1.1
The National Electrical Code (NEC ®) stipulates that "the conductors and
equipment required or permitted by this code shall be acceptable only if
approved" by the Authority Having Jurisdiction (AHJ). The NEC further
states that "suitability of equipment may be identified by a description
marked on or provided with a product to identify the suitability of the product
for a specific purpose, environment or application. Suitability of equipment
may be evidenced by listing or labeling"
1.2 When electrical utilization equipment or machinery has not been listed or
labeled by an independent third party listing or labeling agency, field
evaluation of the equipment or machinery is required by the local electrical
authority having jurisdiction to determine if the equipment complies with the
applicable product standards and codes that are concerned with the safety
of that equipment. The field evaluation is required to be performed by an
independent testing laboratory or engineering firm accredited by the AHJ
using the applicable national product standards that govern the design,
construction, application and testing of the equipment. The field evaluation
body shall provide a label on the equipment evaluated signifying that the
equipment has satisfied the requirements of the applied standards. The
field evaluation body shall forward a copy of the final report to the AHJ
detailing the field evaluation procedures, findings, results and the criteria for
submitting the product to the AHJ for final acceptance.
1.3 Product safety standards are created to address electrical shock and fire
safety concerns in the areas encompassing device construction,
overcurrent protection, temperature rise, grounding and bonding, guarding
personnel from accidental contact with energized components, tamper
proofing, operating environment, safety of personnel during unintended
abnormal operations and product testing to verify suitability of use on the
product in a defined operating environment.
2.0 FIELD EVALUATION SUMMARY
Field evaluation of the equipment listed in section 3.0 was performed between
November 16, 2011 and May 3, 2012, per the requirements of WAC- 296 -46B (44)
at ClearSign Combustion, Tukwila, Washington. The equipment was inspected
and tested to verify conformity with the requirements of the applicable electrical
standards listed in section 4.0. The installation of the equipment was examined to
ensure that it is per the requirements of the manufacturer's technical drawings and
documentation. Any discrepancies identified by PSE and corrected by the client
during the course of the evaluation are shown in section 5.0 along with the
corrective actions taken. PSE field evaluation label was affixed to the equipment.

4.1 UL 508, Industrial Control Equipment
4.2 UL 795, Commercial Industrial Gas Heating Equipment
5.0 EQUIPMENT EVALUATION DETAILS
5.1 Gas Fired Combustion Chamber
5.1.1 Equipment Description
The equipment under investigation was a gas fired combustion test
chamber used for studying the characteristics and properties of
flames patterns. A gas burner is used to provide controlled
combustion which also contains a blower for supplying the air used
in the combustion process. The gas burner incorporates safety
features, where the gas flow is shut off if a flame is not detected in
the chamber. An electronic ignite is used to start the burn
sequence in the chamber once the gas flow is initiated. Appendix A
contains photographs of the equipment. The drawings in appendix
B show the constructional details of the chamber and technical
literature for the gas burner.
5.1.2 Drawings and Documentation
Technical drawings and documentation on the test chamber were
supplied by the client. The documents were reviewed for proper
selection and application of components.
5.1.3 Equipment Inspection
The equipment was inspected for conformity with the applicable
electrical standards. The equipment was inspected to ensure that
all gas piping was properly routed and physically protected. All
electrical devices and wiring was properly protected.
5.1.4 Grounding
Grounding system of the equipment was inspected to verify
conformity with the electrical standards and suitable for the
application.
5.1.5 List of Corrections
5.1.5.1 During the preliminary inspection of the equipment
PSE identified several issues that would require
attention and conformance prior to application of a
third party label. The items are listed below:
1. The equipment shall be provided with a gas pilot burner.
The pilot may be automatically or manually lighted. The
pilot burner shall be provided with a safety shutoff valve.
This may be part of the main gas supply valve. Absence
of pilot flame shall prevent the flow of main burner gas
by automatic means by shutting off the main gas supply.
2. The main gas supply line shall be provided with a safety
shut off valve that may be electrically or pressure
actuated.
3. Manual shut off valves shall be provided in the main and
the pilot gas lines.
4. Air inlet shall be of sufficient cross section to supply
adequate air for complete combustion. Air shall be
introduced in such as manner will ensure thorough
mixing of fuel and air.
5. The outlet flue gas riser shall be positioned away from
combustible material and electrical devices such as
ceiling lights etc. The distance of separation would
depend on the maximum exterior temperature of the
riser.
6. The test chamber requires an equipment grounding
conductor to prevent the accumulation of static charges
on the body of the chamber. The grounding conductor
should be connected to the system ground such as a
ground bus, ground rod or building steel in the vicinity.
7. The test chamber requires a nameplate with the
following information:
• Manufacturer name
• Model #
• Serial #
• Ratings such as BTU or kW
8. External temperature data will be recorded during actual
operation of the chamber in its intended manner. Based
on the data, additional caution markings or corrections
may be required.
The issues identified were verified for correction
during the final inspection.
6.0 ELECTRICAL TESTS PERFORMED
6.1 Ground System Integrity Tests
Tests were performed to verify that the dead metal surfaces of the chamber
and enclosures of electrical devices part of the equipment were satisfactorily
bonded together.
6.2 Safety System Checks
The performance of the safety system for the equipment was checked and
verified. Checks included performance of the gas delivery system and
operation of the flame detection system.
6.3 Temperature Measurement Tests
Temperatures of the external surfaces of the chamber was monitored and
recorded by the user. The test data indicated that the external surface
temperatures were substantially below levels that could be considered
potential heat and fire hazard.
7.0 RESULTS
The equipment evaluated was found to comply with the requirements of the
standards listed in section 4.0. PSE field evaluation label was affixed to the
equipment.

