Introduction

Barr Engineering conducted nitrogen oxides (NOx) emissions concentration testing at Hibbing Taconite

Company located in Hibbing, Minnesota. The test was conducted as a voluntary effort to evaluate the

variability of NO x emissions as it relates to the normal operation of taconite production to establish a

predictive equation for NOx emissions. The test simultaneously measured the NOx emissions from the

four Line 2 Furnace Waste Gas Stacks for 168 hours.

A test plan was submitted to the Minnesota Pollution Control Agency (MPCA) dated August 29,

2007/0ctober 12, 2007. A copy ofthe test plan is provided in Appendix H. No pretest meeting was held

or MPCA approval letter granted due to the voluntary nature of the test.

Pete Rossmiller and Tom Leier of Barr Engineering performed the NOx testing. Andrea Hayden of

Hibbing Taconite Company coordinated the test team and facility operations. A representative of the

MPCA was not present to witness the tests. A list of project participants is provided in Appendix I. The

testing was performed from October 24- November 3,2007.

During the test, the Furnace Line 2 was operated using multiple operating conditions, which were within

standard operations. Process data was provided for each condition including fired pellet production rate

(long tons per hour), and firing temperatures. The process operating data is located in Appendix G.

The report provides results of the testing and does not address development of the NOx predictive

equations. Hibbing taconite will provide predictive equation information under separate cover.

Calculations and other' supporting documentation are located in the appendices.

Results Summary

On October 24,2007, testing started at Hibbing Taconite's Pellet Indurating Furnace Line 2 Stacks and

continued until November 3, 2007. The data that was collected was considered valid when all four

analyzers/systems were operating correctly and simultaneously. From October 24 - 31, unheated lines

transported the dry sample gas to the analyzer trailer for analysis, with moisture removal occurring at the

stack. Difficulties with moisture removal systems occurred due to cold temperatures. Significant down

time was experienced. The problem was corrected by using heat traced sample lines and moisture

removed in the analyzer trailer for the remainder of the testing. The delays are documented in the

Microsoft Excel file.

Hard copies of the data were not printed out due to the large volume of data. Instead, an electronic CD

copy is provided with this report that contains all of the test data and emission rate calculations. The data

that is provided is calculated by minute. The emission rate of NO x (IblIong ton) was calculated using the

average tonnage of the condition obtained with hourly averages. The firing temperatures provided are

the average of the condition based on hourly averages.

Hourly average ambient temperatures collected from the on-site meteorological station are provided in

AppendixD.

Process Description

Hibbing Taconite Company (HTC) mines iron are (magnetite) and produces taconite pellets that are

shipped to steel producers for processing in blast furnaces. The emission sources tested capture the waste

gases from the pellet indurating process.

Pelletizing Plant

Concentrate slurry flows to the thickener after which limestone is added for compression strength. The

moisture of the concentrate is reduced by disk filters and then mixed with bentonite and conveyed to

balling drums. After leaving the balling drum the green balls are discharged to a roll screen to control the

pellet size. The green balls are transferred to an oscillating conveyor and then to a roll conveyor for

additional removal of less than !4 inch material. The green balls are distributed evenly across the pallet

cars, prior to their entry to the pellet furnace. The pallet cars have a layer of fired pellets already on the

bottom and sides of the car called a hearth layer. The hearth layer allows for even airflow through the

pellet bed and acts as a buffer between the pallet cal' and the heat generated through the exothermic

conversion of magnetite to hematite.

There are three natural gas fired furnaces at HTC, Lines 1 and 2 (Phase I), and Line 3 (Phase II). The

straight grate furnaces at HTe have 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 climbs as the pellets

pass through each zone reaching a peak in the firing zone, after which 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 ail'

discharged from the two cooling zones is recirculated to the first zones of the furnace for drying and

preheating the green balls. Off gases from the furnaces are vented primarily through two ducts, the hood

exhaust that handles the drying and recirculated cooling gases, and the wind box exhaust that handles the

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

downstream fan, and then is combined with the hood exhaust steam in a common header. The exhaust

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

from individual stacks.

The testing was performed from ports meeting EPA Method 1 criteria (40 CFR Part 60, Appendix A).

An initial airflow using an S-type pitot was performed using EPA Method 2 criteria (40 CFR Part 60,

Appendix A). An S-type pitot tube was fixed at the point in the stack most representative of the average

velocity pressure. Differential pressure was read with a Dwyer Magnesense gauge at the stack and the

output signal was recorded in l-minute averages with a data logger. Calibrated type "K" thermocouples

were positioned in the stack with appropriate signal wire connected to the data logger for stack

temperature. Static pressure of the stacks was taken at the beginning of the test and that value was used

throughout. Barometric pressure was recorded at the stack test trailer every minute.

Calculations of volumetric airflow were made with l-minute data values for velocity pressure,

temperature, barometric pressure, oxygen, and carbon dioxide (for density). Stack gas moisture was

measured using approximation method (wet bulb-dry bulb technique) from EPA Method 4 criteria

(40 CFR Part 60, Appendix A) for each condition and applied to all calculations for that period. A single

static pressure for each stack was used for all calculations.

Nitrogen oxides, oxygen, and carbon dioxide concentrations were determined with modified EPA

Method 7E and 3A (40 CFR Part 60, Appendix A). Protocol I gas standards are used for daily

instrument calibration, system bias, and calibration drift checks. At least one system bias was performed

each day. Copies of the gas certification analysis can be found in Appendix F. A data logger was used to

collect the instrument output and calibration log. The data logger averages 60 l-second readings for

these I-minute averages. l-minute I-hour averages are provided in the electronic document. Detailed

calibration information is displayed in Appendix E and data logger output is displayed in Appendix C.

The system bias calibrations were performed at least once each day and these calibration results are used

to bias correct the raw NOx, 02, and C02 averages between the calibration times. A file can be found in

the CD jacket on the back of the front page which contains the Microsoft Excel file "60 minute file 11-

19-07(Values)."

Jeff,

I received this email from Barr. They are trying to put together the stack test report for the MPCA. What tonnage

range would we consider "high tons"?

ThanksAndrea

PART N. TEST METHODS

1. The following is a description ofthe test methods, number oftest runs, length of test runs, and sampling rate for

each pollutant

A EPA Method I for the location of sampling ports and points. One determination per test location.

B. EPA Method 2 (modified) single point velocity pressure. Continuous temperature will he recorded.

Moisture check will be recorded daily (wet bulb/dry bulb teclmique for moisture determination).

C. EPA Method 7E·- Modified for the determination of NO x concentration using a chemiluminescent analyzer

calibrated with EPA protocol 1 calibration gases of NO in nitrogen (High and Mid concentration for initial

calibration). Instrument precision and accuracy will be determined once per day using a zero gas and span

gas to establish any instrument drift. Data wiII be bias corrected using the pre and post zero/span test

results that precede and follow the stack gas NOx data. NOx emission data will be reported as I-minute

averages and l-hour averages in the following units: PPM (dry), lb/hour NOx, lb/long ton, and lb/mmbtu,

D. EPA Methods 7E-Modified, will be conducted as specified in 40 CFR Part 60, Appendix A and as

established in this test plan document.
