5.0 Description and Principle of Operation
APPLICATION
The Ammonia (NH3) Converter is typically bolted to the side of, and plumbed to, a 270 series probe. The
assembly is designed to sample gas in stacks where ammonia is added and must be analyzed. There is an
unconverted sample output located immediately after the filter on the probe. A second sample connection is
made after the converter. NO is analyzed from samples at both locations, and the difference in concentration
is a measure of the amount of ammonia that has been converted.
All other standard model 270 probe options may be ordered along with the ammonia converter, including high
pressure blowback functions, calibration gas injection, and all standard flange sizes. Refer to the specific
model 270 manuals for more information regarding the probe specifications.
GENERAL DESCRIPTION, HEATED FILTER SECTION
The Heated Stack Filter Section of the NH3 Conversion Assembly consists of the 270 heated filter mounted
on the left side of the converter and contains a blowback solenoid valve to be activated by external means. An
acid blocking component is provided to protect the valve from acid in the sample. The solenoid valve can be
provided with any of the available solenoid coils to allow the external control system to provide the opening
coil power which is most convenient.
The NEMA 4X enclosure is fastened directly to the mounting flange which is sized to match the mating
sample flange on the stack. There is a heat shrink boot on the bottom of the enclosure to accept a heated
sample line. When the heated sample line is properly supported, the flange mounting of the enclosure is
sufficient to support the entire assembly.
A 125 watt Heater Assembly is mounted on the outside of the filter cavity. The heater holds the temperature
of the filter at 340°F. A bi-metallic thermal switch fused to the heater keeps the temperature from exceeding
340°F (171°C) by opening the circuit at that temperature. An optional independent thermocouple/RTD can be
provided as a means to measure and transmit or record the temperature of the filter. A second thermal switch,
set at 225°F (105°C.) is provided to be used as an alarm contact if the temperature drops below the switch
temperature.
Several types of filter elements can be supplied with the Model 270. The 2 μm ceramic filter is supplied as an
economical general purpose filter. A similar ceramic filter with an internal 0.1 μm coating is available for finer
filtration or to provide a surface to enhance the blowback capability where the fines have a tendency to fill the
pores of the 2 μm element. A 2μm, 316SS filter can be inserted for those applications where the ceramic filter
is determined to be unsuitable. Additional filtration materials and pore sizes are available on request.
The blowback accumulator is a 7” diameter stainless steel sphere. It is designed to be pressurized to a
maximum pressure of 125 psig compressed air. At that pressure there is a 1/2 cubic foot of air stored to flush
the particulate matter out of the filter and through the probe and into the stack.
Compressed air is used to clean the filter element. Compressed air supplied to the blowback assembly needs
to be clean and dry. Instrument quality air is preferred. The pressure should be as high as possible, up to 125
psig. High pressure air fills the accumulator and provides a substantial blast when the solenoid valve opens.
This loosens the particles on the filter surface and forces them back through the sample probe into the stack.
The period of time between blowback cycles should be commanded to occur before the pressure drop across
the filter begins to increase. This should be as often as every 15 minutes but no less frequently than once per
day. The time period between blowback cycles can be based on a calculation to estimate the amount of
sample required to deposit from 3 to 5 grams of solid in the filter element.
Instrument air usage is minimal and smoothed by the fact that the air accumulator is charged over a period of
time through a 1/4” instrument air line. The recharge time could be extended with a restriction in the air line, if
it were desired to reduce the pressure pulses on the instrument air supply and to consume instrument air
more slowly.

270NH3.MAN.REVD.062019 Page 8 of 17
GENERAL DESCRIPTION, AMMONIA CONVERSION SECTION
The NH3 converter mounts to the right side of a standard 270 series probe enclosure. The probe enclosure is
fastened directly to a mounting flange on the stack. A heat shrink boot on the bottom of the probe enclosure
provides a sealed input location for all sample lines and electrical wiring for both units.
Tubing connects one of the heated probe filter outputs to the input on the NH3 converter. This tubing is
wrapped with a heater to ensure that no condensate forms. This heater, along with the heater inside the
converter chamber, is terminated in the probe enclosure, where user power is provided.
Blowback is typically provided with the probe assembly to flush particulate matter out of the filter. When the
accumulator sphere is discharged, small amounts of air will also travel through the converter. Blowback air
does not harm the converter but will momentarily disturb both sample outputs. Clean and dry instrument
quality air is essential to avoid particulate buildup in the converter chamber. Typical blowback time intervals
are user controlled, as frequent as every 15 minutes, but not more` than 24 hours.
Calibration (cal) gas is injected into the probe chamber, ahead of the filter. This fulfills most EPA
requirements for cal gas insertion with respect to proximity of the sample source. A back-pressure check
valve, set to approximately 3 psi, is provided in the cal gas injection path to ensure that the gas does not leak
into the sample path during normal operation. After the filter, cal gas is drawn through both the converted and
unconverted sample outputs.
The converter canister provides a torturous gas path through 316 stainless steel disks and balls, with elevated
surface temperatures above 1200°F. The temperature of the chamber is user controlled via monitoring of the
pre-installed type K thermocouple which is welded to the chamber core. The oven temperature may be safety
controlled up to 1500°F; however, the stainless steel surfaces, along with the ammonia gases, oxidize at the
high end of the range, reducing the service life of the reactor.
As the sample passes through the reactor, all NOX and NH3 are thermally oxidized into Nitric Oxide (NO).
Reaction of NH3 proceeds according to this exothermic reaction:
4 NH3 + 5 O2 → 4 NO + 6 H2O
The controlled temperature, gas concentration, and flow rate through the converter should be optimized by
each user through empirical means. It is recommended to first test the conversion efficiency at 1250°F. Most
applications result in as high as 95% effectiveness at this temperature. Testing above 1500°F has shown to
reduce effectiveness in many instances.
For maximum conversion efficiency and long reaction life (several years), observe the following:
 Ratio of O2 to NH3 should be greater than 1.25.
 Flow through the reactor should be limited to 1 – 1.5 l/m.
 Do not expose the reactor to ammonia concentrations > 20 ppm.
 Minimize (NH3 ppm * hours * flow rate) for longest reactor life.

