The invention can be used in plasma energy complexes while burning or coal-water mixtures. An induction plasma burner comprises a body with a nozzle, inside of which a plasmatron is installed, the plasmatron is a tube made of electrically insulation material forming inside a plasma generating chamber connected to a fuel mixture connecting branch, inductor turns are located inside the tube walls. The burner body has an oxidizer input pipe and a cooling system. The plasmatron tube with inductor turns and plasma-generating chamber are made as a toroid, the inductor turns are in spiral laid around the plasma-generating chamber hollow tubular conductor made from heat-proof conducting material, for example, carbon-carbon composite forming the internal spiral channel for cooling mixture passing. A protection burner case forms with the plasmatron tube a hollow for passing oxidizer, the inner cross section of toroid is provided with a disk-shape dielectric refractory partition. The pipe for fuel mixture output is to the fuel supply input and in the same way is made of dielectric refractory material and has contact holes connected to the nozzle. The technical result of the invention is raising efficiency of high-frequency magnetic field induced in the plasmatron. |
