Considerations When Upgrading Boiler Plant Controls

Boiler plant upgrades don’t necessarily mean building an entirely new plant and installing new boilers.  In the past several years significant advancements have been made in controls and burners, allowing for far greater efficiency and turndown capacity.  For many facility managers, upgrading controls breathes new life into aging boiler plant systems.

A recent report from the US Department of Energy states boiler efficiency can be increased in three ways: replacing with new boilers, replacing burners or installing a combustion control system.  The same report stated, “While installation of a new boiler or replacement of the burner can lead to the greatest efficiency gains, the higher costs associated with these measures typically leads to longer payback periods than installing a combustion control system.”

Older mechanical sensors and linkage are simply outdated technology and are far less efficient than today’s controls.  In addition, retrofitting existing boilers and infrastructure is usually a viable and lower-cost option, compared to complete boiler system replacement.  Best of all, the immediate energy savings leads to a fast return on investment – often less than a year.
