1 ROTARY KILN COMBUSTION SYSTEMS

2 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 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. COEN FOR 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 World-Class Domestic and International Manufacturing Facilities Low emissions kiln burner on shop floor A Koch Chemical Technology Group Company

3 Features of the Coen Kiln Burner Pulverized Fuel Inlet (Petroleum Coke, Coal, etc.) 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 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 Oil Inlet Dual Zone Primary Air Inlet 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. 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. 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 ½ thick spuncast with no welds or seams. MULTIFUEL CAPABILITY: The Coen burner is designed to handle gas and oil firing Dual Air Zones Refractory coating for high temperature applications is available. simultaneously or in combination with solid fuels such as coal, petroleum coke, or wood. Natural Gas Inlet Pilot Gas Inlet ADJUSTABLE DUAL ZONE GAS BURNER: For precise flame shape control, Coen has developed the dual zone gas burner. Adjusting the fuel split between these Gas Annulus and Core Adjustment Discharge Support Ring 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 High Alloy Spuncast Dual Zone Gas Nozzle 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. Fyr Lyter Pilot Isokinetic Spinner Oil Atomizer

4 CFD Model to Achieve Superior Performance Temperature distribution and flame shape characteristics 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. Coen s 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, Coen s 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 CONTACT US TODAY AND LET COEN DESIGN A SYSTEM TO MEET YOUR NEEDS.
