Infra-View® Industrial Infrared Boiler / Furnace Thermometers
Infra-View Remote Infrared Temperature Sensing
lnfra-View Infrared Thermometers are remote sensing infrared detectors that are permanently flange mounted on any port, door or penetration into the boiler or furnace. The Infra-View patented design is supplied with a rugged protective cooling jacket that is factory assembled and pre-piped with an air cooler, purging and filtering system designed to work in most severe service environments. Customer supplied compressed air and two wire shielded signal cable is all that is necessary for operation when integrated in a 4-20 mA signal loop supplied from a DCS, digital or analog recording device. The lnfra-View infrared "non-contact" sensor monitors flue gas temperatures in the boiler or furnace ranging from 250°F to 3,000°F (higher end temperature available).
Principle of Operation
The lnfra-View sensor detects the heated C02 gas created in a boiler or furnace as a byproduct of the combustion process when fossil fuels are burned, such as coal, natural gas, oil, lignite and orimulsion. The infrared spectral response of the lnfra-View sensor is preset specifically to detect C02 infrared energy by using a thin film thermopile with a spectral filter designed to block out all other wavelengths of infrared emissions. Since the Infra-View detector is sensitive to only the hot C02 gas spectrum, It can measure the average, high or low temperature of the C02 gas directly within the field of view as it is heated within the specified temperature range.
Infra-View® Performance & Control Applications
Startup Temperature: Monitor ramp-up temperature for steam and power generation.
Process Control: Measure operating temperature of petrochemical furnaces and boilers for enhanced operation and efficiency.
Fluidized Bed Boilers: Monitor bed and flue gas temperatures. |
- Waste/Refuse Incinerators: Monitor compliance temperatures for incineration of toxic wastes at 1800°F.
lnfra-View can be certified to NIST standards.
- High Temperature Alarm: Monitor highest temperature and maximum load condition for most efficient operation.
- Furnaces: Measure ambient furnace gas temperature for improved operation and performance.

High Pressure Heat Exchanger Tube Plug
with Patented Hex Drive Capture System
There is a New, Easy Way to Seal Leaking Tubes!
The TORQ N’ SEAL® Heat Exchanger Tube Sheet Plug is a solid one piece plug that can be inserted into the tube sheet of a leaking tube and expanded with a standard 3/8" drive torque wrench. The plug will expand approximately 30 mils (.030") to provide a positive mechanical contact seal. The TORQ N’ SEAL® Heat Exchanger Plug can be used in high or low pressure applications such as feedwater heaters, moisture separator reheaters, preheaters, condensers, coolers, fin-fan coolers or any other tubed heat exchanger.
-
Positive sealing in excess of 6500 PSI is achieved without special tooling or personnel training.
-
Plug can be inserted to any depth of the tube sheet in order to avoid severely corroded areas on the tube sheet face.
-
Design enables rapid implantation and fit into tight areas adjacent to the tube sheet/shell joint interface, baffle plates and internal dividers.
-
One piece design enhances sealing characteristics by eliminating second potential leak path common to design found in two piece plugs.
-
Wide sealing area contact zone ensures a positive seal while the gradual and symmetrical torque expansion eliminates thermal and mechanical shock to the tube sheet, commonly found with welding, impact due to hammering of tapered pins, and explosive insertion methods.
-
Exclusive design allows installation of plugs at the face and back side of the tube sheet in order to prevent intrusion of shellside corrosives. With single plugging techniques accomplished on the face of the tube sheet, corrosives can enter the void created in the tube sheet, thereby exacerbating erosion and corrosion of the tube sheet ligaments
-
TORQ N’ SEAL® Plugs are available to meet Nuclear ASME
Sec. III or ISO 9002 QA specifications.
TORQ N’ SEAL® ...how it works!
The TORQ N’ SEAL® Plug is snapped onto the hex capture driver and inserted into the
tube ID, ensuring that the serrated sealing area is within the tube sheet. Applying the initial torque to the driver engages the anti-spin eccentric cam, locking the plug into the tube ID, thereby providing a torsional resistive force. As additional torque (in. lb.) is exerted, the drive screw threads into the plug body, pressing the tapered expansion ferrule into the reverse taper of the plug. These tapered surfaces combine to generate an enormous radial expansion force, swaging the serrated sealing area into the tube wall. A positive mechanical contact seal in excess of 6,500 psi is created.