Re: Resw a to- comments for Mechanical Permit No, M11-126
BuiidinR Division Review Memo, September 19, 2001
1. The proposed furnace is required to be listed and labeled f
approved testing agency. if this is not the case, it will need
evaluation by an approved third party agency and labeled on site. Please
confirm the intent.
REVIEWED FOR
CODE COMPLIANCE
APPROVED

VISION
Response: The subject furnace is a research vessel used to provide a safe
environment for burner testing only. It is not used to provide space heat or
produce any product. Please see Item 3 -below fay-- comments regarding the listed
burner. The remainder of the furnace is not listed and labeled but is a simple,
insulated vessel fabricated for ClearSign and functions solely to provide a safe
viewing environment for the flame itself, which is the subject of the research.
The design and insulation calculations are included as Attachment 1 in response
to Item 5, Fire Prevention Division Review Memo, September 19, 2011.
2. Please provide specific details for the rooftop penetration and termination
of the exhaust duct assembly. The exhaust temperature and the exterior
maximum surface temperature of the duct may be needed. Refer to the
code sections that were used to determine the distance to combustible
construction and the height of termination.
Response: The stack temperature will be continuously monitored via a
thermocouple welded to the stack's exterior. The furnace shall be operated so
that the external stack temperature at the roof penetration does not exceed 130
F. The stack installation will be provided per code according to the drawing of
Attachment 2.
3. Please provide manufacturers specs. on the burners. How are they
attached to the furnace.
Response: The burner is a commercial burner: (Wayne Combustion Systems,
P250AF) and is U.L. listed according to the manufacturer's specifications
(Attachment ,3)= The burner will be ducted to the furnace via a botttm? flange (for
location of bottom flange, please see GA drawing (Attachment 4).

