Establishment of these standards requires that an emission data base be developed for each source category. This data is used as a guide for the establishment of Performance Standards which will minimize air quality degradation and yet not be impossible to attain. The U.S. Environmental Protection Agency (EPA) retained Clayton Environmental Consultants, Inc., to visibly evaluate fugitive emissions emanating from the basic oxygen furnace (EOF) operations at Republic Steel in Cleveland, Ohio. Observations included fugitive emissions from the vessel operations (scrap charge, hot metal charge, oxygen blow, turndown, reblows, tapping, and deslagging), hot metal transfer, and the roof monitor. The field study was completed during the week of June 9, 1980. The results of this study will be used for supporting New Source Performance Standards for fugitive process emissions in the iron and steel industry. This study was commissioned as Project No. 80-BOF-8, Contract No. 68-02-2817, and Work Assignment 33. Project participants are listed in Appendix A. ------- 2.0 DISCUSSION OF RESULTS BASIC OXYGEN FURNACE Table 2.1 presents the Method 22 results of the fugitive emission readings taken during the various vessel operations. Emission rates are expressed as a frequency, the percent of time emissions are visible during the observation period. Each run constitutes one heat. A total of 13 heats were observed. The interval between two cycles(e.g., scrap charge and hot metal charge) was designated as interim. Generally, there was an interim between each cycle, however, only those interims with emissions are presented in the results. Emissions from the scrap charge ranged from 0 to 97- percent on the charging side and 0 to 86-percent on the tap side. Emissions during the hot metal charge ranged from 0 to 74-percent on the charging side and from 0 to 100-percent on the tap side. During turndown, fugitive emissions ranged from 0 to 100 percent on the charge side, and from 0 to 100 percent on the tap side. Tapping emissions ranged from 0 to 98-percent on the charge side and from 13 to 100-percent on the tap side. Deslagging resulted in fugitive emissions ranging from 27 to 100-percent on the charge side and from 0 to 100-percent on the tap side of the furnace. These wide emission frequency ranges substantiate the problems encountered during this study which are fully discussed in Section 3.0. - 2 - ------- TABLE 2.1 SUMMARY OF FUGITIVE EMISSIONS - VESSEL OPERATIONS 1 own Date Time Run No. a Cycle Furnace Number Emission Frequency, Percent Charge Side Obs. 1 Obs. 2 Tap Side Obs. 3 Obs. 4 6/9 1512 1 I 00 I 6/9 1605 2 a SC = HMC = 02 = TD = SC HMC INT 02 TD 02 1 TD TD TAP INT DS SC HMC INT 02 TD 1 02 TD TAP DS scrap charge hot metal charge oxygen blow turndown 48 14 0 <1 94 0 94 0 96 0 100 82 71 0 6 83 0 30 49 100 INT = TAP = DS = 49 16 0 <1 93 0 60 0 81 0 100 92 74 0 6 82 0 35 63 100 interim tapping deslagging 19 63 18 40 96 0 18 0 91 74 97 8 94 68 84 85 7 39 85 0 8 89 0 38 93 0 41 0 98 0 87 0 92 0 57 47 0 0 96 0 1 QQA j.ydu Date Time Sun No. Cycle Furnace Number Emission Frequency, Percent Charge Side Obs. 1 Obs. 2 Tap Side Obs. 3 Obs. 4 6/10 0820 3 SCI SC2 HMC INT 02 TD 02 TD TD 02 TD 02 TD INT TD 02 TD TAP INT 37 0 39 0 3 86 0 100 44 0 1 100 0 87 1 8 0 86 95 19 0 5 34 0 2 81 0 98 19 0 100 0 88 0 2 0 86 94 22 58 31 34 25 91 100 0 80 32 15 28 0 89 2 0 28 73 98 18 0 31 95 0 0 93 0 47 0 28 0 0 0 0 0 16 98 19 ------- TABLE 2.1 SUMMARY OF FUGITIVE EMISSIONS - VESSEL OPERATIONS (CONTINUED) 1980 Date Time Run No. Cycle Furnace Emission Frequency, Percent Charge Side Obs. 1 Obs. 