Abstract
A combustion system is provided, in which respective waveforms are applied to each of a plurality of electrodes positioned in a combustion volume, producing periodic electric fields between pairs of the electrodes. A safety circuit is configured to reduce or eliminate danger by grounding each of the plurality of electrodes or otherwise driving each of the electrodes to a safe state upon detection of a safety condition.
Claims19
-26. (canceled)
An apparatus for supporting and controlling a combustion reaction within a combustion volume, comprising:
- an electronic controller including an input terminal and a plurality of output terminals, the electronic controller being configured to produce, at each of the plurality of output terminals, a respective modulation waveform corresponding to a voltage modulation pattern at a respective one of a plurality of electrodes positioned proximal to a burner, and further configured to receive a safety signal at the input terminal;
- and
- a safety circuit configured to drive the output modulation waveform at each of the plurality of output terminals to a safe state responsive to a safety condition signal at the input terminal terminal.
-47. (canceled)
A method, comprising:
- supplying a respective voltage modulation pattern to each of a plurality of electrodes positioned proximal to a burner in a combustion volume;
- receiving a safety condition signal;
- and
- upon receipt of the safety condition signal, driving each of the plurality of electrodes to a safe state.
