Definitions
- the invention relates to a process for the production of liquid metal, in particular liquid pig iron or liquid steel precursors, from metal supports, in particular partially reduced or reduced sponge iron, in a melter gasifier in which carbon-containing material and oxygen or oxygen-containing material are formed, at least in part from carbon and coal dust Gas in a bed formed from the carbon-containing material, the metal supports are melted while simultaneously forming a reducing gas, if necessary after a pre-existing reduction, and a plant for carrying out the method
- a problem with the feeding of fine-particulate carbon-containing materials, such as carbon and coal dust, into a melter gasifier is that the particulate carbon-containing material is immediately discharged from it again due to the gas velocities present in the melter gasifier.
- Such a bed is usually formed from stucco coal, which must have a high thermal stability. Due to the development of the coal market, which is determined by the requirements of the coal-fired power plant operators, it may happen that fine coal is preferred for the coal dust burners common today Grate furnaces, which made the use of stuck coal necessary, only play a subordinate role in the coal consumer market As a result, the fine portion of the coal offered on the market can assume a considerable extent, which is of the order of up to 50 to 70%.
- the fine fraction of the coal usually has to be screened off first, so that only the coarse fraction, i.e. the lumpy coal that is available for use in the melter.
- the fine fraction is used for other purposes.
- the invention has for its object to utilize the fine fraction also useful in such a way that it contributes to the construction of a bed made of carbonaceous material in the melter gasifier, whereby the cost of using lumpy carbonaceous material can be reduced.
- the briquettes produced in this way have excellent thermal stability, which even exceeds the thermal stability of particulate carbon-containing material.
- the briquettes show little disintegration at the shocking temperatures of the melter gasifier of approx. 1000 ° C. This is due to the properties of the bitumen used as a binder, which melts rapidly at the specified high temperature and thus gives rise to advantageous bridging between the carbon particles. It is important here that the bitumen does not outgas at the specified temperature and also retains its pasty consistency and binding capacity.
- these briquettes fulfill a different requirement than the briquettes produced according to the invention, especially since the briquettes according to the invention are dependent on thermal stability, ie the briquettes should not burst even in the event of sudden temperature shocks when charging into a melter, whereas according to DE-A-24 07 780 it is important that the briquettes have a high level of stability, that is to say a high pressure resistance, so that they can be used in the blast furnace.
- the high vacuum bitumen is heated to 200 ° C. and, after mixing with the fine coal, briquetted at a temperature of approximately 85 ° C. Due to the high proportion of coke formers in the known briquettes, a coke structure is formed, which results in a high level of stability.
- fine coal and coal dust are separated during and / or after drying from the carbon-containing material used and are further treated in the warm state.
- lumpy carbon-containing material is used directly in the melter gasifier according to a preferred embodiment of the method according to the invention.
- Fine coal with a particle size of less than or equal to 8 mm is preferably deposited from the carbon-containing material.
- EP-B-0 315 825 discloses a process of the type described in the introduction in which fine coal is mixed and granulated after grinding with a binder, such as lime, molasses, pitch or tar, and then introduced into a melter gasifier. According to the invention, however, the briquettes are not granulated but briquetted, the briquettes being more thermomechanically stable than granules.
- Another disadvantage according to EP-B - 0 315 825 is the high amount of energy required to grind the fine coal. According to the invention, this disadvantage is avoided in that the carbon-containing material used is not ground, but the fine coal and the coal dust are separated off.
- AT-B - 376 241 a method is known, according to which the solids discharged from a smelting gasifier with the reducing gas and consisting of dusty carbon are separated from the reducing gas and agglomerated and the agglomerates formed, in particular molded coke, are returned to the smelting gasifier.
- the carbon-containing material used is not agglomerated and fine coal cannot be used to a greater extent.
- the procedure according to AT-B - 376 241 results Disadvantage in that the agglomeration device is arranged immediately after the hot cyclone for the separation of the dust-like carbon, which requires considerable construction effort 1 .
- the fine coal separated from the carbon-containing material used or the coal dust is mixed with bitumen and briquetted, with the briquetting following the drying of the carbon-containing material.
- the heat content of the fine coal and the coal dust after drying is expediently used in the mixing process with bitumen and in briquetting. No additional thermal energy has to be used for briquetting.
- the fine coal and the coal dust are mixed with the bitumen at a temperature below 100 ° C., preferably at a temperature between 75 and 80 ° C.
- the carbon-containing material which in and of itself has inadequate thermal stability.
- the briquettes obtained by means of the procedure according to the invention nevertheless have a sufficiently high thermal stability.
- the carbon-containing material used is preferably dried to a residual moisture content of less than 5%.
- briquette fragments are separated from the briquettes formed from the fine coal and the coal dust and recycled into the briquetting process.
- the briquettes formed from the fine coal and the coal dust are advantageously cooled to a temperature below 30 ° C. during and / or after the briquetting. They have a particularly high temperature stability, in particular due to the shock heating when inserted into the melter.
- coal with an ash content of 10 to 25% is expediently used.
- the method according to the invention is characterized by a special high cost-effectiveness, so that the liquid metal, which was melted in the melter from partially or fully reduced metal ores, can be produced inexpensively, because, as described in the introduction, exactly the carbon-containing material is used for the melter, which is used for the production of the b ⁇ ts , which are, as it were, a by-product of the recycling of the fine portion of the carbonaceous material, is used
- coal with volatile fractions between 18 and 35% is also used. It is therefore not necessary to use high-quality coal
- the fine coal and the coal dust are preferably mixed with the temperature from the coal drying with bitumen which has approximately the same temperature, the temperature of the material to be mixed expediently being 70 to a maximum of 100 ° C., preferably 75 to 85 ° C., during the mixing This ensures a good binding effect of the bitumen, as well as cost-effective temperature control.
