Tire Skewer Suspension Burning
AFS Technology’s patented Tire Skewer Suspension Burner takes advantage of the doughnut shape of the tire to hold it in suspension for 100% fixed carbon burnout. With this method, multiple tires can be securely suspended in the high gas velocities of the riser duct or feed shelf hood for maximum NOx reduction benefit. Field testing has demonstrated feed rates exceeding 3 tons/hr for sustained periods, and possibly working over 6 tons/hr using two burners.
KILN TYPES: Precalciners
FUEL INJECTION LOCATION: Calciner, above tertiary air. Riser duct or feed shelf hood, below tertiary air
- Temperature: 900 – 1100 Degrees Celsius
- Gas Velocity: 20 – 35 Meters per Second
- Oxygen: <2%
FUEL FEED RATE: 3 tons per hour (t/h), per burner.
FUEL SPECIFICATIONS: Whole scrap tires up to 48 in (1220 mm) in diameter.
NOx REDUCTION POTENTIAL: Up to 40%
SYSTEM OPTIONS: Wire Cutting option drops tire wire onto the feed shelf. Wire Retrieval option removes wire from the kiln process.
