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.
Claims72
A combustion system, comprising:
- a charge element configured to be disposed proximate to a combustion reaction;
- an electrical node configured for electrical continuity with the charge element;
- and
- a current limiting element disposed to convey the electrical continuity from the electrical node to the charge element and to limit current flow between the electrical node and the charge element.
