The EPA Title 1 NOx emission limits along with the corresponding OTR regulations are mandating coal-fired NOx emission levels below 0.15 lb/MBtu. For tangentially fired units, experience has shown that the technology is currently available to achieve these limits. The question for each unit owner-operator becomes; what is the most economical technology or combination of technologies to achieve the required results? This paper provides a brief overview of Combustion Engineering, Inc.'s (ABB C-E) latest NOx control technologies, both in-furnace and post-combustion, for tangential coal-fired steam generators. The paper further reviews options of both stand-alone and combined multiple technologies to achieve the most cost-effective NOx compliance, while maintaining the high levels of unit efficiency and performance that is required to by successful in their deregulated power industry. Current operational data of both in-furnace and SCR NOx reduction systems are presented, as well as the latest historical cost data for the systems.