4. Please show method of providing combustion air and amount required.
Response: Natural draft is sufficient to provide all combustion air. However, the
burner itself has a small fan. Total required flow rate at maximum firing rate will
be a modest 42 cfm. This should be well within the leakage rate for room air.
Notwithstanding, a 14 "x14" louvered grid will be installed on the rollup door in
the room to allow for makeup air into the space. Additionally, the excess oxygen
in the furnace will be maintained at 3 %, assuring sufficient combustion air. Since
this is a test furnace, 02, CO; NOx, and furnace temperatures will also be
continuously monitored electronically.
5. The furnace and stack measurements in the documents titled "Furnace
Design Basis" do not match the plans and structural calcs. Please clarify.
Response: At one time, two furnaces were contemplated, a large one and a small
one. We have elected to proceed only with the smaller furnace. Unfortunately,
plans for the larger furnace were inadvertently submitted. Accordingly, we have
corrected our submission with the proper furnace calculations as Attachment 1.
6. A plumbing permit will be required for the gas piping. NFPA may require
an emergency gas shut -off.
Response: Acknowledged.
Fire Prevention Division Review Memo, September .19:. 2001
1. How is the furnace fueled? The word "pilot" is used so natural gas fuel is
likely. Please confirm.
Response: The burner will be fueled using natural gas.
2. What is the total output expressed in Btus?
Response: The maximum firing rate for the burner is 250,000 Btu /hr.
3. is the furnace operated under normal atmospheric pressure?
Response: The furnace is operated at just slightly below atmospheric pressure
2
due to the natural draft of the furnace stack.
4. Please provide the manufacturers data sheets (cut sheets) for the furnace.
Response: The furnace vessel was fabricated for ClearSign. ClearSign will install a
manufactured burner into the vessel. See manufacturer's specifications enclosed
as Attachment 3. Wayne Combustion Systems is the manufacturer. Attachment
4 shows the general arrangement drawing. This drawing was also listed in the
original submission package.
5. What are the normal and highest operating temperatures?
Response: Due to the short duration of the testing and the low firing rates, the
normal temperature will be less than 400 F, and often near ambient. However,
on occasion, the interior furnace - temperature may reach 1000 F for limited
duration testing. The furnace has been designed to safely handle an internal
temperature of 2000 F and comprises 6" of high temperature insulation (rated to
2300 F). The temperature of the stack will be electronically and continuously
monitored using a welded thermocouple such that that the external stack
temperature does not exceed a safe level. (Please see "Small Furnace
Performance Calculations" enclosed as Attachment 2.) In addition, there is a 4"
gap between the stack and the roof penetration.
6. What are the products /materials to be heated in the furnace and will there
be any flammable /combustible vapors produced?
Response: The furnace will be a research furnace. ClearSign is a combustion
research company. The furnace will not be used to provide building heat and no
- products or materials will be heated or treated in the furnace. The furnace
functions solely to provide a safe viewing environment for the flame itself, which
is the subject of the research.

Heat Loss for Furnace
With respect to heat loss, the surface temperature is expected to be no less than 120 °F giving a
maximum temperature difference from the furnace interior of 2,180 °F. The inside heat transfer
coefficient may be found by
Nu = hLlk =0.023 Re4t5Pr r3
(3)
where Nu is the Nusselt number, h is the inside heat transfer cne1Ficient, 1. is the characteristic
length, k is the thermal conductivity of the flue gas, Re is the Reynolds number, and Pr is the
Prandlt number.. At 2300 °F, the flue gas specified by .Equation (2) has the following properties:
p = 0.0138 lb /ft3, Cp = 0.3363 Btu/Ibm °F, k = 0.0536 Btu/h•ft•F, and µ = 3.507688.104 lbm/ft•s.
These values give the following.

The average temperature of the insulation will be somewhere between 70 °F and 2300 'F, or an
average temperature of 1185 °F. Duraboardmi insulation at this temperature has a thermal
conductivity of 0.991 Btu -in/hr ft2 F. The furnace has a 'A" carbon steel shell with a thermal
conductivity of k = 300 Btirin/h•ft2•F and 6" of Duraboardnd insulation. We can then obtain an
overall heat transfer coefficient to the furnace surface by adding r sistanc s and inverting to
obtain an overall conductance.

