Biomass combustion inevitably brings slagging and fouling
- 01
Biomass fuels contain large amounts of alkali metals such as K (potassium) and Na (sodium).
- 02
Unable to withstand the high-temperature environment inside the boiler, these alkali components melt and adhere to surfaces, causing slagging and fouling.
- 03
K-Ment reacts with these alkali components to form high-melting-point compounds that are discharged as ash, preventing slagging and fouling at the source.
K-Ment reacts with alkali compounds to neutralize them
The aluminosilicate at the core of K-Ment adsorbs and reacts with alkali compounds vaporized during combustion. This produces minerals such as Kalsilite and Leucite—with melting points far above boiler temperatures—so that the alkali compounds are discharged as ash rather than adhering to boiler surfaces.
Kalsilite Formation Mechanism
- 01Al₂O₃·2SiO₂ + 2KCl + H₂O → 2KAlSiO₄ + 2HCl
- 02Al₂O₃·2SiO₂ + K₂SO₄ → 2KAlSiO₄ + SO₃
- 03Al₂O₃·2SiO₂ + K₂O → 2KAlSiO₄
- 04Al₂O₃·2SiO₂ + 2KOH → 2KAlSiO₄ + H₂O
Leucite Formation Mechanism
- 01Al₂O₃·4SiO₂ + 2KCl + H₂O → 2KAlSi₂O₆ + 2HCl
- 02Al₂O₃·4SiO₂ + K₂SO₄ → 2KAlSi₂O₆ + SO₃
- 03Al₂O₃·4SiO₂ + K₂O → 2KAlSi₂O₆
- 04Al₂O₃·4SiO₂ + 2KOH → 2KAlSi₂O₆ + H₂O
K-Ment delivers exceptional performance
Specific Surface Area Comparison
(Unit: m²/g)
With approximately five times the specific surface area of commercially available additives, K-Ment offers significantly superior adsorption performance against alkali compounds.
Reaction Efficiency Comparison
(Unit: %)
Conventional additives have an alumina content of 30% or less, meaning only about two-thirds of the additive participates in the chemical reaction while the rest is discarded unreacted.
K-Ment is engineered with an alumina content of 40% or higher, maximizing reaction efficiency with alkali compounds.
Reaction Participation Ratio
Empty area indicates the proportion that does not participate in the reaction and is discharged as ash
The boiler surface is the proof
Before K-Ment, slagging and fouling accumulated thickly on the boiler water tubes. After K-Ment was introduced, these deposits no longer adhere to surfaces and are discharged as ash.
