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.