2 Tap Side Obs. 3 Obs. 4 SC INT HMC INT 02 INT TD «/" TNO 02 INT TD INT TD INT TAP INT DS 97 0 0 0 1 0 95 22 76 0 50 83 19 0 0 4 0 79 88 0 0 0 2 0 99 69 0 41 100 49 4 0 0 0 99 39 77 74 28 92 83 76 68 46 42 68 92 71 0 94 100 0 74 86 69 70 0 92 0 88 58 87 39 68 97 74 0 63 78 100 94 1 QOA Date Run No. Cycle Furnace Emission Frequency, Percent Charge Side Obs. 1 Obs. 2 Tap Side Obs. 3 Obs. 4 6/10 1335 5 6/10 1513 6 SC HMC INT 02 TD 02 INT TD INT TAP INT DS SC INT HMC INT 02 INT TD INT 02 TD 1 TAP DS 86 0 0 13 88 71 2 17 91 0 39 22 100 31 0 0 0 8 0 2 45 0 0 38 61 86 86 0 0 12 88 36 15 95 0 42 13 100 32 0 0 0 9 0 34 0 0 32 62 86 13 84 30 83 100 85 0 91 7 96 61 51 11 37 90 72 68 13 6 2 78 - 67 0 69 95 38 83 100 93 0 81 12 100 58 100 23 86 100 100 60 0 30 0 97 6 59 30 •"•Turndown included two turndowns with an interim of rocking the furnace. ------- TABLE 2.1 SUMMARY OF FUGITIVE EMISSIONS - VESSEL OPERATIONS (CONTINUED) i cifln Date Run No. Cycle Furnace Emission Frequency, Percent Charge Side Obs. 1 Obs. 2 Tap Side Obs. 3 Obs. 4 1 QRO Date Run No. Cycle Furnace Emission Frequency, Percent Charge Side Obs. 1 Obs. 2 Tap Side Obs. 3 Obs. 4 6/11 0802 7 6/11 0847 8 SC INT HMC 022 TD 1 TD TAP INT DS SC HMP ill l\^ 02 TD INT TD 1 TD INT TAP INT DS 20 0 19 - 25 44 96 100 100 91 1 A -L'i 5 29 14 13 0 76 9 o n 80 24 0 30 - 24 38 98 0 100 86 5 21 9 32 0 58 46 O T 81 0 39 59 82 0 2 95 28 38 0 O Q o y 83 0 0 0 0 25 94 0 0 39 57 _ 0 0 97 50 31 0 Q O O j 86 0 0 0 0 47 100 0 0 6/11 1017 9 6/11 1323 10 6/12 0959 11 SC HMC 02 TD 02 INT TD INT TD TAP DS SC HMC INT 02 TD TD TAP DS HMC 02 TD TD TAP DS 8 7 <1 73 45 1 38 48 29 48 25 96 63 2 0 4 1 52 44 18 82 9 32 4 2 59 0 6 27 9 3 1 61 45 40 64 28 100 22 — 75 2 0 1 50 27 18 83 10 28 5 56 0 6 29 0 84 80 20 57 0 0 5 8 91 6 0 81 57 52 8 0 86 0 0 0 1 0 0 39 10 0 88 85 0 58 8 5 0 0 100 0 0 82 100 30 11 0 87 0 0 0 3 0 0 18 11 2Building filled with smoke, readings voided. ------- TABLE 2.1 SUMMARY OF FUGITIVE EMISSIONS - VESSEL OPERATIONS (CONTINUED) Date Run No. Cycle Furnace Emission Frequency, Percent Charge Side Obs. 1 Obs. 2 Tap Side Obs. 3 Obs. 4 6/12 1107 12 6/12 1324 13 HMC 02 TD TD 02 TD 02 TD TAP DS sc HMC 02 TD TD 02 2 TD 02 TD TAP DS 43 8 62 91 23 50 19 11 9 62 22 10 30 4 0 18 21 0 7 1 100 40 9 63 86 16 45 14 34 8 77 23 14 27 8 0 21 22 0 6 3 97 0 2 0 0 0 0 0 0 40 9 0 0 2 0 0 0 7 0 0 14 0 0 0 0 0 17 0 0 0 30 21 0 0 10 0 0 0 0 0 0 13 5 ------- ROOF MONITOR Method 9 Visible emission data were reduced using two methods. In Table 2.2, percent opacities were averaged for 24 consecutive readings, excluding any interferences. This method does not permit direct comparison of simultaneous observations. Table 2.3 presents the percent opacities in 6-minute averages, which includes all interferences, although averages were based only on the number of opacity readings taken during the set. Method 22 Results of the Method 22 roof monitor readings are presented in Table 2.4. Any corresponding interference times noted on the Method 9 data sheets were subtracted from each observer's accumulated observation time. Overall and unobscured averages for both Methods 9 and 22 are presented in Table 2.5. HOT METAL TRANSFER Table 2.6 presents the results of the data collected during hot metal transfer using Method 22. At this facility, several torpedo cars were emptied to fill one ladle; however, each pour of a single torpedo car constituted one emission test. Usually, the desulfuriza- tion material would be at the bottom of the ladle during the first pour; these pours were therefore called "desulf- urization runs". All other pours were hot metal transfers, - 7 - ------- TABLE 2.2.