270NH3.MAN.REVD.062019 Page 9 of 17
6.0 Installation
The Ammonia Converter is typically bolted to the side of a probe enclosure, which provides all the structural
support necessary. Interfacing to the stack, connecting to sample bundles, and termination of electrical wiring
is done through the probe assembly. The probe mounts to a flange face, which should be vertical or canted
slightly to allow any entrained liquid in the sample to drain back into the stack. The probe tube should extend
into the center third of the stack.
Heated sample line bundles should be supported externally to the probe housing, such that no weight is
transferred to the enclosure wall. Connect the two sample tubes to the appropriate fittings before and after
the converter. Unheated portions of these tubes should be kept to a minimum to avoid condensation. The cal
gas input line connects directly to the check valve on the side of the chamber. The blowback instrument air
tubing connects to the fitting close to the accumulator sphere. If an external air line is to be utilized, use a
bulkhead fitting in the side of the probe enclosure for support.
Electrical terminals in the probe enclosure provide connections to the converter heater and thermocouple.
Drawings in the back of this manual should be used for reference only, since wiring of different probe models
will vary slightly. Always be sure that the power supplied to the probe and the NH3 converter matches the
voltage requirement shown on the serial number tag. Type K thermocouple extension wire should be used in
the bundle to connect to the temperature controller. A solid state relay may be necessary in the heater
control process. Approximately 1250 watts of power is required. An independent ground wire should be run
to the grounding terminal in the probe enclosure.
Secure the enclosure and ensure that the sample tubing is kept at a temperature above the dew point of the
gas all the way to the cooler/dehydrator.

270NH3.MAN.REVD.062019 Page 10 of 17
7.0 Start-Up
Apply power to the unit. Allow the probe filter chamber and NH3 converter to come up to operation
temperature. This warm-up period is extremely important to avoid condensation, which can cement
particulates to the filter surface and in the converter path.
Only after the unit has come up to full temperature, start the gas sample pump(s) and determine that the
proper amount of sample is being supplied to secondary instrumentation.
Run a calibration cycle to ensure that tubing is properly installed and sealed. A flow meter should be installed
in the cal gas supply line to ensure that at least 10% more gas is being supplied than what is withdrawn as
sample. This calculation should include the sum of the unconverted and converted sample paths. Excess cal
gas is discharged through the probe into the stack.
Charge the accumulator and manually perform a blowback cycle to ensure proper wiring. A slight pulse of
instrument air in the sample tubing will cause a momentary dilution of sample at the analyzers. This is normal
and signifies that a blowback cycle has occurred.
AMMONIA OXIDATION TEMPERATURES
It is suggested that the temperature of the reactor oven be first controlled to 1250°F (677°C). to determine if
satisfactory ammonia conversion efficiencies can be obtained at that temperature.

270NH3.MAN.REVD.062019 Page 11 of 17
8.0 Shutdown
1. It is recommended to introduce inert gas or instrument air through the cal gas port for 15 to 30
minutes to purge the filter chamber, NH3 converter, and sample lines of potentially hazardous
substances.
2. Shut down the sample pump before the end of the purge cycle to avoid drawing in new gasses.
3. Filter replacement may now be safely performed. Caution: The filter chamber is typically controlled to
temperatures above 300°F and can cause serious burns.
4. For further disassembly, shut down all heaters in the probe and converter.
5. It is recommended to flow instrument air through the converter for several hours to cool down to
acceptable temperatures. Caution: The NH3 canister operates at temperatures above 1250°F and
can cause serious burns. Depending on the installation and application parameters, the well-
insulated chamber may take up to 24 hours for a sufficient cool down period.
6. Turn off instrument air for blowback and manually perform a blowback cycle to empty the accumulator
chamber and reduce any stored energy in the system.

