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

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
