FLIR Systems’ GF343 optical gas imaging (OGI) camera can be used to detect leaks in hydrogen-cooled turbogenerators.

FLIR GF343 Optical Gas Imaging camera

Hydrogen-cooled generators, used in power stations for electricity production, are carefully monitored for their hydrogen concentration for safe and efficient operation. There is a constant effort to monitor and maintain any leaks, not only for operational efficiency but also from a safety perspective, as concentrations of Hydrogen (four to 75 per cent) in air can be explosive.

Today, the power generation industry performs leak detection and repair (LDAR) of the generators during a shutdown period. This shutdown could be over a two- to three-week period with three to four days dedicated to LDAR. However, by adding a small concentration of CO2 (less than five per cent) as a tracer gas to the hydrogen, the generator will still operate at a safe and efficient level and the operator and maintenance teams will be able to monitor for leaks during full operation using a GF343 OGI camera.

In recent tests, the FLIR GF343 was shown to accurately visualise a small amount (~2.5 per cent) of CO2 tracer gas in the system when there was a leak, thus helping maintenance crews find and pinpoint leaks. Leak detection on hydrogen-cooled turbogenerators can now be performed under full operation, saving time and money by reducing shutdown time.

FLIR GF343 in detail

  • This OGI camera lets users detect and visualise CO2 leaks quickly, easily and from a safe distance.
  • Reliable, non-contact CO2 detection using the GF343 lets power plants prevent unplanned outages by allowing them to inspect equipment while it is still online in the course of normal operations.
  • The camera also helps keep operations safe while moving towards carbon-neutral capture and storage operations.
  • Optical imaging using FLIR GF-Series thermal cameras offers a number of benefits compared with traditional ‘sniffers’, because they scan a broader area more rapidly and in areas that are difficult to reach with contact measurement tools.
  • Infrared displays a leak as a plume of vapour in the infrared image. Once a leak is found from a safe distance, the user can utilise the TVA to quantify the concentration.

FLIR Systems specialises in technologies that enhance perception and awareness.  The company brings innovative sensing solutions into daily life through its thermal imaging and visible light imaging technology and systems for measurement, diagnosis, location and advanced threat detection.  Its products improve the way people interact with the world around them, enhance productivity, increase energy efficiency and make the workplace safer.

FLIR Systems has six operating segments – surveillance, instruments, OEM and emerging markets, maritime, security and finally, detection. Of these six, ‘instruments’ is of greatest interest to trade and industry and the second largest segment in the company’s portfolio. This division provides devices that image, measure and assess thermal energy, gases and other environmental elements for industrial, commercial and scientific applications.

These products are manufactured across five production sites, three in the USA and two in Europe; Sweden and Estonia.

A model to suit every application and budget
The options that FLIR Systems provides for measuring temperature and studying thermal performance have never been greater.  Not only does the company offer a huge range of models to suit all thermal application needs but the technology is also affordable and very easy to use.  Thermal cameras now come in various shapes, sizes and degrees of sophistication and FLIR continues to invest heavily in the development of new and complementary technologies to differentiate itself from competitors.

An important milestone in the development of thermal imaging has been the introduction of the FLIR Lepton® core, a micro longwave detector, the size of a mobile SIM.  This has allowed thermal imaging to be repackaged to meet the needs of an even wider audience and, in combination with another new technology called Infrared Guided Measurement – IGM™ – has led to the development of a range of test and measurement meters with imaging capability.

Another important growth area for FLIR thermal imaging is in continuous monitoring to assure quality and safety.  Through its introduction of discrete fixed mounted thermal cameras which are fully compliant industry standard plug-and-play protocols, FLIR Systems has provided industry with infrared machine vision which is instantly ready for quick and easy network installation.

Protecting assets and people from fire is an area for which thermal imaging is least known but, thanks to FLIR Systems’ development, it is now one of the most cost-effective methods available.  Its application flexibility and rapid return on investment present an attractive proposition for any site or safety manager.
