Technical Data & FAQ
P84 needle felt is widely used in demanding dust filtration systems where high temperatures, corrosive flue gases, and strict emission requirements are present. Thanks to its outstanding heat resistance, chemical stability, and high filtration efficiency, it performs exceptionally well in harsh industrial environments.
1. Waste Incineration Plants
P84 is one of the most commonly used filtration materials in municipal and industrial waste incinerators due to:
High-temperature resistance
Excellent filtration efficiency for fine particles
Strong resistance to acidic flue gases (HCl, SO₂, NOx)
Its trilobal fiber shape also enhances surface filtration, significantly reducing emissions.
2. Cement Industry
Used in:
Kiln head & kiln tail dust collectors
Clinker coolers
Packhouse dust collectors
P84 maintains stable filtration performance in environments with high dust loads and fluctuating temperatures.
3. Chemical and Petrochemical Industry
Ideal for filtration of corrosive gases and high-temperature fumes generated during:
Chemical decomposition
Polymer production
Catalyst recovery
Chemical reactors
Its strong resistance to acids, alkalis, and oxidizing gases provides long service life.
4. Coal-Fired & Biomass Power Plants
Applied in:
Boiler dust collectors
Electrostatic precipitator (ESP) retrofit systems
High-temperature baghouses
P84 ensures efficient collection of fine ash and stable performance in complex flue gas compositions.
5. Metallurgy & Smelting
Effective in environments containing:
Metal fumes
High-temperature particulates
Corrosive gas emissions
Commonly used in aluminum, steel, and non-ferrous metal production lines.
6. High-Temperature Drying and Kilns
Used in industrial dryers requiring consistent filtration at elevated temperatures, such as:
Rotary dryers
Spray dryers
Ceramic and brick kilns
P84 provides reliable operation during long-term thermal cycles.
7. Hazardous Waste & Medical Waste Treatment
P84 is ideal for facilities that require strict emission control and stable performance in toxic and chemically aggressive environments.
8. Other Applications
Carbon black production
Asphalt mixing plants
Lime kilns
Glass manufacturing
Anywhere high-temperature, corrosive flue gas filtration is required, P84 needle felt is a preferred material.
