What Is an Air Curtain Burner?
Dealing with large piles of wood waste and vegetation has always been a headache for municipalities, forestry teams, and contractors. Open burning might be fast, but it’s notorious for harmful emissions and embers flying around. Landfilling? It’s costly and bad for the environment.
That’s where air curtain burners come into play.
These machines offer a faster, cleaner, and more budget-friendly way to handle waste — all while staying in line with strict EPA and USDA standards.
How Air Curtain Burners Work
Also known as FireBoxes, air curtain burners use high-speed air to create an invisible “curtain” over the burn chamber. This barrier traps smoke and particles long enough for a second combustion to occur.
This reburning process significantly cuts down on visible smoke and breaks down particles until they’re nearly invisible — just shimmering heat waves. The constant airflow also feeds the fire more oxygen, creating a hotter, more efficient burn that handles waste cleanly and quickly.
The result?
- Drastically reduced smoke
- Cleaner air output
- Up to 98% reduction in waste volume
These systems are tested and trusted by the EPA, USDA Forest Service, Department of Energy, Army Corp of Engineers, Bureau of Land Management, FEMA, etc as the cleanest and fastest wood waste disposal tech on the market.

Core Components of an Air Curtain Burner
- FireBox Chamber – Heat-resistant thermal ceramic lined burn chamber that holds the debris
- High-Velocity Fan System – Generates the air curtain to trap and reburn smoke
- Power Unit – EPA Tier 4F diesel or electric motor powers the system
Environmental Benefits
Air curtain burners don’t just work — they work responsibly. Compared to open burning, grinding or hauling, composting or landfilling, they deliver:
- Up to 98% fewer airborne particles (based on EPA and USDA data)
- Carbon-neutral burns using clean wood waste — no added fuel
- Zero methane emissions (a key problem with landfills)
- Byproducts like ash and biochar that enrich soil and improve water retention
With wildfire risks increasing, the USDA considers air curtain burners a critical tool for fuel reduction and land management.
Cost Savings & Performance Metrics
Beyond the environmental wins, air curtain burners deliver real savings:
- Landfill Alternative – Save 35%+ by avoiding haul and tipping fees; in high-cost counties, savings can hit six figures or more
- Case Study: Solar Farm – Switching to an S330 FireBox slashed disposal costs from $1.22M to $306K — over $900K in savings
- Efficiency – Handles up to 13 tons of material per hour, using as little as 2.4 gallons of fuel per hour
Regulatory Compliance Made Easy
Air Curtain Burners are designed for hassle-free compliance:
- EPA – Meets Clean Air Act opacity rules; as of 2024, easier permitting for units that burn only wood waste or yard debris
- USDA Forest Service – Approved for vegetation and wildfire fuel reduction
- FEMA – Used for disaster debris response and cleanup
- Local Governments – Trusted by municipalities nationwide as a replacement for open burning
