3. Approval of Minutes. The minutes from November 16, 2016 were approved with one addition: The volunteers for interlock terminology task groups were asked to email NFPA staff.

4. Staff Updates. Laura Moreno provided an overview of the Fall 2018 revision cycle schedule and the NFPA process. (attached)

5. Task Group Reports.

Chapter 5 Reorganization. John Eibl (chair), David Bohling, Scott Matz, Ted Jablkowski, and Kevin Carlisle. The task group reported that they submitted Public Input to reorganize sections 5.6 through 5.9 to make the layout and format consistent throughout the chapter. They also submitted several Public Inputs to the Fundamentals

Technical Committee to move general requirements to Chapter 4 and to provide new and revised definitions for various fuels. These Public Inputs were resolved. The Fundamentals Technical Committee proposed a task group to review all chapters for common requirements between the completion of this revision cycle and the start of the next, and noted that new definitions for fuel types can be added at the Second Draft stage if the Single Burner Boiler adds requirements to Chapter 5 that necessitate the new definitions.

6. Review of Public Inputs: NFPA 85 Chapter 5. The Technical Committee reviewed Public Inputs and developed First Revisions and Committee Inputs as necessary.

7. Review of Fundamentals Technical Committee actions. The committee members reviewed several items that were flagged by the Fundamentals Technical Committee for their review, and created First Revisions as necessary. John Eibl was tasked with reviewing First Revision 155, which adds overpressure protection requirements to Chapter 4.

The Technical Committee reviewed First Revision 108, which removes the exceptions to section 1.1.9.1. These requirements are essential for operation of these devices and they do not fit into Chapter 5 or Chapter 10. The exceptions need to be maintained, but could be rewritten so they are not in “exception” language if that is the intent of removing them. This should be brought to the attention of the Fundamentals Technical Committee and Correlating Committee.

The committee members also reviewed Committee Input 135, which was based off of a Public Input to include additional fuels in the scope of Chapter 5. At this time, the committee does not have language to add the additional fuels to Chapter 5, but will form a task group at the Second Draft meeting to review additional fuels. It was noted that use of other fuels is covered by the equivalency clause in section 1.5.

8. New Business. No additional new business was discussed.


of 61

9. Next Meeting. The Technical Committee agreed to hold the Second Draft meeting on January 16, 2017. A decision will be made after the Public Comment closing date to determine if an in-person meeting is necessary, but the tentative in-person meeting will be hosted by the Zurich Services Corporation outside of Chicago, Illinois.

10. Adjournment. The meeting was adjourned at 2:00 PM.

Public Comment No. 20-NFPA 85-2017 [ Global Input ]

The SBB Committee needs to review the use of "automatic (recycling)" and "automaticnonrecycling", and all the variations thereof (including "automatic (i.e. recycling)") forconsistency. If automatic means recycling, then automatic nonrecycling is conflicting. Itis preferred that the parenthesis not be used if they are not needed.The committee should also review 5.6.3.1. The cross references contained in thissection apply to auto- recycling but users are being directed there from the auto-nonrecycling paragraph.Similarly the committee should review the cross references in 5.6.4.1, which applies tomanual supervised systems.The committee should review 5.9.1.1 to see if the changes made to 5.7.1.2 are alsoappropriate.The committee should review the changes to 5.7.2(1) to see if the changes should bemade globally inChapter 5.

Public Comment No. 11-NFPA 85-2017 [ Section No. 5.4.2.3.1 ]

5.4.2.3.1* The two safety shutoff valves required in 5.4.2.3 shall have either an automatic vent valve with aposition interlock provided between the two safety shutoff valves or a listed valve-provingsystem.


The new requirement to add a position interlock to the vent valve is justified because the it is a safety issue if the vent valve fails to close when it should (leads to undetected low pressure to the burner and the venting of large amounts of gas) or fails to open when it should (leading to the inability for system to vent leakages from the upstream valve).

Public Comment No. 17-NFPA 85-2017 [ New Section after 5.4.5.5 ]

The proposed new material for 5.4.5.5 does not clearly override the requirement of4.13.2.1. One interpretation would be that both low airflow limits apply to SBBs.Therefore, the requirement would be to stay above the highest of the two low limits. TheSBB Committee should consider rewording 5.4.5.5 so that it clearly overrides thematerial in 4.13.2.1.

