Hog Fuel Moisture


Having the correct hog fuel moisture levels of raw material in-fed to the boiler is a critical component of the combustion process.

The IR-3000 hog fuel moisture transmitter provides instant moisture content of the material being conveyed, allowing the operator to blend raw material to precise moisture levels required for efficient combustion.

With the help of industry partners and 40 years of knowledge and experience, MoistTech has developed a hog fuel moisture sensor that is ideally suited to measure the moisture levels during the combustion process.


By mounting the hog fuel moisture transmitter several inches above the conveyor will allow the user to continuously monitor the process and can control the hog fuel moisture content either manually or automatically in the combustion process.

The IR-3000’s unique feature is that it is able to monitor the process even with small gaps in product flow without impacting the accuracy.


Dust from the hog fuel product is not normally a problem. However, in extreme dusty environments, we recommend the installation of an air purge system to prevent the accumulation of material on the sensor’s window.

Benefits of Hog Fuel Moisture Testing

  • Improved Product Quality
  • Lower Energy Costs
  • Reduced Start-up Times
  • Less Waste
  • 100% Product Inspection
  • Less Downtime

MoistTech is very experienced with the hog fuel moisture sensing requirements in the combustion process in boilers using forest products residue. Our sensor calibrations, measurement wavelengths, algorithms and sensor optical requirements are pre-set at the factory. Typical accuracy is about ±0.2% moisture. Typical analog range is 0-75% moisture. The outputs can be adjusted to optimize PLC or recording requirements.
