Have quality issues with your wood fuel? How Azwood addresses these challenges

We understand that from time to time quality issues can arise when using wood fuel or pellet fuel for commercial or industrial heating. Azwood is proud of the quality fuel we manufacture and takes quality issues with our wood fuel seriously.

The cause of quality issues

There could be a couple of things causing issues that might not actually be to do with the wood fuel itself.

01
Your boiler hasn't been regularly maintained or cleaned
This can cause a range of issues such as leaks, corrosion, system malfunctions and more.
02
Build-up of ash
Biomass combustion produces ash that, if not cleaned regularly, can build up over time and cause blockages which reduces efficiency and can even shut down the boiler.
03
Clinker in your boiler
Clinker is formed by burned or partially burned low-quality fuel. The impurities found in low-quality wood fuel will react at high temperatures melting into clumps and forming a solid residue. This can result in operational challenges.
04
Overheating
If the fuel feed rate exceeds the boiler's capacity, the temperature in the furnace may increase dramatically and can ultimately damage the boiler.
05
Incorrect sizing of wood fuel used
If the boiler isn't correctly sized for the fuel load, it can result in frequent cycling which can damage the boiler and lead to inefficient energy usage.
06
Control system failures
If the control systems of the boiler, like sensors and float switches, aren't working correctly, the boiler can shut down or fail to operate efficiently.
07
Using the wrong fuel type
It’s important to ensure the specification of the fuel you are using is manufactured and supplied within the strict criteria for your boiler. If your fuel is not performing, first check you are using the right fuel.

Sometimes what might seem like a quality issue, may actually be something else. It is good to gain an understanding of the fuel your using, where it is sourced from and if it is right for your boiler's specifications.
Understanding your fuel type
Getting the right energy output for your boiler can sometimes take a lot of fine-tuning to get the most out of your fuel. If you are having quality issues it may be that it’s not the fuel quality but in fact the fuel type.
