Description
Summary:The ability to achieve sub-5 ppm NOx in situ should be music to the ears of many cost-conscious owners and developers of gas turbine plants. At many locations with stringent air-quality limits, factory-installed dry low-NOx (DLN) combustors such as GE's - which can get down to 9 ppm - no longer cut the mustard. An expensive selective catalytic reduction (SCR) system, and perhaps a CO catalyst as well, also must be added downstream of the turbine to reduce its NOx emissions into the 2.5-ppm range in some locations. The availability of the LEC III as a plug-and-play replacement for an OEM's combustor means that such expensive additions now can be avoided. At first glance, the "trick" responsible for the LEC III's stellar performance seems obvious and simple enough: more-thorough mixing of fuel and air. However, as in most engineering breakthroughs, the devil is in the details.
