# Introduction

BarrEngineeringCompany conducted sulfurdioxide (SO}) emissions testing atArcelorMittal

Minorca Mine Inc. located in Virginia, Minnesota. The testingwas performed to evaluate SO}

emissions from four induratingfurnace stacks as it relatesto the normal operation oftaconite production. Thetests consecutively measuredthe SO} concentration and volumetric air flow rates
from the four induratingfurnace waste gas stacks. The stacks, A-D, comprise emissions unit EU026,

which is located in Building007 PelletPlant.

Testingwas performed concurrentwith nitrogen dioxide (NOx) tests required bythe facility'S Title V permit.

Duringthe test, the induratingfurnace was operated undernormal operatingconditions. The indurating furnace can typically process between 310-350 longtons perhr. The process operating
data, heat inputdata, and fuel usage data are provided in AppendixF.

Testingwas performed byTom Kuchinski and Tom LeierofBarrEngineeringfrom March 31 to April 2, 2009.Jaime Baggenstoss and Jon Maki ofArceiorMitta1 coordinated thetestteam and facility operations. A list ofprojectparticipants is provided in Appendix G.

# Results

Testing ofArcelorMittal'spelletinduratingfurnace waste gas stackstook placebetween March 31
and April 2, 2009. Thetestresults are provided in Tables 1-3. Table 1includes atotal airflow for the
four stacks, airflow-weighted average concentration, total emissions rate and an aggregate emissions
factor.

On March 31 there was a process upset duringthetest on StackA. Run 3 was delayed until the following day. Therewere difficulties withthe flexible line used for the moisturetrain due to freezing temperatures affectingruns 1and 2. Aftercorrectingthe problem, a 30-minute moisture run

was conducted duringthe secondhalfofrune 2, yielding a result in line with the expected saturated

gas stream moisture content. This moisture contentwas used for run 2, and the average ofruns 2 and
3 was substitutedfor run 1.

Process data are summarized in Table 5 and detailed process data are provided in AppendixF.

determined to be non-stratified, and the samplingprobewas positioned in the centroid ofthe stack
forthe remainderofeach test. Therecorded Method 1criteria are listed in thetable below. Figures 1 through 4 provide schematic details ofthe sample port locations and traverse points.