The outside heat transfer coefficient, ho, depends on the wall temperature, which is unknown, but
assumed to be 120 °F for the initial calculation. For a vertical wall, Nu = C Ran where C and n
are coefficients to be determined and Ra is the Raleigh number (also known as the Grashof-
2g number); that is Ra = Gr•Pr and Gr — 2 f3 /T +T . With respect to the Grashof
µ l
number, g is the acceleration doe to gravity) T is the surface temperature, is the ambient
temperature, and the other symbols are previously defined. At the mean film temperature (120 +
70)/2 °F = .95 °F; air .has the following properties: Q =32 174 $ /s2, p = 0.071 6.1hm /ft3, I = 5 _ft,
g = 1.30.10 lbm/ft•s, Ts = 120 °F, = 70 °F, Cp = 0.2416 Btu/lbm °F, and k = 0.0160 Btu/hr ft

The analysis so far neglects heat lost by radiation. The actual surface temperature must be
determined by salving for Q ' hc4(Ts — T�) + 6eA(Ts4 Tc4) }- U4(T — Ts) where a is the Stefan-
Boltzmann constant = 0.1714 x 10 -8 Btu/h•ft2•R4, and e is the emissivity (0.3 for oxidized
metals). Using a two -term Taylor series, one obtains aeA(1 s` —Tos,l) z1 4aeTo3A (TS - To). letting
hr = 4a.eTc3
we obtain
Q =(h +hr)A(T — T)= UA(T —T)
Reanwging this a cation. to sohre for T yields

With e = 0.3, we obtain hr = 4.1.714 x 109.0.3•(70 +460)3 = 0.306 Btu/hr•ft2•F. This can be
increased by painting with white enamel to obtain e = 0.9 (Lo give increased heat ions but lower
skin temperature), giving hr = 0.917 Btu/hr•ft2•F.
Solving for Ts with e = 0.9 gives
UT +(h +hr)T — 0.0758 Btu 2300[F]+(1.48 +0.917) Btu 70[F]

(The same calculations with e = 0.3 gives 161°F, so painting makes decreases the temperature by
23 °F.) This temperature of 138 °F is close enough to 120 °F that properties will not change
s: &aptly. The admi temperature will be WRIeWhere between 120 and 138 F. Using the
average of these temperatures we obtain a surface temperature estimate of

Surface Temperature of Insulated Duct
The stack is a 14" x 14" square stack insulated with 2" of DuraboardTM high efficiency
insulation. Thus the interior dimensions of the stack_ are 10" x 1.0" for an inside cross sectional
area of 0.69 ft2. At a maximum firing rate of 0.25 MMBtuh, this gives an initial interior velocity
in the fiirmee of 6 S3 ills However this velocity will .slow as heat is transferred along the stack
length. Using the worst case of 6.83 ft/s interior velocity and using the calculation method of the
previous section, the maximum internal heat transfer coefficient becomes
h = 0.5681 "hft z •FJ
and the overall heat transfer coefficient to the surface becomes

Equation (4) is solved iteratively with properties adjusted appropriately as the temperature differs
from 170 °F, The combined heat tt- anafer coefficient for radiation and convection is 2.705 Btu/hr

