DESIGN REQUIREMENTS
1.4.1
Mechanical Cyclone Dust Collector System
Indicate the kind, size, collector arrangement with duct gas distribution
devices, duct transitions, hopper access, walkways, housing access, damper
and damper controls, draft gage and sample portal connections, weight of
each component, and breakdown for shipment. When detail drawings are
submitted without statements describing sectional shipments, it will be
understood that no field assembly of the equipment will be required.
Indicate the arrangement of platforms, walkways, stairways, and fixed
ladders that are required for operation, examination, testing and
maintenance of each dust collector. Indicate the external connections,
location of local controls and remote control panels, anchorages, and
supports required; the dimensions needed for installation and correlation
with other materials and equipment; and foundation and loading information.
Submit the layout drawings for each component showing design and assembly.
Layout drawings shall show each hopper face with all arrangement including
control zones. Submit wiring diagrams and control schematics of all
electrical and pneumatic circuits used.
1.5
OPERATING EXPERIENCE REQUIREMENTS
1.5.1
Equipment
Provide only [a] dust collector[s] which meet[s] all of the operating
experience requirements listed below.
1.5.2
Operating Experience
Manufacturer shall certify that the manufacturer has constructed not less
than three mechanical cyclone type dust collectors of the [multitube
mechanical type] [high-efficiency; large-diameter centrifugal cyclone type]
treating flue gas from [an incinerator] [a boiler] with [automatic]
[manual] combustion control. Each collector shall have performed
satisfactorily, normal maintenance or downtime of the associated [boiler]
[incinerator] included, for a period of not less than 2 years treating at
least [_____] L/s acfm of inlet gas at a temperature of at least [_____]
degrees C F, with inlet dust loading of at least [_____] grams per liter
grains per acf and outlet dust loading of at most [_____] grams per liter
grains per acf. In determining this experience:
a.
Only collection of fly ash as produced by [coal-fired boilers]
[oil-fired boilers] [refuse-fired waste disposal incinerator] is
considered as equivalent experience.
b.
Only experience at the approximate flow gas volume, flue gas
temperature and inlet dust loading is acceptable.
1.6
MANUFACTURER'S FIELD REPRESENTATIVE
Furnish the services of [a] field representative(s) specifically trained by
the manufacturer to assist installers of their equipment. Field
representative(s) shall be at the erection site during all phases of the
installation including unloading, hauling, storing, cleaning, erecting, and
testing. It is the responsibility of the field representative(s) to assist
the installer during the erection of [the] dust collector(s) and to assure
both parties that dust collector(s) [is] [are] being installed in
accordance with the dust collector manufacturer's recommendations. The
