The basic principle of plasma ignition technology of pulverized coal burner is to directly ignite pulverized coal with high-power arc. The ignition device uses a DC current (greater than) to initiate an arc through the contact of the cathode and anode under the condition that the medium pressure is greater than., and obtains a DC air plasma with stable power under a strong magnetic field. Its continuously adjustable power range is ~ and the center temperature can reach ℃. After the primary air powder is fed into the plasma ignition pulverized coal burner and separated into dense and light phases, the dense phase coal powder enters the center area of the plasma torch and ignites quickly within about 10 seconds, and provides a high-temperature heat source for the light phase coal powder, so that the light phase coal powder also Fires quickly, eventually forming a stable burning torch. The burner wall adopts air film cooling technology, which can cool the burner wall to prevent burning damage and slagging. Demineralized water is used to cool the electrodes and coils.