Committee Input No. 505-NFPA 85-2017 [ Section No. A.5.4.2.3 ]

This was a First Revision that has been modified or deleted as the result of FirstCorrelating Revision: FCR-31-NFPA 85-2017

A.5.4.2.3

Main burner gas supply. Special precautions are required in locating the vent pipe from theautomatic bleed valve so that heavier-than-air, vented gases do not accumulate in depressions or inconfined areas. An alternative to the automatic venting of heavier-than-air gases is to eliminate themain vent valve from between the two main safety shutoff valves use a valve proving system . SeeFigure A.5.4.2.3 for a typical main gas burner system arrangement.

CommitteeStatement:

Valve proving systems do not introduce any new hazards when used with LP gases. This isconsistent with the requirements in section 5.4.2.3. The language implied that leaking LPgases into the environment was a greater hazard than leaking gases into the combustionchamber, which was not the intent. The wording in the legend was revised to be consistent with the revised and new definitions forinterlock and trip.

CommitteeStatement:

The SBB Committee needs to review the use of "automatic (recycling)" and "automaticnonrecycling", and all the variations thereof (including "automatic (i.e. recycling)") forconsistency. If automatic means recycling, then automatic nonrecycling is conflicting. It ispreferred that the parenthesis not be used if they are not needed. The committee should also review 5.6.3.1. The cross references contained in this sectionapply to auto-recycling but users are being directed there from the auto-nonrecyclingparagraph. Similarly the committee should review the cross references in 5.6.4.1, which applies to manualsupervised systems. The committee should review 5.9.1.1 to see if the changes made to 5.7.1.2 are alsoappropriate. The committee should review the changes to 5.7.2(1) to see if the changes should be madeglobally in Chapter 5.

Class 2 igniters shall not be used to ignite the main fuel under uncontrolled or abnormal conditions.

4.7.7.5

Where Class 3 igniters are used, the igniter shall be turned off as a part of the burner light-off procedurewhen the time trial for ignition of the main burner has expired, to ensure that the main flame is notdependent on ignition support from the igniter.

4.7.7.6 *

Class 2 igniters shall not be used to extend the turndown range but shall be permitted to be used tosupport ignition under low-load or adverse operating conditions stabilize the main burner flame.

A.4.7.7.6 There are situations when a class 2 igniter can be returned to service to stabilize the main burnerflame, such as minor excursions from normal operating conditions. Temporary minor excursions include theintroduction of a slug of off-spec fuel, such as wet coal or noncombustibles. However, a class 2 ignitershould not be returned to service to avoid a load-based trip of a burner or mill, or if adding additional fuelcould lead to an unsafe operating condition .

4.10.1.2 Overpressure Protection.

4.10.1.2.1

Overpressure protection shall be provided in either of the following cases:

(1) When the supply pressure exceeds the design pressure rating of any downstream component

(2) When the failure of a single upstream line regulator or service pressure regulator results in a supplypressure exceeding the design pressure rating of any downstream component

4.10.1.2.2

Overpressure protection shall be provided by any one of the following:

(1) A series regulator in combination with a line regulator or service pressure regulator

(2) A monitoring regulator installed in combination with a line regulator or service pressure regulator

(3)

(4) An overpressure cutoff device, such as a slam-shut valve or a high-pressure switch in combination withan adequately rated shutoff valve

4.10.1.2.3

When a relief valve is used to comply with 4.10.1.2.1, the relief valve shall be a full-capacity relief type.

4.10.1.2.4

Token relief valves and internal token relief valves shall not be permitted to be used as the onlyoverpressure protection devices.

4.10.1.2.5* Set Point of the Overpressure Protection Device.

The overpressure protection device shall be set to provide a maximum downstream pressure as follows:

When the rated pressure of any component is less than 83 kPa (12 psig), the set point of the overpressureprotection device shall not exceed 150 percent of the rated pressure of the lowest rated component.

When the rated pressure of any component is equal to or greater than 83 kPa (12 psig) but less than 414kPa (60 psig), the set point of the overpressure protection device shall not exceed 41 kPa (6 psig) abovethe rated pressure of the lowest rated component.

When the rated pressure of any component is equal to or greater than 414 kPa (60 psig), the set point ofthe overpressure protection device shall not exceed 110 percent of the rated

(s) shall be set not higher than the design pressure of the lowest rated downstream component.

* A full-capacity pressure relief valve

A.4.10.1.2.2(3)

Upon upstream pressure regulation failure, a full-capacity pressure relief valve (versus token reliefvalves) will limit the downstream pressure. Token relief valves only provide minimum pressure reliefin cases where ambient temperatures increase the pressure inside the gas piping, which can occurduring shutdown periods, or relieve small increases of pressure due to high lockup pressures thatoccur during a shutdown.
