Industry solution

Power Plants

Air handling equipment, baghouse filters, cyclone separators, and hot-gas expansion joint support for boiler, ash, flue gas auxiliary systems, and fuel preparation lines. Dust load, operating temperature, maintenance access, and emission targets at each process point determine the product selection.

Power Plants equipment scope

Filter, fan, filter bag, filter cage and auxiliary equipment selection by process

In power plants, boiler flue gas, biomass/coal preparation, and ash handling points carry different temperature, chemical load, and explosion risks. The filter, air handling equipment, hot-gas expansion joint, bag media, and ash discharge are sized as a single integrated system.

Process filtration, fan and equipment scope for Power Plants

Process-based system approach

The filter housing, fan, ductwork, filter element, pulse-jet system and discharge/conveying equipment are not independent of one another; they are evaluated as components of the same operating point.

Information clarified before quoting

Flue gas flow rate: Minimum/nominal/maximum flow depending on boiler load
Temperature/dew point: Continuous, peak, and acid dew point
Gas chemistry: SOx, moisture, oxygen, and reagent injection
Ash load: Inlet dust concentration and particle size distribution
Pressure drop: Duct + filter + stack system curve

Equipment scope by process point

Process Dew Point	Filter / dust-fume solution	Fan, ductwork and conveying equipment	Critical selection grade
Boiler and flue gas	Dust retention suited to the baghouse filter or process conditions	Boiler ID fan, hot-gas duct, and expansion joint	Acid dew point, SOx/NOx environment, temperature, and corrosion
Coal/biomass preparation	Crusher-mill and transfer dedusting filter	Fuel preparation air-handling equipment, damper, and explosion safety	Combustible dust, moisture, spark, and ATEX assessment
Fly ash silo	Silo-top pulse-jet filter	Silo venting fan equipment, rotary valve/air slide	Very fine ash, high ΔP, and peak flow during filling
Bottom ash and ash transfer	Local filters at transfer points	Screw conveyor, elevator, enclosed conveyor, and extraction air handling equipment	Abrasiveness, hot ash, and sealing
Lime/reagent feeding	Dosing and silo filters	Pneumatic transfer air handling equipment, rotary valve, and screw conveyor	Fine reactive dust, humidity, and dosing continuity

How do we determine capacity and technical specifications?

Exact capacity is not set by a catalog name; it is determined by process flow rate, system pressure, temperature, material/dust behavior and discharge continuity.

technical data	Required site / process information	Impact on selection
Flue gas flow rate	Minimum/nominal/maximum flow rate based on boiler load	Determined by the filter area and the ID fan.
Temperature/dew point	Continuous, peak, and acid dew point	Determines corrosion resistance and bag media.
Gas chemistry	SOx, moisture, oxygen, and reagent injection	Changes the media and material selection.
Ash load	Inlet dust concentration and particle distribution	Affects pre-separation, cleaning, and hopper design.
Pressure loss	Duct + filter + stack system curve	Determines air handling equipment power and energy consumption.