Furnace Design Basis
J. Colannino, 13 May 2011
The general stoichiometry for any hydrocarbon fuel is given by
CHx +(1 +s(1 +4)O2+ 29 )(1+ 0 1 +4 l N2-�
1
(1)
CO2 +(2)H2O +(0(1 +4 O2 +(29 (1 +E 1 +4 N2
\ 1
)
where x is the molar hydrogen/carbon ratio in the fuel, and
e is the excess air
Generally, furnaces run at 10 to 15% excess air. The worst -case scenario is a reactor burning
CH4, as that fuel has the highest air -flow per heat - release requirement. Solving Equation (1) for
CH4 gives
CH4 +2.3002 +8.65N2 - CO2 +2.00H20 +0.3002 + 8.65 N2 (2)
Thus, one volume of CH4 requires 10.95 volumes of air and produces 11.95 volumes of flue gas.
In general, all hydrocarbons have heating values of roughly 20,000 Btu/lb but differ widely on a
volumetric basis. The heating value of methane is 912 Btu/scf (LHV). Therefore, 1 million Btu
(MMBtu) of methane (1096.5 scf) will produce 13,106 scf of flue gas at a wet molecular weight
of 27.78 [lbm/lbmol]. This gives a mass flow rate of roughly 942 [lbm/h]. The actual flue -gas
volumetric flow rate will depend on the furnace temperature. Using a standard basis of 70 °F and
adjusting to the maximum furnace temperature of 2300 °F (ethylene cracking furnace) inflates
the volume by a factor of 5.21.
• 1 MMBtuh CH4 = 19.0 ACFS
Stack Diameter
In general somewhere between 0.25 and 4.00 inches of water column (iwc) draft is available in
industrial furnaces, the limiting case being the lowest draft, 0.25 iwc. An energy balance allows
gives the equivalent velocity motivated by 0.25 iwc.
v e 2g,Ap
where v is the velocity (ft/s)
lbm ft
gc is a dimensional constant, 32.174 lbf s2 —1, required for
Ap is the draft pressure, iwc, and
p is the density, lbm/ft3.
Furnace Design Basis_R3 14 June, 2011
The density of flue gas at 2300 °F (using the flue gas stoichiometry given by Equation 2) is
0.0138 lbm/f13. Then 0.25 iwc gives
V =
1
2.32.174 ibm ft , 0.25{iwc]
lbf s2
2 - 6.50 ft/s = 390 ft/min = 23,400 ft/hr
0.0144 ibm 27 67 iwc in
ft3 lbf
Since we require 18.96 ACFS for 1 MMBtuh and can motivate 6.50 ft/s at 0.25 iwc, the required
area of the duct must be 2.92 ft2. This is equivalent to a 23.2" inside diameter or a 20.5" x 20.5"
square duct.
• Thus, a 24" diameter stack internally insulated with -2" of insulation will be sufficient.
Furnace Dimensions
Generally, velocities of 80 ft/min are typical in furnaces. This requires about 4.87 times the duct
area or14.2ft.
• A 4' x 4' square furnace (internal dimensions) would fit the bill.
Generally, low NOx flames (worst case) produce about 3' per million BTU. A general rule of
thumb for a test furnace is to double the required flame height.
• A 6' tall furnace (inside dimension) will be sufficient.
Heat Loss
With respect to heat loss, the surface temperature is expected to be no less than 120 °F giving a
maximum temperature difference from the furnace interior of 2,180 °F. The inside heat transfer
coefficient may be found by
Nu = hL /k =0.023 Re445PrIr3
(3)
where Nu is the Nusselt number, h is the inside heat transfer coefficient, L is the characteristic
length, k is the thermal conductivity of the flue gas, Re is the Reynolds number, and Pr is the
Prandlt number. At 2300 °F, the flue gas specified by Equation (2) has the following properties;
p = 0.0138 lb /ft3, C, = 0.3363 Btu/lbm °F, k= 0.0536 Btu/h•ft•F, and µ = 3.507688.104 lbm/ft•s.

The average temperature of the insulation will be somewhere between 70 °F and 2300 °F, or an
average temperature of 1185 °F. DuraboardTM insulation at this temperature has a thermal
conductivity of 0.991 Btu -in/hr 112 F. We can then obtain an overall heat transfer coefficient to
the furnace surface by adding resistances and inverting to obtain an overall conductance.

