Why is it important to get low NOx burners tested?

Like all industrial equipment, low NO_x burners need consistent monitoring to ensure the emissions and pressures experienced by the machine are safe.

Luckily, with the help of Testo instruments, this is something that any business using these burners can manage themselves, keeping you in control while your staff stay safe.

What should you look out for?

The first thing that should be checked with regards to these burners is the amount of NO_x (nitrogen oxides) being emitted in their operation. As the whole point of these systems is to power boilers with less NO_x emissions than their traditional counterparts, excess fumes mean the system is not running as intended.

This compromises efficiency and safety, and is not acceptable in a workplace. As well as the environmental concerns, staff health can be impacted if the gases are breathed in too frequently at high concentrations.

One of the reasons for high NO_x readings in these cases is a lean fuel mixture. This means that either there is not enough fuel to properly fill the combustion chamber, or too much air is being added to the fuel in the process. If your boiler is producing a high NO_x reading, it’s worth making sure that it is being fueled correctly.

Irregular NO_x readings could also indicate that the exhaust gas recirculation system is not functioning correctly, meaning one of the hoses or valves in the system could be faulty. In any case, checking these parts of a burner should be standard maintenance as they are responsible for some receiving high pressure gases. If one of them fails completely, it could spell disaster.

Finally, if a burner is overheating, it can result in higher NO_x readings than normal. If you suspect this is happening, it’s imperative that you solve the problem as soon as possible. Overheating components in any installation are a massive danger, as they compromise the structural integrity and safety of the entire machine.

Can Testo help?

Of course! With years of experience in the industry, our instruments are more than prepared for the workplace, offering dependable performance to keep your staff and equipment safe.

The key feature of our products is that they are digital, allowing for quick and clear readings that eliminate any need for working out equations. When you’re testing a boiler to see if it’s about to overheat, there’s no time to muck around with calculations.

Thanks to the automatic sensor, the Testo 340 combines digital functionality with the ability to read gas levels at any concentration. This allows it to accurately measure leaks of any size.
