The importance of annual calibration for your flue gas analyser/combustion analyzer 

For many heating engineers, the flue gas analyser/combustion analyzer is vital kit; so much so, that most would have problems working without one. However, calibration and servicing generally require the engineer to send the analyser away for a while. That’s why, when the annual calibration date comes around again, some find themselves tempted to put it off, just for a while … 

Please ignore that temptation. It is absolutely vital to get your flue gas analyser calibrated every year, and failing to do so could cost you your job – or worse. Prompt annual calibration is simply not negotiable, and in this blog post we’ll explore the reasons why. 

Annual certification required 

A flue gas analyser is safety equipment and its accuracy may be – quite literally – a matter of life or death. The  sensors inside flue gas analysers react with the gasses they detect and degrade slightly over time. Compiled over the course of a years active use, the degradation can lead to inaccuracies in the readingsAdditionally, like any equipment, things can go wrong and parts can fail; that’s why all flue gas analyser manufacturers require an annual certificate of calibration, and the impact of not having one can be legally, financially and personally disastrous. 

Imagine, for example, that an accident has occurred and somebody or something has been harmed because your flue gas analyser failed to detect an issue. If that analyser was uncertified and had not been calibrated within the time period required (which would be easy to ascertain, since gas reports have the relevant times and dates printed on them), then you and/or your employer may be held criminally and civilly liable for this, having failed to exercise your duty of care to your client.  

That’s why, if your combustion analyzer is showing any signs of failure, or if your annual calibration is due, you need to book it in promptly. 

What about costs? 

Sometimes, engineers are tempted to put off calibration for fear of the costs. And yes, there may be charges involved due to damage or wear and tear: but what price do you put on safety (both the safety of the people you serve the security of your own job or business?) If cost is an issue, there may be ways to mitigate this. Manufacturers know that calibration is a recurring cost and some offer pre-pay options to make this easier to manage; some offer pre-pay options for parts as well. If you’re not sure whether this is the case for your device, it is worth talking to the manufacturer because the savings can be substantial. 

What happens during calibration? 

During its annual service and calibration, your flue gas analyser will be checked over and any components (for example, an oxygen sensor) will be replaced as required. A known concentration of certified test gas will be passed into the analyser and the instruments software will be adjusted to make sure it takes into account any drop off in sensor response and to ensure the analyser responds appropriately to all gases across the range of detection.  

Don’t wait – calibrate 

As you can see, calibration and any associated changes are vital to the functioning of your analyser, so you should never postpone or overlook your annual calibration: in fact, you must not use a flue gas analyser at all, once the previous calibration has expired. This applies however often (or not) you use it: the risks are the same.

Reset & Recalibrate – A Guide to FGA Calibration

Ensuring your flue gas analyser (FGA) is regularly maintained goes without saying, however the hows and whys take a little more digging into. This article breaks down the calibration process and highlights handy tips and tricks for maintenance and best practice. 

The Act of Calibration 

Calibrating an FGA involves checking the sensors to ensure accurate measurement of a known concentration of certified calibration gas. To do this, the reading needs to be adjusted to match the gas concentration through an initial sensor calibration of the new or existing unit.

Next up is a calibration drift – this is done using existing instruments to bring the reading back after the drift occurs. Measuring the amount of drift in the gauge is a chance to see how far into inaccurate territory it has moved, and rule out measurement errors moving forward. 

Regularity is key

Sensors degrade over time with each sensor having a different life span of optimum operation, whether it is an electrochemical, catalytic bead and infra-red sensors. Regular calibration raises the gain levels and brings the sensor back in line to avoid dangerous incorrect readings. 

Once the sensor reaches a certain point it cannot be brought back into the correct position and this is the time when a new sensor needs to be installed. 

Explaining the calibration procedure 

The first step of the process is to set the device to calibration mode. This feeds a test gas of a known concentration onto the sensors to see how they respond. The gain levels are adjusted within the sensor to match the readings to the concentration fed in whilst mitigating drop off. 

The new settings are locked into the device’s firmware and a calibration report is produced, creating a PASS or FAIL result. 

Best Practice Tips and Tricks

Here are some best practice recommendations to help you maintain your FGA.

  • Clear out the water trap regularly – moisture is a by-product of combustion and can get sucked into the FGA when a test is undertaken. Water damage is the primary cause of damage in flue gas analysers, so it is imperative to check, empty and replace the unit’s inbuilt water traps and filters to protect from this.
  • Purge the device in clean air before powering down – noxious gases are drawn from the flue and passed over the sensors to gain a reading. After a test is completed and the system closes down some of that gas remains trapped inside. This can cause corrosion damage and shorten the life of the unit, so purging in clean air prior to shut down is a must.
  • Take inside to protect from cold weather conditions – to lessen the chances of condensation build up and water damage within your FGA make sure to remove the unit from your van overnight. This also reduces the risk of theft. 
  • Use approved chargers with outputs tailored for target device – non approved chargers cause damage to the battery and lessen charge retention, or even impairment to the battery and IC chips of the device itself.  
  • Check the devices’ probes and connector pipes – any splits or cracks in the rubber house will cause incorrect readings. Performing periodic checks on your hoses to ensure they are in good operating condition is a useful habit.

