THREE INFRARED TEMPERATURE
MEASUREMENT SYSTEMS
FOR SULFUR REACTORS AND OTHER HIGH TEMPERATURE FURNACES
COMPLEX PROCESSES
Optimal operation of your Sulfur
Recovery Unit (SRU) requires measurement
and control of a complex sequence
of processes. Particularly important is
control of the reaction furnace temperature
to prevent damage to the refractory
at high temperatures and ammonium
salt plugging the converters at low
temperatures.
Those installations that use the reaction
furnace to incinerate waste gases
such as ammonia and hydrocarbons
must maintain an adequate temperature
to assure their destruction. Advanced
processes such as O2 enrichment
normally involve still higher temperatures
and demand close monitoring.

Mikron E 2 T applies sophisticated
infrared technology to the solution of
your furnace temperature measurement
requirements.
Mikron E 2 T has designed the PULSAR
family of three detection systems for
continuous and instantaneous measurement
of Refractory Temperature
(RT), Gas Temperature (GT) and
Integrated Temperature (FF) in the
vessel away from the heat, vibration
and corrosive gases. Each system
allows visual inspection of combustion
processes, refractory cure-out and preventative
maintenance while the vessel
is pressurized and fully operational.

SELECT AND INSTALL SYSTEMS T
Selection Criteria
Over 350 refineries, gas plants and petrochemical companies with over 1250 installations world-wide have
looked to E 2 TECHNOLOGY for accurate infrared (IR) temperature data. When you install Mikron E 2 T’s
Refractory Temperature (RT), Gas Temperature (GT) and Integrated Total Temperature (FF) IR thermometers,
you are investing in proven experience, superior performance and ultimate cost savings.
PROVEN EXPERIENCE
For a quarter of a century the energy industry has used Mikron E 2 T pyrometers in sulfur reaction furnaces,
spent acid plants, CO boilers and sulfur burners. Mikron E 2 T listens when industry speaks, and when clients
asked us whether we could manufacture furnace temperature measurement systems with multiple capabilities,
we accepted the challenge.
SUPERIOR PERFORMANCE
Industry wanted the capability to choose refractory, gas or integrated temperature measurement
and not simply accept a single temperature of unknown origin. Mikron E 2 T, utilizing SRU test
facilities, designed three separate models to meet this request.

Industry wanted systems designed for air and higher temperature oxygen-enriched reactors instead of
generic thermometers with limited temperature spans of 1000°C. Mikron E 2 T increases the range of its
sulfur reactor models to 900°-3500°F (480°-1925°C).
Industry wanted a simple but rugged monitoring system with cooling capabilities able to
withstand continuous exposure to corrosive gases and temperature extremes. Mikron E 2 T
builds monitors with heavy-duty swing-out fixtures and cooling cavities.
Industry wanted an explosion-proof housing as standard without expensive X and Y purge additions.

Industry wanted to visually see what the IR thermometer was measuring rather than guessing
on what you are focusing. Mikron E 2 T provides sight-through optics for viewport and furnace
viewing.

For Sight-p
Industry wanted to easily clean the window and clear the viewport of debris during operations without
waiting for a shutdown to resume thermometer readings. Mikron E 2 T includes a removable viewport
window and a clean-out probe assembly.
Industry wanted to safely field verify the IR thermometers during full operations instead of
depending upon dedicated thermocouples that burn out. Mikron E 2 T includes a thermocouple
probe assembly for verification and cure-out operations.

COST SAVINGS
Industry required enhanced capability systems at reasonable prices. Rather than introducing a basic generic instrument and
then adding various required expensive accessories, Mikron E 2 T introduces complete systems at lower cost with a choice
of refractory, gas, or integrated total temperatures. Well-designed superior performing IR systems do not need to cost more,
especially if you listen when industry speaks.

Installation Principles
Utilization of the different temperature measurement systems depends upon the feed gases and burner
design of the reactor. If you burn simple acid gas with combustion air, the FF Integrated Total Temperature
System should be installed two-thirds of the way downstream from the burner to the waste heat boiler. If there
is a checker wall or choke ring, installation at Locations 2 and 3 are recommended. When you are using your
reactor to destroy ammonia and/or other gases such as BTEX, it is essential that destruction temperatures
be achieved. To assure incineration, the FF Integrated Total Temperature System or the GT Gas
Temperature System should be installed at Locations 2 and 3.

With oxygen-enrichment, refractory integrity becomes critically important. Burner design and location become
paramount in determining the placement of the IR thermometer. The RT Refractory Temperature System
should be installed aimed at the area where the designers anticipate the highest refractory temperatures. For
example, Location 1 is recommended for checker wall protection and Location 4 for tube sheet monitoring.
Temperatures at the tube sheet are especially critical since the ferrules and ceramic tube-to-metal junctions
may face potential excessive temperature excursions as a result of oxygen-enrichment operations.

MOUNTING TO FURNACE
The PULSAR Model M7000SR should be mounted on the horizontal diameter (no greater than +35°) perpendicular
to the vessel sighting on refractory, or adjacent to the burner sighting on the checker wall or tube sheet.

The SOF-8 Swing-out Fixture mounts to a 3 inch 150 or 300 pound valve connected to the furnace via a spool
with purge connection. Minimum purge rates for downstream and viewport are 10 SCFM and 1 SCFM respectively.
The PULSAR’s housing includes a cavity for water or vortex air cooling when ambient temperatures
exceed 125°F (50°C). Flex lines should be used for power input and signal output.
