand the same
explosion pressure as the wet-type dust collector
b. The exhaust vent shall be inspected and cleaned to prevent buildup of highly combustible
deposits of metal dusts on the interior surfaces of the duct
c. Cleaned air shall be permitted to be returned to the work area where tests conducted by
an approved testing organization prove the collector’s efficiency is great enough to
provide both personnel and property safety in the particular installation, with
regard to particulate matter in the cleaned air and accumulations of
particulate matter or hydrogen in the work area
-
Sludge shall be removed from the collector on a regular schedule
a. The sump of water wet-type dust collectors shall be ventilated from the top of the collector
at all times.
