We offer upgrades and replacements of old or obsolete ABB / Bailey actuators and positioners with an easy cross-over conversion program for new generation ABB models and required mounting adapters.

Fuel savings:

According to Electric Power Research Institute calculations; improving excess O2 control 0.5% with tighter FD/ID fan damper positioning can result in 0.15% heat rate improvement.

For a 500 MW coal-fired boiler, that can result in $120,000 per year in fuel savings!

Benefits of improved damper control

  • Improved heat rate – Old damper actuators do not respond quickly or accurately, resulting in inefficient combustion with poor heat rate and undesirable emissions, upgrading or replacing your damper actuators improves these and can result in immediate fuel savings.

  • Emissions reduction – Upgrade or replace old damper actuators to avoid expensive fines and meet EPA directives.

  • Reduced maintenance costs – Upgrading or replacing old damper actuators reduces maintenance and associated costs in terms of spares, time, and unplanned shutdowns.

  • Reduced operating costs – Upgrading or replacing old damper actuators saves fuel costs by reducing process variability
