Recent Progress With The Intelligent Emission Control System Abstract Felix Heimes, Lockheed Martin Control Systems l Jack Dunphy, Lockheed Martin Control Systems John Smigelski, New York State Electric and Gas Thomas O'Meara, New York State Electric and Gas The Intelligent Emission Control System (InEC TM ) is a powerful tool that enables power plant operators to meet emissions requirements and maintain optimum performance of the combustion system. The InEC TM system uses advanced computational intelligence techniques to create customized emission models for a particular boiler. It also utilizes a performance calculation based on the unit's controllable losses. An optimization algorithm combines information from the emissions and performance models to recommend the optimum control settings to the operator. The InEC TM system has been installed in two plants: a 680 megawatt wall fired boiler and an 80 megawatt tangentially fired boiler. This paper will discuss the application of the InEC TM system for these two boilers and the results of these applications. Introduction The operation of an electric generating facility is becoming increasingly more complex. There are many demands placed on fossil fuel (e.g. coal) generating unit personnel. These demands include: • Meeting Clean Air Act emissions requirements • Reducing operating costs • Maintaining safe unit operations • Producing marketable fly ash • Maintaining high levels of generating unit availability • Cycling the unit through the load range These demands place, even the experienced operator, in a very challenging situation of conflicting operating objectives. In addition, reductions in work force has put more responsibility on a reduced and less experienced staff. These conflicting operating objectives provide new challenges to our industry at a critical time. A new approach must be found to address these challenges while providing the flexibility to adapt to the ever changing environment of the future. New York State Electric and Gas (NYSEG) and Lockheed Martin Control Systems (LMCS) have teamed together to develop an advanced NOx control and performance optimization system called the Intelligent -1- |
