Fan mill plasma burner with oscillating nozzle

Abstract

This invention discloses a fan mill plasma burner with a swing nozzle, comprising a nozzle adjustment assembly, a coal inlet pipe, a plasma generator, a burner body, a connecting cylinder, and a swing nozzle. The swing nozzle includes a fixed baffle and a swing plate. The nozzle adjustment assembly includes two sliding seats, two first connecting rods, two second connecting rods, a rotating block, a moving block, a first drive mechanism, and a second drive mechanism. One of the fixed baffles has an arc-shaped slot, and the rotating block is rotatably mounted on the fixed baffle. Each sliding seat has a first sliding groove, and one end of each first connecting rod is hinged to the rotating block, while the other end is slidably engaged with the first sliding groove. One end of the second connecting rod is hinged to the first connecting rod, and the other end is rotatably connected to the moving block. The rotation output end of the first drive mechanism is connected to the rotating block. The movement output end of the second drive mechanism is connected to the moving block. This invention can reduce local slagging and overheating in the furnace and improve the uniformity and stability of combustion.
