Abstract

PURPOSE: To generate stable plasma flame as well as make the control of plasma flame easier by supplying concurrently a high temperature gas to the central part and also a low temperature gas to the circumferential part as working gases for plasma generator.
CONSTITUTION: The path 5 for inert gas is formed around the outside circumference of the internal electrode 2. From the blowing tube 11, a high temperature combustion gas is sent to the electrode nozzle 1a through the outside of the heat-resistant electrode protective cylinder 12 and at the same time a low temperature gas, e.g., CO2, etc., is sent from the low temperature gas nozzle 10 to the outside of the high temperature gas flow, where a swirl flow of the low temperature gas passes through the nozzle 1a while wrapping the high temperature gas and also wringing up the tip portion of the gas, whereby forming the low temperature layer 9 covering the arc 3 and the high temperature boundary layer 8. Even outside the nozzle 1a, the low temperature layer 9 gives the plasma flame a pich effect to stabilize the plasma flame, and also the heat loss of plasma flame due to the nozzle 1a can be reduced to rise the heat efficiency.
