Rack Suspension Burning
Our Rack Suspension Burner is designed to feed whole tyres onto a high-temperature alloy Suspension Rack – also known as the “fork” or “fingers” – which enables the tyre to remain in suspension while burning inside the walls of the calciner. Typically placed above the tertiary air duct, ample oxygen levels aid in the complete combustion of fixed fuel carbon well above the feed shelf. Multiple burners can be installed to achieve tire fuel substitution rates over four times greater than feed shelf firing methods.
KILN TYPES: 5 or 6-Stage Inline Precalciners; Custom design for certain types of Separate Line Calciners.
FUEL INJECTION LOCATION: In the calciner, typically above the tertiary air.
- Temperature: 900 – 1100 Degrees Celsius
