6 *Participated by teleconference 1. Call to Order. Michael Walz, Chair, called the meeting to order at 8:06 AM on February 7 and welcomed attendees to the meeting. 2. Introductions. Attendees introduced themselves and identified their affiliation. 3. Approval of Minutes. The minutes from March 16, 2016 were approved without revision. 4. Staff Updates. Laura Moreno provided an overview of the Fall 2018 revision cycle schedule and the NFPA process. (attached) 5. Review of Public Inputs: NFPA 85 Chapter 6. The Technical Committee reviewed Public Inputs and developed First Revisions and Committee Inputs as necessary. A task group on interlock functional tests was formed to review testing requirements and frequency for functional tests (see First Revision 163 (section ), First Revision 169 ( ) and First Revision 174 ( )). The task group members are David King (Chair), Jimmie Schexnayder, James Franks, Franklin Switzer, and Marc Cropp. The task group on Plasma Arc Igniters presented their work (attached) in conjunction with several of the Public Inputs. The group was asked to continue their work by developing annex material based on the public input language to provide guidance on how integrated burner-igniter systems should be used. The task group also intends to address the starting sequence and supervisory controls for this technology (see Committee Inputs 307, 309, and 310). There were additional volunteers for the group; for the complete list see Item Review of Fundamentals Technical Committee actions. The Technical Committee reviewed several items that were flagged by the Fundamentals Technical Committee for their review, and created Committee Inputs as necessary. Bill Smith and Skip Yates were tasked with reviewing igniter classification tests proposed by Committee Input 142, and John Eibl was tasked with reviewing Committee Input 322 and First Revision 155, which would remove overpressure protection requirements from in favor of those added to Chapter Task Group Reports. Design Pressures. B. Smith (chair), D. Evely, J. Frazier, D. King, J. Lehman, H. Wong, and A. Zadiraka. Dale Evely submitted several Public Inputs to change test block to maximum head throughout the document, but after discussion these were resolved without revision by the Multiple Burner Boiler committee. The task group was dissolved with the committee s thanks. Page 6 of 81

7 Plasma Arc Igniters. S. Yates (chair), B. Smith, K. Gamble, S. Matz, E. Lightbourn, M. Kinoshita, J. Eibl, Denise Beach, Frank Bennett, and Carlos Santos. This task group will continue their work with a revised scope (see Item 5). Valve Leak Testing. S. Matz, C. Schmidt, and F. Switzer. Based on committee discussion that the tightness test and the operational leak test of the header do not serve the same purpose and both sets of requirements need to be retained in the code, no changes were recommended. The task group was dissolved with the committee s thanks. Boiler Enclosure Definition/Purge Times. J. Franks (chair), D. King, J. O Rourke, and J. Parker. Public Input was submitted and discussed but the Technical Committee ultimately did not make any revisions to purge time calculation methods. The task group was dissolved with the committee s thanks. 8. New Business. No additional new business was discussed. 9. Next Meeting. The Technical Committee agreed to hold the Second Draft meeting on January 23-24, 2018 in Phoenix, AZ or New Orleans, LA. 10. Adjournment. The meeting was adjourned at 3:25 PM on February 8.

26 National Fire Protection Association Report 11 of 16 Second Revision No. 708-NFPA [ Section No ] Overpressure Protection 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 supply pressure exceeding the design pressure rating of any downstream component D r Su aft bj R ec ev t t isi o on Ba s llo t 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)* A full-capacity pressure relief valve A (3) Upon upstream pressure regulation failure, a full-capacity pressure relief valve (versus token relief valves) will limit the downstream pressure. Token relief valves only provide minimum pressure relief in cases where ambient temperatures increase the pressure inside the gas piping, which can occur during shutdown periods, or relieve small increases of pressure due to high lockup pressures that occur during a shutdown. (4) An overpressure cutoff device, such as a slam-shut valve or a high-pressure switch in combination with an adequately rated shutoff valve When a relief valve is used to comply with , the relief valve shall be a full-capacity relief type Token relief valves and internal token relief valves shall not be permitted to be used as the only overpressure protection devices * 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 overpressure protection 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 414 kpa (60 psig), the set point of the overpressure protection device shall not exceed 41 kpa (6 psig) above the 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 of the 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.

