METHOD AND DEVICE FOR BURNING OF MATERIALS, CONTAINING NOBLE METALS Russian patent published in 2010 - IPC C22B11/02 F27B5/00 C22B7/00 F23G5/27 

FIELD: metallurgy.

SUBSTANCE: furnace for secondary treatment of highly explosive materials containing noble metals and organic components, burnt with high energy release, contains at least one chamber and device for alternating switching of operation modes of furnace chamber between stages: A - by pyrolysis or semicoking in protective atmosphere, containing not more than 6 wt % of oxygen, and B - by oxidising burning of organic components, including carbon. Additionally furnace chamber allows indirect heating and control device, implemented wit ability of definition of stage of pyrolysis or semicoking by means of sensor and control of device for switching of operation mode of furnace chamber so that after finishing of pyrolysis or semicoking into furnace chamber it is fed air or oxygen. According to the invention, thermal afterburning can be used for two furnace chambers, one of which is in pyrolised mode or semicoking mode, and other operates in the capacity of combustion chamber.

EFFECT: ability of treatment for liquids with organic components, burnt with high energy release.
