The invention discloses a compound multifunctional DC burner, containing in turn performance adjusting wind spout III, secondary wind spout, coal powder horizontal shade primary wind spout, performance adjusting wind spout II, coal powder horizontal shade primary wind spout, and secondary wind spout, there is a performance adjusting wind spout I on the against-fire side of the primary wind spout, the axes of the primary wind spout and performance adjusting wind spout III drift off that of the secondary wind spout and lean to the facing-fire side, and the performance adjusting wind spout II folds toward water-cooled wall from parts of the runners of the secondary wind spout. It has advantages of wide coal applied range, preventing water-cooled wall from clogging (coking), high-temperature corrosion resistance, low load stable combustion, low-nitrogen oxide discharge, self-adjusting performance, etc.
