Informative reading: Avoid an Outage with New Hydrogen Leak Detection Technology

Maintenance of hydrogen-cooled generators is critical for the safe an efficient operation of a power plant.  The GF343 is an optical gas imaging camera that lets you see CO2 leaks quickly, easily, and from a safe distance.

Finding and repairing hydrogen leaks from the cooling system is one aspect that can require exhaustive searches on components, valves, fittings, or other locations.  Traditional methods for hydrogen leak detection tend to be unreliable at finding the source of the leak and better at finding a general area where hydrogen is present.  The advent of optical gas imaging cameras has improved the efficiency and performance of leak detection a great deal. With the addition of a dedicated thermal imaging camera for CO2 leak detection, utilities now have a way to efficiently find hydrogen leaks while using CO2 as a tracer gas.  The operation of an electric power generator produces large amounts of heat that must be removed to  maintain efficiency.  Depending on the rated capacity of the generator, it might be air cooled, hydrogen cooled, water cooled, or in the largest capacity generators, a combination of water for the stator windings and hydrogen for the rotor.  Hydrogen cooling offers excellent efficiency thanks to low density, high specific heat and thermal conductivity. However, hydrogen is highly combustible when mixed with air and can be dangerous if the concentration level builds in an unwanted area. Turbine generators will leak some hydrogen during normal operation and rely on proper ventilation to keep the hydrogen levels from being a safety and explosion risk.  Thus, hydrogen gas safety is critical for power plant operators.

FLIR'S 2019 UK Optical Gas Imaging Workshop

Following the huge success of FLIR'S Optical Gas Imaging Workshops carried out overseas, we're happy to announce FLIR will be running one here at Acutest's headquarters in Newcastle-under-Lyme, Nr Stoke, this spring!

FLIR'S Steve Beynon will be giving an overview of Optical Gas Imaging (OGI) Technology, how it works, applications and real life examples of OGI scenarios.

Workshop Agenda:

  • What is Optical Gas Imaging (OGI)?
  • How does it work?
  • Examples of gases seen
  • Real life scenarios - Thermographers using OGI
  • Safety considerations including hazardous areas
  • Environmental regulations
  • Standards
  • Get hands-on with OGI!

FLIR models featured in this workshop:

Perfect for the following sectors:

  • Utilities
  • Manufacturing
  • Oil & Gas


  • Natural Gas Supply Chain
  • Gas Transmission
  • Biogas Anaerobic Digester Users
  • Automotive Manufacturing

Location: Acutest Century Road, High Carr Business Park, Staffordshire, Newcastle-under-Lyme (Nr Stoke), ST5 7UG

Date: 2nd of May (10am to 2pm with registration starting from 9:40am)

Refreshments will be provided.

There will be limited spaces available so to avoid disappointment book today.

We look forward to seeing you soon!
