CADENCE APPLICATIONS Cement kilns are the most efficient

and cost-effective way to recycle whole scrap tires as energy. or more than 30 years, Cadence has been a technology leader in the cement industry. Our patented Fuel Injector and Mixing Technologies can be found hard at work on cement kilns throughout the world. As energy costs increase and emission requirements tighten, our world

wide network of licensees expands because cement kiln operators know Cadence technologies have proven to be a fast, cost-effective way to meet business and environmental goals. Our innovative tech

The Fuel Injector can be quickly and easily fitted to the calcining zone of a cement kiln. Waste-derived fuels, such as whole scrap tires are placed on the apparatus which rotates with the kiln. As the Fuel Injector reaches the vertical position, a mechanism allows the Since 1975, Cadence has been a leading provider of combustion technology and alternate fuels to

the worldwide cement industry.

# 2 S N C R STRATIFIED KILN GASSES CONTRIBUTE TO EMISSIONS IN LONG AND PH/PC KILNS Mixing Air breaks up stratification, improves combustion and permits more alternate fuel use.

Higher temperature oxygen-rich gasses tend to travel along the top of the kiln while cooler, carbon dioxide-rich gasses tend to travel along the bottom. This gas stratification inhibits combustion and contributes to emissions. When Mixing Air is added, opposing streams of high velocity air cause the stratified kiln gas layers to rotate and mix. This rotation improves combustion, reduces emissions, allows more alternate fuel use and improves kiln stability. • Increased alternate fuels
• Less sulfur buildup
• Improved thermal efficiency
• Better product quality SERIOUS NOx REDUCTION FOR LONG KILNS AND PH/PC KILNS Long kilns have not been able to take full advantage of SNCR’s NOx reducing capability ... until now.

For optimum SNCR performance, two criteria must be met. One: The reducing agent must interact at a precise temperature and location. Two: The reducing agent must be thoroughly mixed with the kiln gasses. Cadence’s SNCR system meets these criteria perfectly. Mix Air injectors are positioned in the exact thermal region and the powerful, swirling, vortex of high pressure air ensures complete dispersion of the reducing agent.

No other SNCR technology is as cost-effective or efficient at lowering NOx emissions in cement kilns. Reduction rates of up to 50% can be achieved in long wet and dry cement kilns, lime kilns and other mineral processing kilns.

Mixing Air OFF PERFORMANCE AVERAGES

ALTERNATE FUELS USED

Whole Tires Mixing Air ON

Mixing Technology Fuel Injector whole tires (or other fuels) to drop into the center of the kiln. Virtually any energy-bearing waste can be used. The Cadence Fuel Injector is a fast, cost-effective, and proven way to add a variety of waste fuels to a cement kiln.

Whole scrap tires are injected at a computer controlled rate through an air lock to the suspension burner where they are used as fuel.

Optional Feed Shelf for additional alternate fuel entry such as whole scrap tires. A Mixing Air Injector effectively mixes the gasses in the calciner for more complete combustion.

Optional Mixing Air Injector adds opposing streams of high-velocity air inside kiln to improve combustion by mixing stratified gasses.

The Suspension Burner from Cadence is breakthrough technology for PH/PC kilns that maximizes a kiln’s waste fuel potential. Now thermal energy in the calciner can be reenergized using suspended scrap tires. The result: • LOWER ENERGY COSTS • REDUCED EMISSIONS • BETTER OPERATING KILN
