Industrial Boiler Tuning

Boiler combustion services


Tuning industrial boilers for optimal efficiency.

Boiler tuning is an important maintenance item used to adjust the air to fuel ratio in the boiler and achieve maximum combustion efficiency - the measure of how effectively the heat content of a fuel is transferred into usable heat.


Beyond ensuring long term equipment life and operational reliability, highly efficient boiler systems can mean significant bottom-line cost reduction, NOx reduction and fuel savings. Boiler tuning should be performed each year to maintain peak efficiency.


A regular boiler tune-up provides an opportunity to verify current boiler operating performance and establish a baseline for optimization adjustments, such as fine-tuning the amount of excess air available to completely burn the fuel. Using the optimal amount of excess air minimizes heat loss up the stack and improves combustion efficiency. It is not uncommon for boilers to operate at greater than desired excess air levels, resulting in in heat lost due to the increased flue gas flow, which lowers the overall boiler fuel-to-steam efficiency.


Two primary indicators used to measure combustion efficiency are flue gas oxygen (or carbon dioxide) composition and stack temperatures.


  • Flue gas composition indicates whether the fuel is being burned as efficiently as possible.
  • Flue gas temperature indicates how effectively combustion heat is being transferred to the boiler water.


Rule of thumb:
boiler efficiency can be increased 1% for each 15% reduction in excess air or 40°F reduction in stack gas temperature
