Introduction 

Barr Engineering Company performed engineering tests on the furnace scrubber stacks A-D (SVO 14-

SVOI7) at ArcelorMittal Minorca Mine Inc. facility located in Virginia, Minnesota. The purpose of 

the testing was to collect sulfur dioxide (S02) emission data. The tests were completed July 19-21, 

2011 in conjunction with compliance demonstration for oxides of nitrogen testing (NOx)' The NOx 

tests have been reported separately. 

Each furnace stack was tested independently for S02. Testing began on July 19,2011 at Stack A 

(SVOI4) and ended on Stack D (SVOI7) on July 21,2011. Each test series consisted of three onehour runs. 

Tom Kuchinski led the Barr test team. Jaime Baggenstoss and Adam Sersha of ArcelorMittal 

provided test coordination with facility operations. A list of project participants is provided in 

Appendix G.

Process Description 

ArcelorMittal mines taconite ore (magnetite) and produces iron pellets that are shipped to the 

company's blast furnace in Indiana. The wet scrubbers tested control the particulate matter emissions 

in the waste gases from the pellet indurating process. 

Concentrate slurry flows to a storage tank where limestone is added to make flux pellets. The 

concentrate is dewatered by vacuum disk filters, mixed with bentonite and conveyed to balling disks. 

Green balls produced on the balling disks are transferred to a roll conveyor for additional removal of 

over and undersize material. 

The green balls are distributed evenly across pallet cars, prior to entry into the pellet furnace. The 

pallet cars have a layer of fired pellets, called the hearth layer, on the bottom and sides of the car. 

The hearth layer acts as a buffer between the pallet car and the heat generated through the exothermic 

conversion of magnetite to hematite. 

There is one natural gas fired furnace at ArcelorMittal's taconite plant. The straight grate furnace has 

several distinct zones. The first two stages are updraft and downdraft drying zones. The next zones 

are the preheat zone and firing zone. The temperature increases as the pellets pass through each zone 

reaching a peak in the firing zone. The pellets enter the after-firing zone, where the conversion of 

magnetite to hematite is completed. The last two zones are cooling zones that allow the pellets to be 

discharged at a temperature of around 120 degrees Fahrenheit. 

Heated air discharged from the two cooling zones is recirculated to the drying, preheat and firing 

zones. Off-gases from the furnaces are vented primarily through two ducts, the hood exhaust that 

handles the drying and recirculated cooling gases, and the windbox exhaust, which handles the 

preheat, firing, and after-firing gases. The windbox exhaust flows through a multiclone, which 

protects the downstream fan, and then enters a common header shared with the hood exhaust stream. 

The exhaust gases are subsequently divided into four streams which lead to four venturi rod 

scrubbers and exhaust from individual stacks. 

Process throughput and control device data averaged by test run is summarized in the process 

operating forms located in Appendix F.

Sample port location and traverse point detail are provided in Figures 1-4. 

Volumetric airflow determinations were performed in accordance with EPA Method 2 using an Stype pitot tube and oil manometer. 

Oxygen and carbon dioxide was determined using EPA Method 3A with a Servomex 1440 02/C02 

analyzer 

Stack gas moisture content was determined by the performance of EPA Method 4. 

EP A Method 6C was used to determine the concentration of S02 with an API Model 100 EH ultraviolet florescence analyzer. A sample of the gas stream was drawn through a heated probe and filter 

and directed to a nafion dryer for moisture removal. The conditioned stack gas was transported to the 

analyzer in an unheated Teflon line. The instrument was calibrated using EPA Protocol 1 gases. 

Copies of calibration gas certifications are located in Appendix F. One-second instrument readings 

were averaged and recorded every 20 seconds in an electronic file using a data logger. Instrument 

output data from each test is located in Appendix C. 

The test methods referenced above are found in 40 CFR Part 60, Appendix A.
