Claims18
An apparatus for treating a gas stream, comprising:
- a DC plasma torch configured to generate a plasma flare from a source gas when energized by a source of electrical energy;
- a flow regulator configured to regulate the flow rate of the source gas supplied to the DC plasma torch to be energized;
- and
- a power control configured to control the power of the DC plasma torch by selective control of the flow regulator.