The foregoing presumes a 3/16" carbon steel shell having k = 300 Btu•in/h•ft2•F and 6" of
DuraboardTM insulation.
The outside heat transfer coefficient, ho, depends on the wall temperature, which is unknown, but
assumed to be 120 °F for the initial calculation. For a vertical wall, Nu = C Ra" where C and n
are coefficients to be determined and Ra is the Raleigh number (also known as the Grashof-

Furnace Surface Temperature
The analysis so far neglects heat lost by radiation. The actual surface temperature must be
determined by solving for Q = h0A(T3 — T.) + aeA(Ts4 —T,4) = UA(T — Ts) where a is the Stefan -
Boltzmann constant = 0.1714 x 10.8 Btu/h • ft • R , and e is the emissivity (0.3 for oxidized
metals). Using a two -term Taylor series, one obtains aeA(T34 —T.4)::=. 4oeT.3A (Ts — T.). Letting
hr = 4aeTo3 we obtain Q = (ho + hr)A(Ts — T.) = UA(T — Ts). With e = 0.3, we obtain hr =
4.1.714 x 1 0-9• 0.3 . (70+460)3 = 0.306 Btu/hr • ft • F. This can be increased by painting with white
enamel to obtain e = 0.9 (to give increased heat loss but lower skin temperature), giving hr =
0.919 Btu/hr•ft •F.

Insulation Thickness and Adjusted Temperature
Since this temperature is not 120 °F, technically we must iterate and adjust properties
accordingly until the temperatures converge. However, the shell temperature must be somewhere
between 120 °F and 149 °F and will be likely near the average of 135 °F. With 6" of insulation
the heat loss becomes

Building Division Review Memo #2
Date: November 21, 2011
Project Name: Clear Sign Combustion
Permit #: M11 -126
Plan Review: Dave Larson, Senior Plans Examiner
The Building Division conducted a plan review on the subject permit application. Please address the
following comments in an itemized format with revised plans, specifications and/or other applicable
documentation.
(GENERAL NOTE)
PLAN SUBMITTALS: (Min. size 11x17 to maximum size of 24x36; all sheets shall be the same size).
(If applicable) Structural Drawings and structural calculations sheets shall be original signed wet
stamped, not copied.)
1. As I understand your response to correction letter #1, you are proposing to not have the
fumace listed. The bumer would be listed. You will provide a Thermocouple welded to the
stacks exterior to limit stack temperature and you will add a 14 x14 inch louvered combustion
air opening to the roll -up door. I have no way to evaluate this furnace and stack for code
compliance. Follow -up phone conversations with the architect stated that you would have the
furnace and stack listed by an approved third party listing agency. Please confirm this
proposal and you may want to confirm the listing agencies ability to provide said listing on
both the fumace and the stack.
Confirmed. The furnace and bumer will be certified as UL equivalent. We currently envision
that the third party listing agency will be Power Science Engineering and completed by
C. (Sank) Sank ran.'�6 1,19%.14 *µtit WILL Aix \fair( gC1 4 'tl4 ' AP
2. The furnace sounds like it may be a medium heat appliance. Section 503.5.4 of the
International Fuel Gas Code requires the chimney to terminate 10 ft. above any portion of any
building within 25 feet. The provided plan shows the chimney extending 20 inches above the
roof. Also the plan shows 4 inches clearance at the roof penetration. Please provide the code
section used to determine this clearance. A thermocouple will be provided to maintain
maximum exterior surface temperature of the stack. Will this thermocouple be interlocked
with the furnace to stop flow of gas when maximum temperature is exceeded?
After closer review of the International Fuel Gas Code, we have elected to construct a
chimney that will be 10 ft. above the roof line. Two wet copies of structural calculations are
submitted as well as drawings of the furnace and stack.
• Page 1
• •
3. The combustion air opening will need to have dampers to close off outside air when the
furnace is not in use. Will they be barometric or electrically connected to the fumace
operation?
We are planning to use a manual damper in the stack that will be closed when the fumace is
not in operation. In addition, a manual inlet register at the entrance to the furnace will also be
closed to isolate the outside air from the room air when the fumace is not in use.
4. Please verify if an emergency shutoff device will be installed and where.
A manual shutoff for the main gas line will be located away from the fumace to provide a
remote shutoff.
Should there be questions conceming the above requirements, contact the Building Division at 206-
431 -3670. No further comments at this time.
