SUPPLEMENTARY INFORMATION: In a petition received July 21, 2015,
Johnston requested that the U.S. Department of Energy (``DOE'') grant a
waiver to certain models of larger commercial package boilers that
cannot be tested under the existing DOE test procedure. The models of
commercial packaged boilers at issue are models with higher input
capacities that typically require higher steam pressure and alternative
instrumentation due to the large quantities of fluids being measured.
I. Background and Authority
Title III, Part C of the Energy Policy and Conservation Act of 1975
(EPCA), as amended (42 U.S.C. 6311 et seq.), established the Energy
Conservation Program for certain industrial equipment, which includes
commercial packaged boilers.\1\ Part C specifically includes
definitions (42 U.S.C. 6311), energy conservation standards (42 U.S.C
6313), test procedures (42 U.S.C. 6314), labeling provisions (42 U.S.C.
6315), and the authority to require information and reports from
manufacturers (42 U.S.C. 6316). Part C authorizes the Secretary of
Energy (the Secretary) to prescribe test procedures that are reasonably
designed to produce results that measure energy efficiency, energy use,
and estimated annual operating costs, and that are not unduly
burdensome to conduct. (42 U.S.C. 6314(a)(2)) With respect to
commercial packaged boilers, Part C requires DOE to use industry test
procedures developed or recognized by the Air-Conditioning, Heating,
and Refrigeration Institute (AHRI) or the American Society of Heating,
Refrigerating, and Air-Conditioning Engineers (ASHRAE), as referenced
in ASHRAE/IES \2\ Standard 90.1, ``Energy Standard for Buildings Except
Low-Rise Residential Buildings.'' (42 U.S.C. 6314(a)(4)(A)) Further, if
such an industry test procedure is amended, DOE is required to amend
its test procedure to be consistent with the amended industry test
procedure, unless it determines, by rule published
[[Page 38162]]
in the Federal Register and supported by clear and convincing evidence,
that the amended test procedure would be unduly burdensome to conduct
or would not produce test results that reflect the energy efficiency,
energy use, and estimated operating costs of that equipment during a
representative average use cycle. (42 U.S.C. 6314(a)(4)(B)). The test
procedure for commercial packaged boilers is contained in 10 CFR part
431, subpart E.
---------------------------------------------------------------------------
\1\ For editorial reasons, upon codification in the U.S. Code,
Part C was re-designated Part A-1.
\2\ Illuminating Engineering Society.
---------------------------------------------------------------------------
DOE's regulations for covered products and equipment permit a
person to seek a waiver from the test procedure requirements for
covered commercial equipment if at least one of the following
conditions is met: (1) The petitioner's basic model contains one or
more design characteristics that prevent testing according to the
prescribed test procedures; or (2) the prescribed test procedures may
evaluate the basic model in a manner so unrepresentative of its true
energy consumption as to provide materially inaccurate comparative
data. 10 CFR 431.401(a)(1). A petitioner must include in its petition
any alternate test procedures known to the petitioner to evaluate the
basic model in a manner representative of its energy consumption. 10
CFR 431.401(b)(1)(iii).
DOE may grant a waiver subject to conditions, including adherence
to alternate test procedures. 10 CFR 431.401(f)(2). As soon as
practicable after the granting of any waiver, DOE will publish in the
Federal Register a notice of proposed rulemaking to amend its
regulations so as to eliminate any need for the continuation of such
waiver. As soon thereafter as practicable, DOE will publish in the
Federal Register a final rule. 10 CFR 431.401(l).
II. Petition for Waiver of Test Procedure
On July 21, 2015, Johnston submitted a petition for waiver from the
DOE test procedure for certain basic models of its commercial packaged
boilers. The DOE test procedure for commercial packaged boilers is set
forth at 10 CFR 431.86 and incorporates by reference Hydronics
Institute (HI) BTS-2000, ``Method to Determine Efficiency of Commercial
Space Heating Boilers'' (BTS-2000).
