Title: Title IV - Phase II NO{sub x} compliance strategy for Minnesota Power

Minnesota Power`s (MP) coal-fired generation system is comprised of Title IV-Phase II boilers. Although Phase II boilers are not required to meet emission limits until January 1, 2000, the standards may be more stringent than Phase I NO{sub x} limits. MP is investigating the merits of foregoing system averaging under a yet to be determined Phase II rule, and pursuing an early election option with current Phase I NO{sub x} limits. Boswell Station is comprised of two Riley Stoker face-fired boilers of nominally 74 gross MW generation that went on-line in 1958-60, and two CE tangentially-fired boilers of 372 MW (1973 operation) and 565 MW (1980 operation). All units are balanced draft. Carnot conducted baseline characterizations of MP`s four units at the Boswell Station as the first step in an assessment of the best course of action. This paper will present the baseline data collected and the approach taken in preparing the NO{sub x} compliance strategy for all boilers within the MP system. The approach takes into accounted the projected system load profile and capacity factors for individual units and the cost effectiveness and system flexibility inherent with NO{sub x} compliance achieved on an individual unit basis or with systemmore » averaging.« less