"High inside winds. - 31 - ------- Wind seemed to have a marked effect on the emissions at this source. When the winds blew into the building, the emissions were higher inside than outside. At all other times the emission frequency was higher outside and negligible inside. Desulfurization emissions recorded at the inside location ranged from 0 to 3-percent, while emissions recorded outside ranged from 0 to 63- percent. Emissions for hot metal transfer observed inside ranged from 0 to 69-percent while emissions observed outside ranged from 0 to 93-percent. - 32 - ------- 3.0 OBSERVATION LOCATIONS AND EMISSION POINTS BASIC OXYGEN FURNACE The charge side observation location was in the public observation room opposite the furnaces. This room was about 60-feet above ground level and provided protection, safety, and good visibility. Tap side observations were made one floor above the EOF operations floor where observers viewed the top of the furnace. Since the tapping hood was located above the doors (back-side of the furnace), and emissions would most likely escape at this point, Mr. Roy Neulicht, EPA Technical Manager, decided that observations would be made at this location. Tests 1 through 10 were conducted from this position. Observations were also made of the tap side doors from the operations floor. Tests 11 through 13 were conducted at Location E. Emissions were considerably lower from this vantage point. Figure 3.1. depicts elevation and plan views of the EOF shop with respective observation loca- tions. Observations were made from Locations B & C for Furnace 1 and C & D for Furnace 2. Both observers moved from one side of the furnace to the other during a heat, therefore, only one side of the furnace could be viewed at a time. Thus, any emissions at the opposite side were not seen. The observers could not separate since only one radio was available. - 33 - ------- 4 k Teeming .Pot ELEVATION VIEW 7 Tapping Hood c \ Furnace Charging Hood 1 W121 Public Observation Room Public Observation Room PLAN VIEW Charging Isle (1st floor-operations floor)! © Ground Level Slag Dumping Area (Tap side locations one level above operations floor.) Figure 3.1. Basic oxygen furnace observation locations elevation and plan views. - 34 - ------- The area around the furnace was very dark and not an ideal observation location. The light meter barely registered 1 footcandle for the south side of Furnace 1 and 4 footcandles for the north side. The same problem was encountered at Furnace 2 except the darker side was the north side (1 footcandle). Light emissions were very difficult to see unless backlighted. Another problem was lack of maintenance on the furnace. Several missing plates around the top of Fur- nace No. 2 resulted in higher emission levels in that area. While observing the top of the furnace from the tap side, it was impossible to know whether the clocked emissions were those escaping only the tapping hood. It is very likely that emissions escaping both the primary and charging hood systems were included in the observations. HOT METAL TRANSFER The inside observation point for viewing the hot metal transfer shed was located approximately 20 feet southeast of the shed at ground level (Figure 3.2). it provided optimum viewing of the process at a safe distance. The outside readers were located about 40 feet due east of the shed. This location provided optimum viewing of the roof monitor and both ends of the shed. Since the wind was blowing from the north, it channeled through the shed, carrying emissions out the south end.

