Coen: A Standard of ExcellenceBy applying the latest technology, Coen's duct burners deliver the lowest combined emissions available today. This includes oxides of nitrogen (NOx), carbon monoxide (CO), VOC's and particulate matter (PM10 ). Today's regulatory environment demands that the best technology be applied to the supplementary firing of turbine exhaust gas (TEG) to meet stringent emissions requirements. This legitimate concern to maintain air quality has made emissions a significant decision consideration, from permit application to performance testing. Coen provides the solution to meet all of today's air quality regulations. With Coen you can be confident that we will deliver dependable results and superior service. Not only do our burner systems set the industry's standard of excellence year after year, but we provide a thoroughly engineered approach, using only advanced designs to deliver maximum performance. Experience Delivers PerformanceThe first Coen duct burner for supplementary firing of gas turbine exhaust was commissioned in 1968. The years to follow marked innovation in design and performance.
Over the years Coen has been involved in over 600 installations on gas turbines with greater than 10 MW and has provided duct burners for over 850 units worldwide. Whether serving small, medium or large cogeneration, combined cycle, or the Independent Power Producers ( IPP) market requirements, Coen duct burners have a proven record for minimum emissions, maximum flexibility and low maintenance. That's performance! Rugged Design Delivers PerformanceCoen duct burners provide stable combustion with the latest generation of turbines at TEG oxygen levels less than 11% by volume, wet. Heavy duty high alloy burner castings and rugged systems components assure reliability. Turndown range is over 20:1 firing gas, 5:1 firing oil without staging burners on and off. These duct burners are available in heat release ranges of more than 700 million Btu/hr. A factory packaged and tested piping module and a microprocessor based flame safeguard system are included with the duct burner.
Emission ConcernsEmissions are basically unwanted combustion products. The ideal hydrocarbon combustion products, water vapor and carbon dioxide, exist commonly in nature and have no ill effects on the environment. Other than the current concern for build-up of carbon dioxide in the atmosphere, these products are generally considered to be harmless. The emission products of concern are NOx, CO, VOC, SOx and PM. Coen duct burners efficiently reduce emission products to their lowest levels. We pursue and implement the latest technology that provides economic and environmental benefits. Also, we are committed to provide the latest in combustion and emission control technology to meet the needs of IPP's and the cogeneration industry. Research, Development and TestingCoen's commitment to ongoing research and development assures that the company can respond quickly and effectively to the changing regulatory environment that impacts the combustion industry today. With the aid of computational fluid dynamics (CFD) and other flow/combustion software programs, Coen can assess the thermal, chemical and physical performance characteristics of each new duct burner design. This helps to minimize the number of physical tests and trials, allowing for shorter lead times between design and production. A state-of-the-art test facility allows new Coen duct burner designs to be tested and evaluated to assure predictable, superior performance.
