Plasma Resonance Flame Detection

Stackmatch Flare Ignition Inc.sma Resonance Flame Detection method has many of the positive features of the flame ionization rod, without the problems identified with grounding due to the presence of liquids, moisture or false signals due to flame movement.

The reliable and consistent confirmation of pilot and/or burner flame plus related costs, is a significant concern to users. The common methods used are thermocouples and/or optical devices. Thermocouples have been known to fail due to thermal cycling and exposure to thermal shock conditions due to rain or liquids. Optical flame detection devices in many cases require regular maintenance to ensure the lens is clear for optimum operation.

This method utilizes the modulating impedance within the Flame Plasma generated as a result of the numerous chemical reactions occurring during the combustion process. Variations in the plasma impedance result in an electrical signal that is representative of the flame. This method can be applied to any applications where it is necessary to accurately evaluate the presence or absence of a flame.