These emissions could have been from smoking torpedo cars rather than the transfer procedure. No distinction could be made, so all emissions exiting the shed were included during the observation period. ROOF MONITOR The three locations used for observing the roof monitor are presented in Figure 3.3. All took weather, sun angle, and view of the roof monitor into account. These locations were the only locations available to the observers. On Monday, June 9, 1980, the readings were made from a window on the fifth floor of the administration building, due east of the roof monitor. This location provided shelter for the readers during the frequent thunderstorms. The weather cleared on Tuesday, June 10, 1980, and all remaining observations were taken outdoors. The observations began each morning in a parking lot north- east of the roof monitor. In late afternoon the observers moved south of the administration building, due east of the monitor, because the sun angle was better. - 37 - ------- o EOF SHOP o 'Roof Monitor' N CO i Sun's position at the termina- tion of readings \ \ \ 6/9 fPM.

BASIC OXYGEN FURNACE The entire heat of the furnace was observed. A single heat, which was also considered one test run, included the scrap charge, hot metal charge, oxygen blow, turndown, any additional blows and turndowns, tapping, and deslagging. Two persons observed the charge side while two observed the tap side, simultaneously. All four observers used Method 22. Radio communications provided coordination between the observers. The desig- nated start and stop times for the above sequences were as follows: Scrap charge (charging door open) - two scrap buckets were used to charge the furnace. The scrap charge began from the tilt of the first bucket and ended when the second bucket returned to an upright position. Hot metal charge (charging door open) - from start of ladle tilt to its return to an upright position. 02 blow (charge door closed) - the sound of a depressurization discharge at the onset and completion of the blow. Observers on the tap side could also see the lance being lowered and raised. - 39 - ------- Turndown (charging door closed) - as the furnace tilts forward a bright glow appears at the upper edge of the charging doors, signifying the start of turndown. Turndown is completed when the glow disappears from the upper edge of the door as the furnace returns to its upright position. Tapping (charging door is either open or closed, depending on operator) - as the furnace tilts backwards, (toward tapping side), the bright glow of the metal can be seen at the lower edge of the door indicating the start of tapping. Completion is when the glow disappears as the furnace tilts upright. This procedure was used when tap observ- ations were made from the operation floor. When tap side observers viewed the top of the furnace and the charging door remained closed at the onset of tapping, all four observers coordinated to determine the starting point. Deslagging (charging door open) - from the start of furnace tilt to its return to an upright position. The furnace may be dumped 2 or 3 times before the entire deslagging sequence is completed. An entire heat usually lasted from 40 to 50 minutes. The heats were generally back to back, which would have extended the observation period to about two hours. This exceeds the recommended Method 22 observation time which specifies that the observer take a 5 to 10 minute break for every 15 or 20 minutes of observations. Since emissions were noted during the oxygen blow in the first three tests, the entire heat had to be observed. So as not to violate Method 22, alternate heats were read. A total of 13 heats were observed. HOT METAL TRANSFER Hot metal transfer observations were conducted from both indoor and outdoor locations with two observers at each location. - 40 - ------- The elapsed time (observation period) was measured from the time the hot metal began to flow into the ladle until it stopped. Radio communications provided coordina- tion between the observers. During the study, this facility conducted desulfuriza- tion during the hot metal transfer. The desulfurization material (Super-Sol) was dropped into the ladle prior to the hot metal addition. Therefore, the first pouring into the ladle was considered a desulfurization with subsequent pours considered hot metal transfers. A total of 11 hot metal transfers and 5 desulfurizations were observed. ROOF MONITOR Four observers were situated outside the EOF shop and viewed the same fugitive emissions emanating from the entire roof monitor. Two persons used Method 22, taking a 10-minute break between each 30-minute observation period. The other two persons read Method 9 for 1-hour intervals with 10-minute breaks. All four observers read from the same location and began simultaneously. - 41 - ------- |
