Public Input No. 215-NFPA 85-2017 [ Global Input ]

All technical committees should review the proposed changes to the definitions of "trip," "interlock,"and "permissive," as well as the recommendations below:

Draft Definitions and Guidelines developed by the

NFPA 85 Correlating Committee and Fundamentals Committee

Draft definitions for interlock, permissive, and trip.

· Interlock: A function which prevents, limits, stops, or initiates the operation of equipment or a subsequentfunction.

o Annex language: An interlock can consist of a sensing function, a control function, and anoutput or a final control element. The interlock can be accomplished with the use of anycombination of electrical devices, mechanical devices, or logic.

· Permissive: An interlock that functions only to allow initiation of the operation of equipment or asubsequent function

· Trip: An interlock that shuts down equipment when a predefined set of conditions exists.

It was decided that permissive and trip should be subdefinitions under interlock, but they should also appear inalphabetical order with a reference back to the interlock section, similar to what is done for “coal” in 3.3.30.

Recommendations for other Chapters. The following recommendations have been developed for the use of“interlock” and related terms throughout the code:

· “Safety device”, “protective device”, “interlock device” and “safety interlock device” appear to besynonymous. The Fundamentals Committee suggests using "interlocks" or "interlocks and associated devices"as appropriate.

· “Safety function” is similar to the new definition of an interlock. The Fundamentals Committee suggestsusing the term interlock.

· “Master fuel trip device” is not defined in Chapter 3, and is only used in Chapter 7 and its Annex. If this isintentionally different from a master fuel trip relay, it should be defined in Chapter 3. Otherwise, it should bereplaced with “master fuel trip relay”.

· “Safety shutdown” is only used in Chapters 3, 4, and 5, and the Annex to Chapters 5 and 7. Forconsistency throughout the document, the Fundamentals Committee recommends replacement with “trip” or“master fuel trip”, as appropriate. The Fundamentals Committee will be removing the term from Chapters 3 and4.

· “Emergency shutdown” is used in Chapters 4, 6, 7, 8, and 10, and the Annex to Chapters 4, 6, and 7, aswell as Annex B. This appears to be the same as a safety shutdown, so the Committee recommendsreplacement with “trip” or “master fuel trip” as in the comment above. The Fundamentals Committee will beremoving the term from Chapter 4.

· “Abnormal shutdown” is only used twice, both times in Chapter 6. This appears to be synonymous with“trip” and for consistency, that term should be substituted.

· “Interlock system” is used in Chapters 4, 5, 6, 7, 8, and 9. The Fundamentals Committee will be removingthe term from Chapter 4 by replacing it with “interlocks” and recommends replacement in other chapters.


To comply with the recommendations of the Fundamentals TC.

1.1.4 (Current Text):

Chapter 5 covers single burner boilers that fire the following fuels:

(1) Fuel gas as defined in 3.3.64.

(2)

(3) Fuel oil as defined in 3.3.63.3

(4) Fuel gas and fuel oil that are fired simultaneously for fuel transfer

(5) Fuel gas and fuel oil that are fired simultaneously and continuously

Revise as follows:

1.1.4 Chapter 5, Single Burner Boilers, covers single burner boilers that fire the following fuels:

(1) Natural gas as defined in 3.3.71.10.

(2)*Other commercial grade fuel gases having a calorific value and characteristics similar to natural gas

(3) Fuel oil of Grades 2, 4, 5, or 6

(4) Gas and oil that are fired simultaneously for fuel transfer

(5) Gas and oil that are fired simultaneously and continuously

(6) Non-commercial grade fuel gases


The SBB Committee wishes to amend the scope statement to define and address the use of non-commercial fuels in its chapter. Non-commercial fuels such as landfill gas, process off-gases, etc. are used in increasing single burner applications. The Technical Committee will continue to add material to address specific concerns and requirements when using these types of fuels.

Public Input No. 23-NFPA 85-2016 [ Section No. 1.1.9.1 ]

1.1.9.1

Where solid fuel is fired simultaneously with other fuels (e.g., a solid fuel stoker fired in combination withfuel gas, fuel oil, or pulverized auxiliary fuel), additional controls and interlocks shall include those coveredin Chapters 5, 6, and 9.