According to Johnston, there are several issues that make BTS-2000
incompatible with larger commercial packaged boilers, including those
identified in its petition for waiver. Johnston stated that the
requirements to use test conditions specified in BTS-2000 and the
instrumentation requirements are outdated. Specifically, Johnston
indicated the following regarding the test conditions:
The 0 to 2 psig test pressure for steam boilers may be
adequate for residential and small commercial (cast iron) boilers sized
[commercial packaged] boilers, however such steam pressures are not
compatible with large [commercial packaged] boilers as it will cause
water carryover in large quantities, and an inability to meet design
water flow rates and firing rates;
Typically test steam pressures in the range of 10 to 12
psig are required; and
Test temperatures defined for hot water [commercial
packaged] boilers cause thermal shock problems in large [commercial
packaged] boilers.
Johnston also indicated the following regarding the instrumentation
chart in Table 1 of section 6.0, ``Instruments,'' of BTS-2000:
Steam pressure cannot be measured by mercury manometer as
the use of mercury in instruments and controls is banned; the correct
instrument is a Bourdon Tube Gauge for pressures of 0 to 30 psig;
Large boilers typically fire into a positive pressure
combustion chamber, thus gas pressure, firebox pressure and vent/flue
pressure instruments all need to reflect this;
The use of scales to measure water/condensate/moisture
flow rates is incompatible with the volume of these fluids being used
or generated by large [commercial packaged] boilers; water flow meters
should be used and in the case of moisture content, current practice is
to use a throttling calorimeter;
The measurement of carbon dioxide as a means of
calculating excess air or oxygen is considered obsolete in the large
[commercial packaged] boiler industry; direct measurement of excess
oxygen is the preferred method as modern oxygen meters can easily be
calibrated against the oxygen in the ambient air;
Carbon Monoxide levels are no longer measured as a
percentage; the current preferred unit is parts per million (ppm).
To address these concerns, Johnston proposes to use the newly
published American National Standards Institute (ANSI)/Air-
Conditioning, Heating, and Refrigeration Institute (AHRI) 1500-2015,
``Standard for Performance Rating of Commercial Space Heating Boilers''
(ANSI/AHRI Standard 1500-2015) in place of BTS-2000. AHRI developed
ANSI/AHRI Standard 1500-2015 as a replacement for BTS-2000 in order to
make the test procedure suitable for use with larger commercial
packaged boilers, as well as improve and clarify the test method.
Johnston claims that use of this ANSI/AHRI Standard 1500-2015 is
necessary as it is compatible with the size of commercial packaged
boilers they manufacture.
Additionally, for the large commercial packaged boilers capable of
supplying either steam or hot water identified in this petition,
Johnston requests that, when determining the combustion efficiency in
hot water mode based on testing in steam mode only, the combustion
efficiency rating be determined based on an adjusted combustion
efficiency. Johnston requests that an adjustment be made to the
measured stack temperature to be used in calculating combustion
efficiency based on the relative difference between the flue gas
temperature and the bulk fluid temperature when operating in steam mode
as opposed to hot water using the following relationship:
Tstack, hw = (Tstack, steam - Tsat) +
Tbulk, hw
where Tstack, hw is the stack temperature to be used to
determine the combustion efficiency in hot water mode,
Tstack, steam is the measured stack temperature when testing
on steam, Tsat is the saturation temperature of steam at the
test pressure, and Tbulk, hw is the temperature of the
outlet water when testing in hot water mode and is equal to 180 [deg]F.
According to Johnston, using this adjusted stack temperature to
calculate combustion efficiency is a more accurate representation of
the actual efficiency when operating as a hot water commercial packaged
boiler than simply using combustion efficiency value for steam mode.
Johnston also requests to use the vertical stack arrangement shown
on their ``Drawing #327A0040 Johnston Boiler General Arrangement D.O.E.
Efficiency Test (attachment B).'' DOE's existing test procedure
incorporates section 7.0 ``Apparatus'' of BTS-2000 with respect to test
setup including flue connection requirements. (DOE notes that the term
``flue,'' not ``stack,'' is used throughout its test procedure
regulations as well as BTS-2000). The flue requirements differ
depending on the characteristics of the commercial packaged boiler,
including:
Whether the unit is oil-fired or gas-fired, and if gas-
fired;
Whether the unit is direct vent;
Whether the unit has an input rating of more than 400,000
Btu/h;
Whether the unit is discharges vent gases horizontally or
vertically; and
Whether the unit is condensing.
