Maximize the combustion efficiency of the burner! Air-fuel positioner enabling low O₂ operation.
The "FAPN Air-Fuel Positioner" is an electronic version of the traditional mechanical linkage cam mechanism used for combustion control in burners for boilers and industrial furnaces. It maximizes the combustion efficiency of the burner and enables operation at a low air-fuel ratio (low O₂). It takes a combustion load signal (4-20mA DC) as input and converts it into an optimal function (piecewise linear). Based on this function, it creates a curve that determines the optimal opening of the burner’s fuel valve and air damper to achieve the best air-fuel ratio, and controls accordingly. 【Features】 ○ Energy-saving ○ Low-cost microcontroller control ○ Accurate and easy operation for air-fuel ratio setting ○ Maintenance-free combustion adjustment ○ Monitoring function during operation For more details, please contact us or download the catalog.
