Abstract

A burner includes a flame sensor configured to detect at least one of permittivity, capacitance, or resistance across a flame region. The permittivity, capacitance, or resistance is used to determine the presence or absence of the flame in a combustion system. A combustion system supports a combustion reaction. The combustion system utilizes a combustion sensor, and optionally a plasma generator to stabilize the combustion reaction. A controller receives sensor signals from the combustion sensor and controls the plasma generator to stabilize the combustion reaction responsive to the sensor signals. The plasma generator stabilizes the combustion reaction by generating a plasma.
