TECHNOLOGY FOCUS - INSTRUMENTATION AND TESTING - Preferred Components: The material stream is pressed under exclusion of oxygen with an extrusion press by a rotating mouth against a fixed thermal plate. The thermal plate is heated by a pumpable heating medium at 400-400 degrees C. The contact pressure of the material stream on the thermal plate is 5-100 kg/cm2. The heating medium consists of fusible salt mixtures or metal alloys with melting point greater than 200 degrees C and the boiling temperature greater than 1750 degrees C. The contact pressure and the temperature of the thermal plate are related to the composition of the material stream and by this parameter, the desired amount and form of energy products and slag attack are adjusted. The circulation of the heating medium takes place by a rotating screw between, which the first train channel and dry hot gases enclosed and warms up. The combustion gases for the burner consists of the own testified noncondensable proportions of the hot gas. The dry exhaust gases from the heat generator are involved for drying the material stream in the dryer. The material bed in the dryer through the screw shaft in material flow direction and simultaneously moved by changing the direction of rotation (A and B) based on the direction of the exhaust gas flow, which is guided in cocurrent or countercurrent. The blades of the material bed are changing by the direction of rotation (A and B) and sales the material continuously creating new surfaces with, which the hot exhaust gas flow is dried. The thermal plate in a vertical arrangement on both sides has surface grooves, by which the hot gases are removed upwards and held downward the solids. The density of the compressed material stream in the mouth is greater than 1.2 kg/dm3. The gap adjustment between the mouths is carried out by the adjustment device. The compacted fill material is rotated with the rotational movement of the tube through the mouth partition wall or grooves in the mouth tube.
