Scrubber burner

A scrubber burner 10 comprises an inlet module 200 supplying waste gas to a burner module 100 and a guide module 300 to discharge incinerated waste gas. The burner module comprises a burner housing 110 and a porous cartridge (120, Fig. 7) surrounding a combustion area (S1, Fig. 7). A conduit 130 supplies cleaning gas to the porous cartridge to prevent powder being deposited onto an inner wall of the porous cartridge. The porous cartridge may comprise a porous plate (121, Fig. 7) with holes to guide cleaning gas in an inwardly radial direction. The inlet module may have a main inlet conduit 210, a cover inlet conduit 220, and a sub inlet conduit 230. The guide module may comprise a guide discharge duct 310 with an inclined surface (311, Fig. 7), and a guide member 320 connected to the burner housing. Discharge water may be supplied through a water flow passage (322, Fig. 7) and nozzle (324, Fig. 7). A nozzle assembly (140, Fig. 2) may supply fuel gas and an oxidant to the combustion area. The burner module may comprise a burner head 150 and a cooling member (160, Fig. 2).