According to Johnston, the large volume of flue gas in relation to
the flue
[[Page 38163]]
diameter results in relatively high velocities and therefore creates
turbulence. Johnston indicates that this straight stack arrangement is
shown in their operating manual and in the American Boiler Manufacturer
Association's (ABMA) ``Packaged Boiler Engineering Manual.'' DOE
requests comment on how turbulence affects measured efficiency under
the current test procedure, and how use of the vertical stack
arrangement shown in the drawing provided by Johnston would prevent
turbulence.
In addition, Johnston stated that ANSI/AHRI Standard 1500-2015 does
not clarify whether there is an upper limit for fuel input rate to
which the standard applies. However, the scope of ANSI/AHRI Standard
1500-2015 is identified as ``commercial space heating boilers'' in
section 1.1. (Note: The term ``commercial space heating boiler'' is not
defined in ANSI/AHRI Standard 1500-2015.) Johnston suggested that the
upper fuel input rate limit be established at 12,500,000 Btu/hr.
Johnston stated that the two major safety standards for the industry
are American Society of Mechanical Engineers (ASME) CSD-1 Controls and
Safety Devices for Automatically Fired Boilers (ASME CSD-1) and
National Fire Protection Association (NFPA)-85-2015 Boiler and
Combustion Systems Hazard Code (NFPA-85). Johnston further indicated
that the scope of ASME CSD-1 is for commercial boilers with inputs from
400,000 to 12,500,000 Btu/hr and the scope for NFPA-85 is for
industrial boilers over 12,500,000 Btu/hr. DOE notes that neither the
existing DOE test procedure or energy standards establish an upper
limit in terms of fuel input rate for which they apply. Consequently,
DOE is declining to consider Johnston's request for an upper limit for
the fuel input rate which would limit the scope of applicability of the
test procedure in this proceeding.
DOE notes that it has published a notice of proposed rulemaking
(NOPR) to amend its test procedure for commercial packaged boilers
prescribed in 10 CFR part 431 subpart E (March 2016 CPB TP NOPR). 81 FR
14641 (Mar. 17, 2016). The proposed amended test procedure addresses,
among other changes, most of the issues raised in this waiver request
by incorporating by reference ANSI/AHRI Standard 1500-2015 as a
replacement for BTS-2000 in the DOE test procedure for commercial
packaged boilers. In addition to adopting ANSI/AHRI Standard 1500-2015
as a replacement for BTS-2000, DOE further proposes several
modifications to its test procedure that are not captured in ANSI/AHRI
Standard 1500-2015 in order to improve repeatability, add
clarification, and accommodate testing of some equipment that has
experienced difficulty in testing to the existing DOE test procedure.
Among these changes, DOE proposes to adopt the stack temperature
adjustment described by Johnston when using the tested combustion
efficiency of large steam commercial packaged boilers to represent the
combustion efficiency of large commercial packaged boilers in hot water
mode.

Application for Waiver for the Efficiency Rating of Commercial Space
Heating Boilers
In accordance with the provisions of the Code of Federal
Regulations Part 431, paragraph 431.401, Johnston Boiler Company is
hereby petitioning for a waiver from the following test procedures
specified for Commercial Packaged Boilers:
1. Paragraph 431.86 Uniform test method for the measurement of
energy efficiency of commercial packaged boilers. This section
requires the boilers be tested using the provisions of HI BTS-2000.
We propose to use the newly published AHRI 1500, 2015 Standard for
Performance Rating of Commercial Space Heating Boilers. There are
several issues that make BTS 2000 incompatible with the larger
boilers that were identified in previous waiver requests. AHRI has
worked diligently over the past year to revise BTS-2000 in order to
address those issues and make BTS-2000 suitable for use with larger
boilers. AHRI Standard 1500 is the result of that work. Use of this
new standard is required as it is compatible with the size boilers
we manufacture.