39 12/18/2017 National Fire Protection Association Report Public Comment No. 38-NFPA [ Section No ] * Before main fuel firing and following a master fuel trip, FD fans shall be tripped if the furnace pressure exceeds the maximum pressure value recommended by the manufacturer. Exception: For units where the maximum head of the FD fans is less than the continous design pressure of the boiler enclosure, b efore main fuel firing and following a five minute period following a master fuel trip (furnace postpurge), FD fans shall be tripped if the furnace pressure exceeds the maximum pressure value recommended by the manufacturer. Statement of Problem and Substantiation for Public Comment Revisions made in the First draft were completed without reference to any actual operational experience or events that would dictate a need to revise the code. The text deleted from the paragraph has been a part of the NFPA 85 document since the development of the NFPA 85G standard published in Removal of the text from the code does not address the basic desire of completing a post trip purge prior to shutting down FD fans. For balanced draft units and in cases where the FD fan(s) are tripped due to a high furnace pressure condition, the ID fan will remain in controlled operation but airflow through the boiler and associated air and flue gas duct work will be significantly reduced.

40 12/18/2017 National Fire Protection Association Report Public Comment No. 36-NFPA [ New Section after K.3 ] X.1 Concentrated Flame Igniters General Considerations and Definitions X1.1 New igniter technologies, to be referred to as Concentrated Flame (CF) Igniters, have been developed which can reduce, or even eliminate, the consumption of igniter Fuel Oil or Fuel Gas used in coal fired boiler warm up, mill group ignition, and low load support. A burner with an integral ignitor assembly specifically designed and fabricated for the initial combustion to take place within the burner barrel as opposed to outside the burner in the furnace cavity, as is done for traditional igniters, is an example of this new technology. For CF igniters, with the igniter in service, combustion may extend into the furnace cavity, however the initial point of combustion is designed to be inside the burner. These systems can be beneficial for at least the following reasons 1) the initial combustion is controlled within the burner barrel, where there is a high level of contact between the ignition source and the Primary Air stream, and 2) in the case of the plasma based form, the very high boundary temperature (much higher than adiabatic flame temperature of coal, oil or gas) promotes fracturing and devolatilization of the coal particles, leading to prompt ignition. CF igniters may take multiple forms based on the heat energy source by which the coal stream is ignited. The most common form of CF igniters uses an ionic plasma gas to ignite the coal and primary air mixture. However, other designs may use Fuel Oil, and less commonly Fuel Gas for the initial ignition. Generally, but not universally, only a subset of the Primary Air/Fuel stream is initially ignited. Some designs utilize successive concentric annular combustion zones inside the burner barrel to stage the mixing of the Primary Air/Fuel stream to control the ignition of the remaining portions of the Primary Air/Fuel stream. When the igniter is no longer required to be in service, the igniter is de-energized, and the ignition point quickly propagates to the front of the barrel tip as in traditional burner operation. CF igniters have been deployed on both wall and tangentially fired furnaces on a wide variety of coal ranks. The plasma form of CF igniters is designed to require no support fuel consumption. The Fuel Oil and Fuel Gas forms claim reduced consumption of the igniter fuel compared to a conventional Class 1 igniter. For both forms with a boiler in a cold state separate equipment and energy source to heat the primary air to the required temperatures are required as energy cannot be recovered from the cold flue gas. X1.2 Side Sectional Views of Common Forms of Concentrated Flame Igniters Figure AX.X.X: Axial Configuration Figure A.X.X Tangential Configuration X1.3 Plasma Definition. Plasma is a gaseous mixture of negatively charged electrons and highly charged positive ions which can conduct large and sustained electric current and generates very high temperatures. In common forms of plasma igniters, the plasma is generated when a strong electric potential is applied between anode and cathode elements. Plasmas respond to electromagnetic forces and the plasma gas may be controlled using magnetic induction coils. X.2 Technology Overview The CF igniter is designed to be an integral part of the burner barrel, while a conventional igniter in some furnace designs may be physically independent of the burner. Because of its integral design feature, a CF igniter would not properly function in a different burner barrel, and a conventional igniter would not properly function in a burner barrel designed for a CF igniter. The technology can be compared with conventional coal burner igniters as follows. For a conventional igniter: 50/54 Page 40 of 81