Exception No. 1: The purge requirements of Chapters 5 and 6 shall not be required when the stoker isfiring and the boiler is on-line. In those cases, if no cooling air is being provided to the auxiliary burners, apurge of their associated air supply ducts shall be provided.

Exception No. 2: Where fuel oil or fuel gas is fired in a supervised manual system in accordance withChapter 5 , the excessive steam pressure interlock shall not be required.


The FUN TC decided that the STO and SBB TC's should address these exceptions in their respective chapters.

PINo.2JUSTIFICATION:Paragraph 3.3.73.1 uses the phrase “credible combination of burner inputs” in the definition of a Class 1 igniter. The phrase is vague, and is not defined in Section 3. The igniter definition does constrain those burner inputs to apply to both light‐off conditions and operating conditions. This PI offers supplemental information to be placed in the Annex to help users develop their testing protocol (See 4.7.7.1) to carry out the required testing, and to explore operating limits of the igniter to perform as required. The overall intent of PI1 and PI2 is to tie together the igniter definition and classification (3.3.73), and required igniter testing (4.7.7.1).

TITLE OF NEW CONTENTType your content here ...NEW 3.3.73.3* Class 2 Special Igniter: An integrated burner-igniter system thatutilizes a staged ignition system within the burner. The primary igniter shall utilize oil or natural gas, or aplasma arc to ignite a portion of the main fuel stream which then provides ignition to the remainder of htefuel stream. It is also used to support ignition under low load conditions where the main flame is proven.


Problem statement: Existing igniter systems are typically independent of the burner they are intended to ignite. A new technology is available whereby a portion of the main fuel stream is ignited internally in the burner barrel using oil, gas or plasma. The technology necessitates adjustments in operating methodology for proper function. A task group comprised of members from BCS-MBB has studied this technology. This paragraph, in conjunction with other proposed paragraphs, addresses that new technology.SUBSTANTIATION: The proposed code revisions will provide minimum safety requirements that can enable US coal fired power plants to respond to real time market conditions in a timely manner. The technology is desirable as it reduces or eliminates the amount of premium fuel used to start a boiler.The technology has been successfully applied outside the US with installations in over 1,000 coal fired boilers in both the plasma and oil igniter form, and is available from multiple suppliers/manufacturers. These installations have helped determine the suitability of the technology and gives confidence in its safety potential.

* Integrated Burner-Igniter System: An igniter integral to a staged ignition burner assembly,whereby a portion of the main fuel stream is raised to a temperature above its auto-ignitiontemperatureand this heated fuel then ignites the remainder of the main fuel stream as it enters thefurnace.


Problem Statement

Existing igniter systems are typically independent of the burner they are intended to ignite. A new technology is available whereby a portion of the main fuel stream is ignited internally in the burner barrel using oil, gas or plasma. The technology necessitates adjustments in operations methodology for proper function. A task group comprised of members from BCS-MBB has studied this technology. This paragraph, in conjunction with other proposed paragraphs, addresses that new technology.

Substantiation

The proposed code revision will provide minimum safety requirements of a new technology that can enable US coal fired power plants to respond to real time market conditions in a timely manner. The technology is desirable because it reduces, or eliminates, the amount of premium support fuel used to warm up a boiler and to bring on successive mill groups.

The technology has been successfully applied outside the US with installations in over 1,000 coal fired boilers in both the plasma and oil igniter form; and is available from multiple suppliers/manufacturers. These installations have helped determine the suitability of the technology for US plants and give confidence in its safety potential. To enhance user safety the system is being proposed as a new igniter classification (a “Special” derivative of the existing Class II) which requires the usage to be under defined conditions only.

The key distinguishing characteristic between the igniter classes in the NFPA 85 code is the difference in igniter ability to tolerate process variations. Based on the igniter ability to function under difficult conditions, the implementation and the privileges of the igniter class vary. Whereas Class I can be used under “all credible” conditions (3.3.73.1), Class II can be used under “prescribed” (3.3.73.2) light off conditions only.

The restriction to prescribed conditions is also required due to the difficulty in igniter flame proving in some of these applications for the plasma igniters form. The location of the igniter flame inside the burner barrel, where it cannot be reliably sensed with existing flame proving technologies, requires the use of a proven main burner flame under non initial start-up conditions for safe operation. This revision will help avoid unsafe application of this new technology by providing clear and consistent minimum safety requirements.
