Abstract
The utility model relates to an efficient clean-combustion multi-powder cyclone burner, which comprises a feeding pipe, an ignition device, a secondary air distribution device, a powder combustion chamber, a PLC burner control device and a ceramic spray pipe. The tail end of the feeding pipe is connected with the ceramic spray pipe. The ceramic spray pipe is positioned at the center of the burner. The outside of the outlet end of the feeding pipe is provided with the secondary air distribution device. The powder combustion chamber is arranged inside the burner. The burner and an external PLC control device are connected together. According to the utility model, due to the adoption of the PLC control device, the data of parameters, such as the operation load variation of a boiler, the oxygen content of flue gas, the negative pressure in a hearth and the like, are collected, compared and calculated so as to realize the automatic operation of a combustion system and the automatic adjustment of a load. Due to the adoption of an adjustable volute cyclone air inlet mode, the flame shape can be conveniently adjusted and the efficient combustion is realized.
