A recycling facility includes a receptacle for receiving the ammunition to be cleaned, a gas tank for receiving a pressurized gas and coupled to the receptacle, for supplying the pressurized gas to the receptacle, and a heater coupled between the gas tank and the receptacle, for preheating the pressurized gas before the pressurized gas flowing into the receptacle, and for melting and removing the TNT material from the ammunition. The receptacle includes a control valve coupled between the heater and the receptacle, and a control valve coupled between the heater and the gas tank. A collecting casing may be coupled to the receptacle, and coupled to the gas tank via a filter.

The co-combustion process may comprise the following unit operations: routing of hot gas (10) generated in the clinker cooling process to a rotary kiln (1); use of part of the rotary kiln exhaust gas to dry solid wastes in rotary dryers; leading the gases from both the dryer and the combustion kiln to the secondary combustion chamber (2); use of additional fuel to boost up the secondary combustion chamber reaction temperature to as high as 1200.degree. C.; primary dry gas scrubbing in a precalciner or precalciners (3, 3a); heat recovery (4) and power generation; secondary gas scrubbing (5) in a semi-dry scrubber; bag filtering after activated carbon injection and returning of all the collected ash and used carbon into the waste kiln and/or a cement kiln. Detrimental materials for cement processing generated by waste combustion can be by-passed to a scrubbing system and a cement kiln. Residue slag from waste kilns can be treated and reused.

This relates to a furnace that is useful in safely detonating or demilitarizing munitions or explosives, particularly small caliber munitions. The preferred variation includes a series of chambers having a set of runners or tracks passing amongst the various chambers to allow movement of the munitions from chamber to chamber in trays. The first chamber is heated in such a way so that a tray of munitions placed on the runners in this chamber are baked and detonated. After the detonation is generally complete, the tray containing the then-detonated munition fragments is slid through an opening at the end of that heated detonation chamber into a first cooling chamber. Generally, this movement takes place by addition of another tray containing non-detonated munitions into the first chamber. The furnace may also contain a second cooling chamber to assure both that the subject munitions are detonated and to allow then-safe exiting of the completely detonated munitions from the second cooling chamber onto an external extension of the track. The furnace is configured so that the munitions, whether detonated or not, remain in trays which may be slid through an operating unit without substantial hazard. Also included is a scrubber for removing noxious or deleterious components of gases produced by the detonation before it is passed into the atmosphere. Finally, this includes a method of using a chambered furnace to detonate small arms munitions or other explosives.
