How Air Burners Work

Air Curtain Burners use advanced combustion technology to significantly reduce waste volume while minimizing environmental impact:

  1. The Air Curtain: When the machine is fully up to speed and running, the air coming out of the manifold creates an “air” lid over the top of the FireBox. This “lid” traps the particles of smoke under the air curtain for fractions of a second causing them to reburn. This secondary burn reduces the smoke particle size so small it generally looks like heat waves coming out of the FireBox.
  2. Accelerated Combustion: The whole purpose of the air curtain is to create this secondary burn. The extra air helps oxygenate the fire to burn as fast as possible.
  3. Reduced Emissions: By optimizing the combustion process, Air Burners significantly reduce the release of smoke and pollutants compared to open burning. The result? Cleaner, faster, and more efficient waste management.

Applications for Air Curtain Burners

  1. Green Waste Processing at Transfer Stations: Urban areas without access to landfills or other disposal facilities can use Air Burners at transfer stations to handle green waste like tree trimmings, yard debris, and storm-generated materials. Air Burners provide an efficient, eco-friendly solution that helps cities maintain cleanliness while adhering to environmental regulations.
  2. Remote Construction Sites: In off-grid construction projects, debris disposal is often a logistical challenge. Air Burners allow contractors to process waste directly on-site, converting it into ash that can be used as a soil enhancer, reducing transport costs and time.
  3. Rural Land Development: Clearing land for agriculture or residential use produces large volumes of vegetative debris. Air Burners provide an efficient way to process this waste into ash, which can then be reintegrated into the soil to boost fertility.

Air Burners supplied its largest FireBox models (S-327) to the Texas Department of Emergency Management and Texas A&M University, helping to clear approximately 2 million cubic yards of vegetative waste in just a few months. The project, led by Director of Sales Michael Schmitt, demonstrated the efficiency and reliability of Air Burners in large-scale cleanup operations.

Lessons from Hurricane Michael

The Florida Forest Service has been working since 2018 to remove the estimated 2.8 million acres of timber taken down by the hurricane. In March 2022, the Bertha Swamp Road Fire in Florida’s Panhandle burned over 33,000 acres, fueled significantly by debris from Hurricane Michael. Unlike Texas’ quick recovery and Florida’s earlier success with Hurricane Irma, Northern Florida has faced challenges due to inefficient contracts with local contractors. Instead of collaborating, contractors moved debris between sites without fully addressing the cleanup, resulting in costly delays and even a recent out-of-control fire.

The Florida Forest Service has identified 233 communities at severe risk of wildfire damage due to the increased fuel loads from Hurricane Michael. Emphasizing the critical need for Air Burners, which streamline disaster recovery by providing on-site waste elimination without the logistical hurdles of grinding and hauling.
