NR 439.098NR 439.098 Methods and procedures for parametric testing of NOx emissions pursuant to an acid rain program alternative NOx emission limitation. NR 439.098(1)(a)(a) An ultimate analysis of coal conducted according to ASTM D 3176-89, incorporated by reference in s. NR 484.10 (44). NR 439.098(1)(b)(b) A proximate analysis of coal conducted according to ASTM D 3172-89, incorporated by reference in s. NR 484.10 (41m). NR 439.098(1)(c)(c) A measurement of the coal mass flow rate to each individual burner using ASME Performance Test Code 4.2-1969 (1997) or ISO 9931 (1991), incorporated by reference in s. NR 484.11 (6) and (8). NR 439.098(2)(2) The owner or operator of an affected unit subject to the requirements of s. NR 409.065 may measure and record the actual NOx emission rate in accordance with the requirements of s. NR 409.065 while varying the following parameters where possible to determine their effects on the emissions of NOx from the affected boiler: NR 439.098(2)(b)(b) Settings of burners or coal and air nozzles, including tilt and yaw, or swirl. NR 439.098(2)(c)(c) For tangentially fired boilers, distribution of combustion air within the NOx emission control system. NR 439.098(2)(e)(e) Coal-to-primary air ratio (based on pound per hour) for each burner, the average coal-to-primary air ratio for all burners, and the deviations of individual burners’ coal-to-primary air ratios from the average value.

NR 439.098(3)(3) In performing the tests specified in sub. (1), the owner or operator shall begin the tests using the equipment settings for which the NOx emission control system was designed to meet the NOx emission rate guaranteed by the primary NOx emission control system vendor. These results constitute the baseline controlled condition. NR 439.098(4)(4) After establishing the baseline controlled condition under sub. (3), the owner or operator may do any of the following: NR 439.098(4)(a)(a) Change excess air levels ±5% from the baseline controlled condition to determine the effects on emissions of NOx, by providing a minimum of 3 readings.
