Definitions
- the object is achieved in that granular coal and preheated granular iron ore are placed in a smoldering reactor in which temperatures in the range from 800 to 1050 ° C. are generated by supplying oxygen-containing gas and by partial oxidation of the constituents of the coal, the granules being produced Keeps solids in a swirling motion and leads from the upper area of the reactor to a solids separator, from which one discharges a hot exhaust gas, that one preheats the granular iron ore with the hot exhaust gas, and that a hot, granular mixture of iron ore and smoked coke is produced withdrawing from the reactor and / or from the separator.
- the smoldering reactor can be designed, for example, as a fluidized bed reactor or as a pneumatic conveying path.
- the pressure in the carbonization reactor is usually in the range from 1 to 10 bar and preferably from 2 to 7 bar.
- highly volatile coal including lignite
- the coal can also contain water.
- the coal that is fed to the smoldering reactor has grain sizes of up to about 10 mm and preferably up to a maximum of about 6 mm, the grain sizes of the iron ore are in the range up to 10 mm and preferably up to 6 mm.
- the Fe: C weight ratio is usually in the range from 1: 1 to 2: 1.
- a smoldering reactor (1) is fed through the line (2) of granular coal and through the line (3) preheated granular iron ore. Air for the partial oxidation in the reactor (1) and for the swirling and the transport of the solids is introduced in the line (5) and enters the reactor (1) through a distributor (6). Secondary air is introduced in line (4). Temperatures in the range of 800 to 1050 ° C and mostly 850 to 1000 ° C are ensured in the reactor. The residence times for the solids in the reactor (1) are approximately in the range from 2 to 20 seconds.
- the solids are conducted from the upper area of the reactor (1) through the channel (8) to a separator (9) designed as a cyclone.
- the largely solid-free hot exhaust gases flow upwards into a suspension heat exchanger (10), to which iron ore from the outside is fed through the line (1 l).
- This iron ore is preheated in direct contact with the hot exhaust gas and passed through line (12) to a separating cyclone (13), from where the preheated iron ore passes through line (3) back into the reactor (1).
- Exhaust gas is drawn off in line (14) and is fed to a gas cleaning device, not shown.
