Boiler Calibration

While boilers may not generate your facility revenue, they certainly can cost you money when they do not perform properly.

Boilers are often a forgotten piece of equipment until they are down.


We offer yearly or quarterly calibrations to ensure the controls and instrumentation are all calibrated and working properly.

Why are calibrations important?

NOx curve durring tuning

  • Reduced down time, improved reliability
  • Optimum combustion efficiency, lower fuel costs
  • NOx and CO permit limit tuning
  • Verification of safety functions

There are two major parts to boiler calibration.

  1. Field device calibration
  2. Combustion Test and Tune

Field device calibration       

This ensures the field devices are working correctly and are accurate.

Over time field devices may become stuck, damaged or just break. Device calibration ensures the device operates and performs properly

Combustion Test and Tune

The boiler is operated from low fire to full fire and the firing curve is adjusted as needed

This helps improves reliability, efficiency and verifies air permit limits are met.

Combustion Tuning

Combustion tuningcan improve overall boiler efficiencies and improve boiler reliability

When the combustion controls are properly tuned to the plant operation, unexpected shutdowns are reduced or eliminated.

In addition to calibrating the field devices, ACC also tunes the boiler controls.  Boiler tuning is performed from low fire to full fire conditions.  The following is done to ensure the boiler control systems can provide reliable operation and operate at peak performance:

Equipment Startup


Shouldn’t the person responsible for system design and programming be available for the start-up?  We think so too!!


Applied Control Concepts provides startup assistance for all the control systems we design and configure.  This greatly improves the startup experience for the customer and ensures the system is operating properly.

The boiler house is the heart of any process plant.  Loss of steam production can cause reduced throughputs or even unscheduled outages.  It is critical for the boiler house to perform as reliably and safely as possible.


How much revenue does your facility lose when fired equipment is shutdown unexpectedly?  How long does it take to restore process conditions once your fired equipment is back online.  Often a regular manitance plan can prevent these outages.   


Chances are there is no larger single fuel user in your plant than the process boiler.  Increases in burner combustion and thermo efficiency can significantly improve the bottom line of your facility.


Applied Control Concepts offers several combustion related services to improve your bottom line.  Often these services can be performed on the equipment while in operation, minimizing process upsets.
