M = 30%; SE = 33%; U = 19%; I = 19%) 5. Old Business A. Gas Line Purging Task Group - Members of the task group are: B. Baesel; R. Gallagher; T. Jablkowski; R. Kleen; D. Mason; and F. Switzer. The task group submitted recommendations to the committee to designate a single equipment isolation valve and identify it in annex A figures. The committee adopted these recommendations as First Revisions. NFPA Staff notes that the First Revision resulted in modifications only to fuel gas system diagrams. The Page 1 of 29
committee should review the First Revisions and determine if similar changes should be made to liquid and pulverized fuel system diagrams. B. Vent Valve Sizing NFPA Staff submitted a Code Fund Request to the Fire Protection Research Foundation. The project was released as a student project with an associated stipend. However, no volunteers were identified to perform the project. Therefore, it will be resubmitted for calendar year 2014. In addition, Mr. Zadiraka reported that he has interacted with industry participants who misunderstand the purpose of the vent valve, particularly in the SIS user groups. Mr. Zadiraka recommended that a definition or annex text be developed to clarify the purpose of the vent valve. C. Referenced Documents in Fundamentals Chapters. Mr. Switzer agreed to work with Mr. Mason to review the documents referenced in mandatory text in the Fundamentals chapters. In addition, the ASME Boiler and Pressure Vessel Code committee is working on a new section 7 on combustion systems. Sections 6 and 7 are recommended practices for maintenance of boilers, mainly focused on commercial/institutional sized boilers. NFPA Staff notes that Brian Moore is no longer participating in the NFPA Boiler Committees. NFPA Staff seeks a volunteer to continue monitoring ASME activities in this area. D. Requirement for burner management system to be limited to a single boiler or HRSG. NFPA Staff contacted API task group leader on draft recommended practice API 538 and learned that the final ballot was completed, but no timeline has been established for publication of the recommended practice. NFPA Staff will contact API staff and report to the committee. E. Glossary Update. The committee requested that NFPA submit a request to the NFPA Standards Council to include the NFPA Glossary of Terms into the boilerplate text in 3.1 of every NFPA Standard. NFPA Staff did not submit the request because it is not an issue reviewable by the Standards Council. NFPA Staff has submitted the request to the NFPA task group responsible for revising the NFPA Manual of Style. NFPA Staff will advise the committee of any action taken by NFPA. F. Recognition of NFPA 85 in Latin America. NFPA Staff agreed to work with Mr. Lasarte to increase awareness of NFPA 85, perhaps through NFPA Journal Latinoamericano. NFPA Staff contacted the NFPA International Department to identify additional resources, but no further action has been taken. Page 2 of 29
G. Fuel gas piping maintenance and purging task group. The committee established a task group to look at possible purging requirements downstream of the equipment isolation valve. The committee created Committee Input (CI) 125 to solicit public comments and support revision of NFPA 85. The task group scope is to recommend new minimum safety requirements for opening and recharging a fuel gas system for maintenance or inspection. The task group is asked to report back in the Second Draft meeting. Task group members are: B. Baesel (chair); T. Jablkowski; J. Kane; D. Mason; and A. Zadiraka. H. Interlock requirements task group. M. Polagye agreed to request that the Correlating Committee establish a task group to make recommendations regarding the interlock issues described by Mr. Dan Lee in Public Input 44. The Correlating Committee agreed to work as a committee on this issue, rather than establish a task group. The Correlating Committee will meet off-cycle following issuance of the 2015 edition to develop recommendations for the appropriate technical committees. 6. New Business A. Document Revision. Review BCS-FUN Public Comments and Correlating Committee Notes. (Attachment B). 7. Other Items? 8. Date/Location of Next Meeting. This concludes the committee work for the F2014 revision cycle. The next meeting will be scheduled as needed. 9. Adjournment. Page 3 of 29

The point on the fan head versus flow characteristic curve at which the fan is selected. This is the calculated operating point associated with the maximum continuous rating of the boiler or HRSG, plus the head and flow margins A fan s highest volumetric flow and static pressure rise capabilities for that fan s system resistance and inlet gas density. The current definition of Test Block Capability for fans does not provide a specific enough definition for the average user. This proposed new definition is meant to provide clarity to the users of the Code.

The point on the fan head versus flow characteristic curve at which the fan is selected. This is the calculated operating point associated with the maximum continuous rating of the boiler or HRSG, plus the head and flow margins. CC NOTE: The following CC Note No. 6 appeared in the First Draft Report as First Revision No. 77. The Fundamentals committee should reconsider the definition for Test Block Capability. The first sentence should be reviewed in the context of chapters 6 and 7, specifically casing design pressures (positive and negative transient design pressures). The second sentence appears to restrict the definition to boilers and HRSGs, therefore excluding the pulverizer supply air fan. In addition, the second sentence could be interpreted as a requirement.

7 of 109 11/18/2013 11:57 AM Public Comment No. 82-NFPA 85-2013 [ New Section after 4.1.4 ] TITLE OF NEW CONTENT: 4.1.4.1 Single burner boilers listed and approved for unattended operation shall not require a process hazard analysis. Single burner boilers desinged and listed for unattended operation have been proven by operating history to have sufficient controls and safety interlocks to prevent unsafe operation that result in fires or explosions. When such boilers are acceptable to the authority having jurisdiction, a PHA should not have too be performed before such a boiler is installed abd operated. The submitter would have ideally liked to have added this paragraph in Chapter 5 for single burner boiles, but could not find an acceptable spot within that chapter and therefore elected to place it after the paragraph in Chapter 4 that requires a PHA for unattended boilers.

Unattended operation, no operator at the operating location(s), or operation of the plant from an off-site operating location shall be approved and shall require a process hazard analysis (PHA). CC NOTE: The following CC Note No. 7 appeared in the First Draft Report as First Revision No. 85 and 86 and also related Public Input No. 136 and 76. The Fundamentals committee should reconsider moving this requirement from chapter 6 to chapter 4 because of the broad implications. For example, a common application of single burner boilers is unattended operation. Members of the subject committees for chapters 5 through 10 should specifically review this item to provide public comments to the Fundamentals or subject chapter as appropriate.

1 of 109 11/18/2013 11:57 AM Public Comment No. 73-NFPA 85-2013 [ Section No. 4.10.3.1 ] 4.10.3.1 * The requirements in Section 4.10.3 shall apply to flue gas path auxiliary systems that inject fuel, oxidizer, or combustible reagent into the boiler enclosure or flue gas path when in operation. A.4.10.3.1 Flue gas path auxiliary systems shall be that inject fuel, oxidizer, or combustible reagent into a boiler enclosure or flue gas path can include but are not limited to sulfur burner systems, ammonia injection systems, activated carbon injection systems, soot blowing or soot cleaning systems, and fired reheater systems. Having a requirement that defines, and limits, what a flue gas path auxiliary system is doesn't make sense. And in the case of soot blowing system, many/most don't use fuel, oxidizer, or combustible reagent and these requirements don't apply. The existing wording could create confusion as to whether or not that is the case. Also, if there are or will be other systems that should meet the requirements of this section that are not in the "list", that could be construed as the requirements not applying to them. The proposed revised wording and Annex material addresses these concerns.

The term "boiler or HRSG" would not include pulverized fuel systems. The term "boiler or combustion system" should define the intended scope more appropriately. The term "boiler" was removed from the last line for the same reason.
