1. Honeywell Fuel/Air Ratio Control System
Electronic Linkageless
Combustion Control

2. Lets imagine a combustion curve with mechanical linkages
What would a curve without mechanical linkages but with high precision motors look like?
All this amounts to:
The minimum modulation point can be lowered
More firing rate segments can be added to improve the curve

4. Four key factors involved:
Honeywell -provides control expertise and support to the other three entities.
Distributor -provides sales force and potential customer market search.
Integrator -provides boiler technical expertise and implementation.
End User -provides the necessary information.
