Lowest cost integrated NO{sub x} solutions for Title 1 and ozone transport rule compliance

Deregulation of the power industry and tightening of NO{sub x} regulations are creating challenges for electric utilities. Just as utilities are striving to drive down costs, further NO{sub x} control requirements will result in increased capital and operating expenditures. A range of combustion technologies and post-combustion systems are available, and the key will be the optimization of their use to minimize costs. This paper briefly reviews the current regulatory status as well as the range of burner, overfire air port and SCR deNO{sub x} systems available. The paper concludes with the results from a B and W economic model used to optimize NO{sub x} control options on a plant-specific basis.