270NH3.MAN.REVD.062019 Page 12 of 17
9.0 Maintenance
CHANGING THE FILTER
CAUTION: THIS PROCEDURE CAN CAUSE SEVERE BURNS. USE PROPER
PROTECTION.
Changing the filter in the Model 270 Heated Filter Assembly is extremely easy. Using gloves to protect the
hand, grasp the cap on the end of the filter body opposite the probe and turn it counterclockwise. The cover
may be hot to the touch and may cause burns to the hand if not protected. Removing the cover exposes the
filter. The cover is secured to the assembly with a retainer chain. Reach into the heated oven with pliers to
pull out the old filter.
Inspect the O-Rings which are at each end of the filter to ensure they are still elastic and will seal the filter.
Replace O-Rings if they are charred or deformed.
Replace the filter with a new one, again handling it with pliers. Ensure that the filter is pushed in the center of
the oven so that it is in contact with the O-Ring on the far end of the filter. Screw the cap back on the filter
body. The filter replacement procedure is complete.
NH
3
CONVERTER
The NH
3
Converter requires relatively little maintenance, but over a long period of time (years), the
effectiveness can drop off due to oil and oxidation coatings on the internal components. This is measurable
by comparing the cal gas analysis through both sample ports. When the converter effectiveness is no longer
acceptable, a replacement chamber may be installed.
Complete a full shutdown sequence and include enough time for adequate cool down. The canister starts at
over 1250°F and is well insulated, so cool down may take up to 24 hours. Pumping instrument air through the
canister will reduce cool down time.
1. Unbuckle the ceramic heater/insulator strap and open the front half of the unit. There should be
adequate room to leave the heater wired up and still perform the swap.
2. Slide the thermocouple down and out of the canister.
3. Loosen the fittings from the canister tubes at the bulkhead wall and remove the canister.
It is not recommended to perform maintenance on any other part of the converter assembly.

supply of technical information such as drawings or
specifications.
C. Proprietary information, including drawings, documents,
technical data, reports, software, designs, inventions and other
technical information supplied by Seller in connection herewith
(hereinafter called "Data"), shall remain Seller's sole property
and shall be held in confidence by Buyer. Data shall not be
reproduced, used or disclosed to others by Buyer without
Seller’s prior written consent. Upon completion of Order, Buyer
shall promptly return all Data to Seller together with all copies
or reprints thereof then in Buyer's possession or control, and
Buyer shall thereafter make no future use, either directly or
indirectly, of any Data or any information derived therefrom
without Seller's prior written consent. The foregoing shall in no
way obligate Seller to provide or supply Data.

Seller.
XII. GENERAL
A. The rights and obligations of the Buyer and Seller hereunder
shall be governed in all respects by the law of the
Commonwealth of Pennsylvania, U.S.A. The exclusive forum
for adjudication of any disputes shall be the federal or state
courts of the Commonwealth of Pennsylvania, and Buyer/Seller
hereby consent to personal jurisdiction and venue in such
courts in any proceeding. The United Nations Convention on
the International Sale of Goods shall not apply.
B. These Terms and Conditions of Sale together with any other
terms specifically agreed to in writing by Seller constitute the
entire agreement between Buyer and Seller and supersede any
prior or contemporaneous representations, agreements,
proposals, warranties, or understandings, oral or written,
express or implied. No waiver, modification, amendment,
rescission or other change to these Terms and Conditions of
Sale shall be binding unless specifically agreed to in writing by
an authorized representative of Seller.
C. The invalidity, of any part hereof shall not affect the validity
of the remainder. The failure of Seller to assert any right at any
time hereunder shall not prevent Seller's subsequent assertion
of the same or different rights.
D. Buyer may not assign this contract without the prior written
approval of the Seller.
XIII. PROHIBITION FOR HAZARDOUS USE
Products sold hereunder are not intended for application in,
and shall not be used by Buyer in construction or application of
a nuclear installation or in connection with use or handling of
nuclear material or for any hazardous activity or critical
application, where failure of a single component could cause
substantial harm to persons or property, unless Products have
been specifically approved for such activity or application.
Seller disclaims all liability for loss or damage resulting from
such unauthorized use and Buyer shall defend, hold harmless
and indemnify Seller against any such liability, whether arising
under breach of contract, warranty, tort (regardless of the
degree of fault or negligence), strict liability or otherwise.
Where Seller approves the application of the Products in a
nuclear facility, the Buyer shall, before such use or provision,
arrange for insurance or governmental indemnity protecting the
Seller against liability and hereby releases and agrees to
indemnify the Seller and its suppliers for any nuclear damage,
including loss of use, in any manner arising out of a nuclear
incident, whether alleged to be due, in whole or in part to the
negligence or otherwise of the Seller or its suppliers.
