Boiler Combustion Tuning
Combustion tuning industrial boilers is important to maintain efficiency and safety. Depending on the age and control strategy, boilers should have a combustion test performed at least once every two years. Companies that have their boilers tuned yearly do this for a very good reason. They know that their boiler consumes a great deal of fuel and the cost to have it tuned can be easily saved in the fuel it uses.
from Transmitter Calibrations:
“Having an oxygen trim loop is a plus and one can always tell how far a boiler has gone out of tune by how much the oxygen trim has to compensate to bring it back. To see if your fully metered boiler has shifted from the original tune look no further than the oxygen trim loop and how far it shifts the output from 50%. If the entire operating range with everything in auto has the oxygen trim loop output at or very near 50%, you have a fine running boiler tune. If the oxygen trim loop output has to swing all the way down or up, it is recommended to have a qualified boiler field service engineer perform a tune or troubleshoot and calibrate the oxygen transmitter.”
Collins Combustion will perform a combustion tune and provide detailed data that can be a great reference for troubleshooting. We not only provide O2, NOx and CO but also record the following if access ports are available:
-Supply Gas Pressure
-Gas Pressure at Burner
-Windbox Pressure
-Furnace Pressure
-Air Flow
-Forced Draft Fan VFD Speed
-Gas Flow
-Steam Flow
-Drum Pressure
-Firing Rate
-Loop Outputs
-Tuning Parameters Entered
With years of experience programming PLC Combustion Control Systems, our understanding of how a program works helps us perform a very thorough tune. Quite frequently we have customers comment that a previous vibration is gone and that they have never had their boiler run so good. We offer our services for the US and Canada 24/7 and will travel international as well.
