Enabling CO control with a single probe

Lamtec says CO Control takes a more empirical approach than oxygen trim, enabling combustion systems to get closer to stoichiometric conditions, whilst remaining safe. A self-adapting algorithm optimises the fuel:air ratio over the entire firing range. It ‘learns’ each point on the programmed combustion curve by reducing air to the point where CO is detected and then 'backing-off’ to a safe setpoint. 

Each 'learned' point has a lifetime of 8h, after which it is ‘learned’ again. This ensures that if external conditions have improved then the CO Control will readapt to compensate for this and increase efficiency. It is not uncommon for systems employing CO Control to run at 1% O2. As a rule of thumb, Lamtec says CO Control can generate an additional saving of up to 50% over conventional O2 trim systems.