- the mixed product of carbon, coal dust and bitumen does not have to be cooled, or only cooled, before it is chained
- bitumen which is customarily used for road construction can be used as bitumen. It is therefore not necessary to make any special demands on the bitumen
- a system for carrying out the method according to the invention with a melter gasifier, with a feed line for metal supports, in particular for partially reduced or reduced sponge iron, with feed lines for oxygen or em oxygen-containing gas and for carbon-containing material formed at least partially from carbon and coal dust
- a discharge from the melter gasifier for reducing gas formed in the melter gasifier and a racking for pig iron and slag provided on the melter gasifier is characterized in that a drying device is provided for drying carbon-containing material which is used, which mixer and then a cold chaining process from B ⁇ Fine coal and coal dust are connected downstream, the Kaltb ⁇ kettierein ⁇ chtung is wired connected to the melter gasifier
- a separating device is provided for separating fine coal and coal dust from the carbon-containing material used.
- a feed line for inserting lumpy carbon-containing material is provided directly in the melter gasifier.
- a steam generator is expediently provided for heating the mixer.
- a device for separating briquette fragments is preferably provided between the cold briquetting device and the melter gasifier.
- 1 denotes a melter gasifier, into which at least partially reduced sponge iron 3 is introduced via a feed 2, which is melted down in the melter gasifier 1, if necessary after reduction, when it passes through a bed 4 made of carbon-containing material
- Smelting gasifier 1 is also provided with a supply line 5 for oxygen or an oxygen-containing gas, with supply lines 6a, 6b for carbon-containing material, with a discharge line 7 for reducing gas formed in the melting gasifier 1 and with its own taps 8, 8a for molten pig iron 9 or molten metal Slag 10 equipped.
- the carbon-containing material 11 used is dried in a first drying device 12.
- the resulting coal dust 13 is drawn off and further treated in a second drying device 14.
- the carbon-containing material which is discharged warmly from the first drying device 12 and has a temperature of approximately 60 ° C. is fed to a separating device 15, for example a sieve, fine carbon 16 being separated from lumpy carbon-containing material 17.
- fine coal 16 with a particle size of less than or equal to 8 mm is deposited.
- the lumpy carbonaceous material 17 is fed directly to the melter 1 via the feed line 6b.
- the fine coal 16 on the other hand, reaches a storage container 18 and from there to a mixer 19 in which the fine coal 16 mixes with bitumen 20 which is removed from a bitumen tank 21.
- the coal dust 13 from the second drying device 14, which is temporarily stored in a coal dust container 22, is also fed to the mixer 19
- the mixer 19 is heated to approximately 75-80 ° C. by means of steam generated in the steam generator 23. This ensures that the softening point of the bitumen 20 supplied is exceeded. However, it is also possible that the heat content of the carbon 16 is sufficient to achieve the softening of the bitumen 20 necessary heat energy, so that no additional energy in the form of steam has to be used for this
- bitumen 20 used can be ordinary petroleum bitumen for road construction purposes with a softening point below 75 ° C., which is available worldwide inexpensively, for example bitumen of the type B70 according to ONORM B3610, which has the following specifications
- Ring and ball softening point (ONORM C 9212) 47 - 54 ° C needle penetration at 25 ° C (ONORM C 9214) 50 - 80 mm x 10 '
- the mixture of carbon 16, coal dust 13 and bitumen 20 is then cold briquetted by means of a cold chain 24 at a temperature of about 70 to 7 ° C., ie no additional thermal energy is used for chaining.
- the chains 25 thus produced are finally a device 26 for separating fragments of briquettes that do not have the size required for use in the melter gasifier 1, which device 26 also serves as a cow liner.
- the briquettes 25 are cooled to a temperature of below 30 ° C.
- the chain fragments which do not have the size required for use in the melter gasifier 1 are recycled in the chaining process. They first arrive at a collecting container 27 and from there into the storage container 18 for carbon 16
- the chains 25 are fed via the feed line 6a to the melter gasifier 1, in which they are subjected to shock heating. Surprisingly, it has been shown that the chains 25 have an extremely high thermostability, which is even higher than the thermostability of the stucco carbon-containing material 17.
- the following example shows South African and Australian hard coal were dried and screened using the process according to the invention, a fraction of lumpy coal and of coal dust and fine coal being obtained.
- the coal dust and fine coal were briquetted using the briquetting method according to the invention. The thermal stability of the briquettes thus produced was then compared with the thermal stability of the respective lumpy coal.
- the thermal stability was determined in such a way that a feed fraction with a particle size of 10 to 16 mm was subjected to a thermal treatment and was sieved off after the thermal treatment.
- the proportion with a particle size above 10 mm or with a particle size below 2 mm was in each case weighed out and stated in percent of the amount used. The results are summarized in Table 1.
- the procedure according to the invention thus provides briquettes made of fine coal and coal dust, which have an extremely high thermal stability, so that they can be used without further ado in a melter gas, with the briquettes also decaying at the shock-like temperatures of the melter gasifier of approx. 1000 ° C is very low.
- the use of fine coal and coal dust in a melter gasifier succeeds economically, in such a way that the briquettes produced from the fine coal and coal dust contribute to the formation of a bed formed from carbon carriers in the melter gasifier, which results in considerable costs for the use of lumpy carbonaceous materials Materials can be saved.
