A PH/PC TECHNOLOGY THAT CAN ACHIEVE
UP TO 40% FUEL SUBSTITUTION RATES
A SIGNIFICANT ENERGY SAVING AND EMISSION REDUCTION
TECHNOLOGY FOR LONG CEMENT KILNS
The Suspension Burner allows PH/PC kiln operators to
take full advantage of their kilns alternative fuel potential.
At work on kilns around the world since 1986, the Mid-Kiln Fuel Injector
is the fastest and most cost-effective way of using solid energy-bearing
waste, such as whole scrap tires, as fuel in long cement kilns.
A Mixing Air Injector
effectively mixes the gasses
in the calciner for more
complete combustion.
Whole scrap tires are
injected at a computer
controlled rate through an
air lock to the suspension
burner where they are
used as fuel.

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
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
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.

SERIOUS NOx REDUCTION FOR LONG KILNS
AND PH/PC KILNS
Mixing Air breaks up stratification, improves combustion
and permits more alternate fuel use.
Long kilns have not been able to take full advantage
of SNCR’s NOx reducing capability ... until now.

CADENCE APPLICATIONS
CANADA
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.
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.