2. Paragraph 431.86(c)(1)(iv) The requirement to use test
conditions specified in BTS-2000 specifically the requirements for
the test pressure for steam boilers, the required water temperatures
for hot water boilers and instrumentation requirements seem to refer
back to the middle of the last century rather than the present day,
for example:
The 0 to 2 psig test pressure for steam boilers may be
perfectly adequate for residential and small commercial (cast iron)
boilers sized boilers, however is not compatible with large boilers
as it will cause water carryover in large quantities, and an
inability to meet design water flow rates and firing rates.
Typically test pressures in range 10 to 12 psig are required.
Test temperatures defined for hot water boilers are
guaranteed to cause thermal shock problems in large boilers.
The instrumentation chart, Table 1, has several problem
areas, as follows:
[cir] Steam pressure cannot be measured by mercury manometer as
the use of mercury in instruments and controls is banned. The
correct instrument is a Bourdon Tube Gauge 0 to 30 psig
[cir] Large boilers typically fire into a positive pressure
combustion chamber, thus gas pressure, firebox pressure and vent/
flue pressure instruments all need to reflect this.
[cir] The use of scales to measure water/condensate/moisture
flow rates is incompatible with the sheer volume of these fluids
being used or generated by large boilers. Water flow meters should
be used and in the case of moisture content, current practice is to
use a throttling calorimeter.
[cir] The measurement of carbon dioxide as a means of
calculating excess air or oxygen is considered obsolete in the large
boiler industry. Direct measurement of excess oxygen is the
preferred method as modern oxygen meters can easily be calibrated
against the oxygen in the ambient air.
[cir] Carbon Monoxide levels are no longer measured as a
percentage. The current preferred unit is ppm.
AHRI 1500 has taken into account these changes.
3. Paragraph 431.86(c)(2)(iii)(B) Rating. This paragraph
specifies that for boilers capable of supplying either steam or hot
water, that they are tested on steam only, the hot water efficiency
shall be based on the testing in the steam mode. We propose to use
an adjusted steam efficiency for hot water when testing on steam
only. The adjustment is made to the measured stack temperature to be
used in calculating efficiency based on the relative difference
between the flue gas temperature and the bulk fluid temperature when
operating on steam v hot water using the following relationship:
Tstackhw = (Tstacksteam - Tsat) +
Tbulkhw
Where:
Tstackhw = Stack temperature to be used to determine the
efficiency on hot water
Tstacksteam = Measured stack temperature when testing on
steam
Tsat = Saturation temperature of steam at the test
pressure
Tbulkhw = 180 [deg]F
The dominant heat transfer variable for both steam and hot water
boilers is the gas side coefficient and there is very little
difference in the overall heat transfer coefficient between steam
and hot water boilers. It is possible therefore to determine what a
hot water boiler stack temperature will be, based on a steam test
and the bulk fluid temperature difference within the boiler. We
believe that using this adjusted stack temperature to calculate
efficiency is a more accurate representation of the actual
efficiency when operating as a hot water boiler than simply using
the steam efficiency value.
4. We will use the vertical stack arrangement shown on our
Drawing #327A0040 Johnston Boiler General Arrangement D.O.E.
Efficiency Test (attachment B). The large volume of our flue gas in
relation to the flue diameter results in relatively high velocities
with resulting turbulence. This straight stack arrangement is shown
in our operating manual and ABMA's ``Packaged Boiler Engineering
Manual''.
5. AHRI Standard 1500, Page 1, Section 2, Paragraph 1.1 and 2.2.
It is not clear if there is an upper limit for input rating.
However, the stated purpose of the AHRI standard 1500 is for
Commercial Space Heating Boilers. We suggest that the upper input
limit be established at 12,500,000 Btu/hr.
The two major safety standards for our industry are American
Society of Mechanical Engineers (ASME CSD-1 Controls and Safety
Devices for Automatically Fired Boilers) and National Fire
Protection Association (2015 NFPA-85 Boiler and Combustion Systems
Hazard Code). The scope of CSD-1 is for Commercial Boilers with
inputs from 400,000 to 12,500,000 Btu/hr. The scope for NFPA-85 is
for Industrial Boilers over 12,500,000 Btu/hr.
The basic models that this request is applicable to are as
follows:
