Fabric Filters

Best-in-class technology

Alstom Fabric Filters (FF)
deliver enhanced gas
absorption and reduced
fine particle emissions –
a flexible alternative to
Electrostatic Precipitators
(ESPs) in processes with
high variability of dust or
inlet conditions.

Customer benefits
ADAPTABLE
A range of high- and low-ratio models,
sizes and filter media to perfectly suit
your configuration and process.
CONSISTENT
Performance unaffected by variations
of fuel or inlet conditions.

Consistent lower compliance cost
for dynamic environments
In today’s dynamic market, operational and fuel flexibility is increasingly
important while air quality regulations are becoming more stringent. Alstom’s
comprehensive range of Fabric Filters offer a flexible alternative to Electrostatic
Precipitators (ESP) when the dust characteristics are challenging, unknown
or variable. They deliver a consistently high level of emission control regardless
of fuel composition or inlet rates.
To meet today’s strict environmental standards, Alstom’s Fabric Filters can remove
99.97% or more of particulate matter including ultrafine particles of less than
2.5 micron diameter and are suitable for a wide range of industrial applications
requiring particulate collection.
Fabric Filters may be used as stand-alone technology or in integrated applications.
For example in Dry Flue Gas Desulphurisation (downstream of the Spray Dryer
Absorber (SDA) or in the NID™ Dry FGD system), in dry scrubbing of aluminium
smelter pot gases (Abart™) or as the principal and polishing filters in mercury control
solutions (KNX™, Mer-Cure™, Filsorption).
In addition to allowing greater customer choice and customisation, Alstom Mega
Fabric Filter designs occupy a smaller footprint compared to other designs, require
lower initial capital investment and save on delivery and installation times.
