ROTARY KILN COMBUSTION SYSTEMS
-
Since 1912 Coen Company has specialized in the design, manufacture, servicing and maintenance of burner
equipment and combustion systems. With thousands of installations worldwide, Coen burner equipment and
combustion systems provide optimum performance in a wide variety of applications.

COEN FOR FLEXIBILITY IN FUEL FIRING SYSTEMS
The burner is an important piece of equipment on any kiln
installation, and it must meet the demanding requirements of many
different processes such as lime recovery, cement, magnesite, kaolin,
and a wide variety of other materials. Coen reviews the specific
requirements of these processes in designing the burner system
and provides a burner design that will deliver efficient and reliable
combustion. Even for a given process, wide variations in production,
fuel types, and material properties may require different flame shapes
to optimize material processing. To accommodate this need, Coen
builds into each burner system a wide range of adjustment to allow
the operator to maintain peak production performance at all times.
COENFOR ALTERNATE FUEL CAPABILITY
A Coen kiln burner is well suited and proven for handling alternative
fuels. These alternative fuels can be burned by themselves or
simultaneously with gas or oil firing. Coen can provide a kiln
combustion system for many types of alternative fuels, such as:
Petroleum Coke Non-Condensible Gases
Producer Gas Methanol
Coal Solvents
Woodwaste

Features of the Coen Kiln Burner
DUAL AIR ZONE:
Coen has developed the Dual Air Zone kiln burner for
optimum performance even with difficult to burn fuels. The
outer (secondary) zone can be utilized to transport solid fuels
or a tertiary zone can be added for this purpose creating a
three-zone burner. The inner zone incorporates a proprietary
spinner design which creates a recirculation zone to stabilize
the flame.
MULTIFUEL CAPABILITY:
The Coen burner is designed to handle gas and oil firing
simultaneously or in combination with solid fuels such as
coal, petroleum coke, or wood.
ADJUSTABLE DUAL ZONE GAS BURNER:
For precise flame shape control, Coen has developed the
dual zone gas burner. Adjusting the fuel split between these
two zones allows the operator to adjust the flame to suit his
particular needs.
OIL ATOMIZERS:
Coen can incorporate its full range of oil gun designs into the
burner, which can utilize steam, high pressure air, low pressure
air, gas or straight mechanical atomization methods. These oil
guns atomize wide range of fuels from diesel oil to heavy fuel
oils, with excellent turndown.
LOW PRIMARY AIR:
On kilns with coolers, the Coen burner is designed to use a
minimum of primary air to maximize air from the cooler and
raise efficiency.
PREHEATED PRIMARY AIR:
Hot primary air is a process which has been used on numerous
kilns to increase efficiency and help stabilize difficult fuels.
RUGGED CONSTRUCTION:
All parts exposed to the hot kiln are built of high grade
stainless steel including gas and oil nozzles. The main
primary air tube is thick spuncast with no welds or seams.
Refractory coating for high temperature applications
is available.

COEN FOR TECHNICAL LEADERSHIP
A commitment to technical leadership assures that Coen can
respond quickly and effectively to the application and environmental
concerns that impact the rotary kiln user today.
With the aid of computer modeling and computational fluid
dynamics (CFD), Coen can assess the performance characteristics
of new kiln applications or modifications such as fuel switching.
Coens programs predict temperature profile, flame shape
characteristics, and stack emissions.
COEN KILN BURNER SYSTEMS AND SERVICES
Since successful processing in a kiln involves much more than the
burner, Coens engineers are specialists in the design of complete
kiln burner systems including:
Flame safety systems
iScan2 Flame scanners
Gas or liquid fuel piping control modules
Spare parts
Start-up and commissioning services
