Cyclonic Ash Removal
Cyclonic ash removal is a high-efficiency method of separating fine ash and particulate matter from flue gases
What is Cyclonic Ash Removal?
How It Works
Our cyclonic system pulls hot flue gas into a tapered chamber where it spirals downward. As the gas spins, heavier ash and dust particles are flung to the walls and drop into a collection bin or auger. Cleaned gas exits through the top, while the ash is automatically removed, ensuring continuous operation without downtime.
Built for Industrial Duty
• Auger discharge systems
• Rotary airlocks
• Ash bins or tote dumping
Low maintenance: No filters or moving parts inside the cyclone
Increased uptime: Prevents ash buildup in your heat exchanger and ducting
Improved performance: Keeps draft fans and sensors cleaner
Scalable: Available in multiple sizes to match your BTU output
Why Choose Us?
Canada’s most stringent environmental jurisdictions impose rigorous particulate and emissions standards—but our cyclonic ash removal systems are engineered to exceed them, even under the toughest provincial mandates.
The SCW Advantage:
- Guaranteed compliance in every province—no custom adjustments needed.
- Engineered for scalability, with modular upgrades to meet future regulatory tightening.
- Proven performance, with documented testing that routinely surpasses regulatory minimums.
Meets Federal CEPA thresholds
Our units reliably reduce particulate matter (PM) to below 258 ng/J input, with up to 90 % total PM removal, aligning with or surpassing the Canadian Environmental Protection Act (CEPA) guidelines
Advanced NOₓ and SO₂ control integration
Our cyclone modules integrate seamlessly with selective catalytic/non-catalytic reduction (SCR/SNCR) systems to help boilers meet Multi-Sector Air Pollutants Regulation limits—such as NOₓ emission intensities below 26 g/GJ and SO₂ removal ≥ 90 %, capped at ~520 ng/J
Compliant across provinces
In Ontario, BC, Alberta, and Quebec, small biomass combustors (<3 MW) must install PM controls per provincial regulations. SCW’s cyclones consistently meet or outperform these standards, including BC’s industrial best-achievable emission limits
Future-ready for tightening standards
As Canada moves toward BAT-level standards mirroring U.S. NSPS and European directives—like reducing PM under 50 ng/J and SO₂ to 70–95 % removal—you’ll already be ahead of the curve
Proven Emissions Compliance – Even in the Strictest Provinces
Cyclonic ash removal is a high-efficiency method of separating fine ash and particulate matter from flue gases. Using centrifugal force inside a specially designed cyclone separator, ash particles are spun out of the airflow and collected for easy disposal. This keeps your system cleaner, reduces maintenance, and protects downstream equipment.
Independent Testing & Verification
Each of our systems can be third-party tested using:
• EPA Method 5 for particulate matter (PM)
• Method 7E/10 for NOₓ and CO
• Method 6/8 for SO₂ and acid gases
We maintain partnerships with certified stack testing firms and can supply test reports upon request.
Typical Real-World Test Results
• Particulate Matter (PM): Below 50 ng/J input
• Carbon Monoxide (CO): <150 ppm @ 7% O₂
• Nitrogen Oxides (NOₓ): <120 ppm @ 7% O₂ (pre-SCR)
• Sulphur Dioxide (SO₂): >90% removal when paired with a dry scrubber
Why This Matters
• Ambient air quality benchmarks
• Point-source emission limits
• Permit-ready documentation for installation in regulated zones
