Method and apparatus for processing waste fluid

Patent ·
OSTI ID:5939078
The processing of combustible, partially combustible and noncombustible liquid waste at preferably high temperatures is claimed. The vertical combustion chamber is preferably round with liquids introduced from the top by spray nozzle or similar means and being treated as the liquid falls. Heat for preheating or processing comes from a number of flat flame radiation type burners addressing the falling liquid mostly by radiation heat. The number and arrangement of the auxiliary burners depends on the liquid to be processed and the furnace capacity. The auxiliary burner type and arrangement prevents flame impingement by the falling liquid. During the processing of certain liquids, the falling liquid will be totally surrounded by flames, from the top of the combustion chamber to a point at which no more processing is required. The discharge gases exit at the lower end of the combustion chamber and are beneficially utilized. For maximum efficiency, the liquid is air preferably air atomized. During processing of combustible liquids, the auxiliary burner fuel will be shut off while the combustion air of the auxiliary burners is left on providing combustible air for the waste liquid to be processed. Certain furnaces may be provided with a multiplicity of feed nozzles to provide means for simultaneous introduction of different types of liquids into the combustion chamber, such as combustible liquids through one nozzle, partially combustible liquid through another nozzle, and still other types of liquids through other feed nozzles.
