Abstract
An charge element disposed proximate to a combustion reaction is caused to carry a voltage while also being prevented from arc-discharging or arc-charging to or from the combustion reaction, by a current limiting element in electrical continuity with the charge element.
Claims23
A combustion system, comprising:
- a charge element configured to be disposed proximate to a combustion reaction, the charge element including a plurality of electrode elements;
- an electrical node configured for electrical continuity with the charge element;
- and
- a plurality of current-limiting elements disposed to convey the electrical continuity from the electrical node respectively to the plurality of electrode elements and to limit current flow therebetween;
- wherein the plurality of current limiting elements are configured to collectively conduct, between the electrical node and the plurality of electrode elements, a total electrical current that is greater than an amount of current carried by an electrical arc, and to individually limit current in each of the electrodes to less than an amount of current carried by an electrical arc;
- whereby maintaining electrical coupling between the combustion reaction and the plurality of electrode elements prevents an electrical arc from forming between the combustion reaction and the plurality of electrode elements.

A method for electrically interacting with a combustion reaction, comprising:
- supporting a plurality of charge elements or plurality of electrode segments proximate to or in contact with a combustion reaction;
- coupling the plurality of charge elements or plurality of electrode segments to an electrical node through a corresponding respective plurality of current limiting elements;
- configuring the plurality of current limiting elements to collectively conduct, between the electrical node and the plurality of charge elements or the plurality of electrode segments, a total electrical current that is greater than an amount of current carried by an electrical arc, and to individually limit current in every charge element or electrode segment to less than an amount of current carried by an electrical arc;
- applying electricity to at least one of the combustion reaction or the electrical node;
- and
- maintaining electrical coupling between the combustion reaction and the plurality of charge elements or plurality of electrode segments while the plurality of current limiting elements prevent an electrical arc from forming between the combustion reaction and the plurality of charge elements or plurality of electrode segments.
