Oxygen control system

A standalone unit, the Lumec automated oxygen control system measures flue gas excess oxygen and constantly adjusts fuel flow to achieve a user-selectable set point. The control valve is installed in a boiler’s existing gas train. The oxygen control system compensates for changes in combustion air temperature and humidity, varying gas combustion, imprecise controls, dirty filters and loose linkages.
