If you run a biomass boiler, you know the headache: the temperature looks fine on the sensors, but your bags are failing way too early. In biomass systems, heat isn’t the only killer. You’re dealing with high moisture, sticky fly ash, and those nasty alkali metals (K, Na) that eat through low-grade filter bags for high-temperature applications like acid.
How Aokai Solves These Boiler Filter Bags Technical Pain Points
We don’t just sell you a bag and hope for the best. Aokai ENVIRONTEC tackles these biomass-specific issues with actual manufacturing logic for boiler filter bags:
-
Fighting “Sticky Dust” : Biomass ash loves to stick. We apply a PTFE micro-porous membrane to our boiler filter bags. This creates a super-smooth surface so the dust cake drops off instantly during the pulse-jet, keeping your pressure drop low and saving you on compressed air.
-
Neutralizing Chemical Attack : To stop alkali metals from rotting the fabric of your filter bags for high-temperature, we use a high-density needle punching technique with specialized fiber blends. We also ensure each fiber is encapsulated with an oil and water repellent (OWR) finish, protecting the “heart” of the boiler filter bags from moisture.
-
Spark Defense We mix flame-retardant fibers directly into the felt. This is part of the filter bags for high-temperature DNA, providing a critical buffer when stray embers hit the media.
Aokai Recommended Filter Bags for High-Temperature & Biomass
If you want your baghouse to stop eating your maintenance budget, here are our field-proven boiler filter bags:
-
PPS/PTFE Blended Felt: The “Workhorse.” It combines the cost-effectiveness of PPS with the extreme chemical resistance of PTFE. The most balanced filter bags for high-temperature in biomass plants.
-
100% PTFE Boiler Filter Bags: The “Final Solution.” When the fuel source is inconsistent and the flue gas is highly aggressive, these filter bags for high-temperature are virtually indestructible.
Filter Bags for High-Temperature -
P84 Composite Bags: Best for boilers with fine ash and temperature spikes. Its trilobal fiber structure is a game-changer for boiler filter bags emission control.