Explosion hazards in inerted tanks and how to avoid them

Hydrogen sulphide (H2S) is known for being extremely toxic, as well as highly corrosive. In an inerted tank environment, it poses an additional and serious hazard combustion which, it is suspected, has been the cause of serious explosions in the past.

Hydrogen sulphide can be present in %vol levels in “sour” oil or gas. Fuel can also be turned ‘sour’ by the action of sulphate-reducing bacteria found in sea water, often present in cargo holds of tankers. It is therefore important to continue to monitor the level of H2S, as it can change, particularly at sea. This H2S can increase the likelihood of a fire if the situation is not properly managed.

Tanks are generally lined with iron (sometimes zinc-coated). Iron rusts, creating iron oxide (FeO). In an inerted headspace of a tank, iron oxide can react with H2S to form iron sulphide (FeS). Iron sulphide is a pyrophore; which means that it can spontaneously ignite in the presence of oxygen

Excluding the elements of fire

A tank full of oil or gas is an obvious fire hazard under the right circumstances. The three elements of fire are fuel, oxygen and an ignition source. Without these three things, a fire can’t start. Air is around 21% oxygen. Therefore, a common means to control the risk of a fire in a tank is to remove as much air as possible by flushing the air out of the tank with an inert gas, such as nitrogen or carbon dioxide. During tank unloading, care is taken that fuel is replaced with inert gas rather than air. This removes the oxygen and prevents fire starting.

By definition, there is not enough oxygen in an inerted environment for a fire to start. But at some point, air will have to be let into the tank – for maintenance staff to safety enter, for example. There is now the chance for the three elements of fire coming together. How is it to be controlled?

  • Oxygen has to be allowed in
  • There may be present FeS, which the oxygen will cause to spark
  • The element that can be controlled is fuel.

If all the fuel has been removed and the combination of air and FeS causes a spark, it can’t do any harm.

Monitoring the elements

From the above, it is obvious how important it is to keep track of all the elements that could cause a fire in these fuel tanks. Oxygen and fuel can be directly monitored using an appropriate gas detector, like Gas-Pro TK. Designed for these specialist environments, Gas-Pro TK automatically copes with measuring a tank full of gas (measured in %vol) and a tank nearly empty of gas (measured in %LEL). Gas-Pro TK can tell you when oxygen levels are low enough to be safe to load fuel or high enough for staff to safely enter the tank. Another important use for Gas-Pro TK is to monitor for H2S, to allow you judge the likely presence of the pryophore, iron sulphide.

Working together for safety at sea

Crowcon Detection Instruments is working together with Solent University’s Warsash School of Maritime Science and Engineering – all in the name of teaching engineering cadets, senior Merchant Navy officers, and Superyacht crews.

Solent delivers world-renowned yacht and powerboat design degree programmes, a suite of international maritime studies courses and a wide range of specialist support services for the maritime industry. It is also conducting a large number of research studies that make a real impact on industry thought leadership.

Their partnership with Crowcon makes good sense!  The marine environment is a dangerous one – and not just the more obvious hazards like high seas, storms, or rocks and coral reefs.  Confined spaces on ships, high-risk cargo, and on-ship processes all present potential gas hazards.

To keep mariners safe, gas monitoring equipment is essential.  Gas detection equipment requires specific marine environment testing and certification to ensure suitability to the extreme environments it operates in.  The European Marine Equipment Directive (MED) approval is internationally recognised. Gas detectors used by mariners onboard a vessel registered in an EU country must hold MED approval, and show the wheel mark to demonstrate compliance.

Crowcon has provided the university with demonstration T4 portable multi gas detectors.  T4 provides effective protection against the four most common gas hazards experienced in the marine industry, and is robust and tough enough to deal with the demanding marine environments.  T4 is ideally suited to help vessels comply with multiple SOLAS requirements which dictate the need for gas detection onboard vessels.

John Gouch, lecturer at  Solent University, said: “I have used Crowcon instruments in industry for many years, and know how reliable and trustworthy their gas detectors are. Since joining Warsash 18 months ago, I have been keen to ensure students understand the important part gas detection plays within the on-board safety system.”

“By using demo units of these detectors within our marine engineering courses, we can show the importance of gas detection in a marine environment to hundreds of seafarers and mariners, keeping as many people as possible aware and safe.”

Louise Early, Head of Marketing at Crowcon, said: “We’re really pleased with our partnership with Solent University.  By developing our relationship with training establishments, our safety message gets out to the people who will benefit most. We are always keen to learn from industry and this programme also offers Crowcon further insight into the way in which our equipment is used.”

Planning for shutdown season

Maintenance performed during a site shutdown often takes in gas detection systems, including checking expiry dates and calibration. For some, shutdowns also increase the use of portable and transportable monitors, as fixed systems are being maintained and extra personnel come on site to work.  Every year, around this time, we get a significant increase in calls about problems arising during site shutdown. Many of these could have been avoided with a little planning and forethought.
