DOWNFIRED SALT / CAUSTIC INCINERATOR
Downfired Incineration Systems typically treat wastes containing inorganic salts
(NaCl, Na2SO4, Na2S), organic salts (acetates and oxalates of alkali metals), caustic
liquids, and non-combustible solid materials. Downfired Incineration Systems earn their
namesake from vertically-oriented burners located at the top of the incinerator that fire
downwards. This design promotes longer refractory life and accumulation space for any
non-combustible solids contained in the waste gas. Many Downfired Incineration Systems
employ additional equipment such as baghouses, multi-clone filters, and electrostatic
precipitators to provide enhanced particulate removal capability.
