Definitions
- the invention relates to a method for producing liquid metal, in particular liquid pig iron or liquid steel intermediate products, from metal supports, in particular partially reduced or reduced sponge iron, in a melter, in the under Supply of at least partially formed from fine coal and coal dust carbon containing material and oxygen or oxygen containing gas in one from the carbon-containing material formed the metal support while forming a bed Reducing gas are melted down, if necessary after prior reduction, and an installation for carrying out the method.
- a problem in feeding fine particulate carbonaceous material such as Fine coal and coal dust in a smelting gasifier lies in the fact that fine particulate carbonaceous material due to the in the melter existing gas velocities are immediately withdrawn from this. This hits in the same measure also for fine particulate ore.
- the disadvantage is here that the carbon carrier does not help build a solid Carbon carriers formed bed in the melter can afford.
- Such a bed is usually made of chunky coal, which has high thermal stability must have formed. Due to the development of the coal market, which is affected by the If the requirements of the coal power plant operator are determined, it can happen that preference is given to fine coal for today's coal dust burners. The earlier usual grate firing, which made the use of lumpy coal necessary, only play a subordinate role in the coal consumer market. This has to Consequence that the fine portion of the coals offered on the market a considerable extent can assume, which is in the order of up to 50 to 70%.
- the first Fine part of the coal is sieved, so that only the coarse part, i.e. the lumpy coal, for use in the melter is available.
- the fine fraction becomes one otherwise used.
- the object of the invention is also to benefit the fine fraction in this way exploit that he to build a bed made of carbonaceous material in the Smelting gasifier contributes, making the cost of use lumpy carbon-containing material can be reduced.
- This object is achieved in that fine coal used and coal dust after drying in a warm state mixed with bitumen and are then cold briquetted and that the briquettes produced in the Smelting carburetor used in the cold state and in the smelting gasifier a shock heating be subjected.
- the briquettes produced in this way are excellent Have thermal stability, which even the thermal stability lumpy carbon-containing Materials surpasses.
- the briquettes show little disintegration in the shock-like acting temperatures of the melter gasifier of approx. 1000 ° C. This is due to the Properties of the bitumen used as a binder, which in the specified high temperature melts quickly and thereby to an advantageous Bridge formation between the carbon particles gives rise to. It is essential that the Bitumen does not outgass at the specified temperature and moreover its pasty Retains consistency and bindability.
- the briquettes are supposed to even in the event of sudden temperature shocks when charging into a melter do not burst, whereas according to DE-A - 24 07 780 it is important that the briquettes have a high level of stability, i.e. a high pressure resistance, in order in the blast furnace to be able to be used.
- a high level of stability i.e. a high pressure resistance
- fine coal and coal dust are at and / or after drying from the carbon-containing material used deposited and treated further when warm.
- Lumpy particles that accumulate when separating the fine coal and coal dust carbonaceous material is according to a preferred embodiment of the The inventive method used directly in the melter.
- Fine coal with a particle size of less than or equal to 8 mm is preferably obtained from the carbon-containing material deposited.
- a method is known from AT-B - 376 241, according to which the method from a Smelting gasifier with the reducing gas discharged from dust-like carbon existing solids are separated from the reducing gas and agglomerated and the agglomerates formed, in particular molded coke, are returned to the melter become.
- this is not what is used, as in the invention carbonaceous material agglomerates and there can be no fine coal to a greater extent are used.
- the procedure according to AT-B - 376 241 results The disadvantage then is that the agglomerating device immediately after the hot cyclone Separation of the dusty carbon is arranged, which is a considerable constructive effort.
- the carbon-containing material used is used separated fine coal or the coal dust mixed with bitumen and briquetted, whereby the briquetting follows the drying of the carbonaceous material.
- the fine coal and the Coal dust with the bitumen at a temperature below 100 ° C. preferably at one Temperature between 75 and 80 ° C, mixed.
- Bitumen with one is advantageous Softening point below 80 ° C, preferably below 75 ° C, used.
- carbon-containing material up to 30% petroleum coke used which in and of itself insufficient thermal stability.
- briquettes obtained nevertheless have a sufficiently high thermal stability.
- the carbon-containing material used is preferably applied to one Residual moisture content dried below 5%.
- briquette fragments are made from the fine coal and the briquettes formed from the coal dust are separated and recycled into the briquetting process.
- the briquettes formed from the fine coal and coal dust are advantageous in and / or cooled to a temperature below 30 ° C after briquetting. You assign one particularly high temperature stability, in particular due to the shock heating during Insert in the melter.
- coal with an ash content of 10 to 25% is expediently used.
- the method according to the invention is characterized by a particular high economy, so that the liquid metal, which is in the melter partially or fully reduced metal ores was smelted, inexpensively manufactured can, because for the melter gasifier, as described in the introduction, exactly that carbon-containing material used for the production of the briquettes, so to speak as a by-product in the recycling of the finely divided portion of the carbonaceous Material is used.
- coal with volatile fractions between 18 and 35% is also used. So it is not necessary to use high quality coal.
- the fine coal and the coal dust with the temperature from the Coal drying mixed with bitumen which has about the same temperature, expediently the temperature of the material to be mixed when mixing 70 to maximum 100 ° C, preferably 75 to 85 ° C.
- the Mixed product of fine coal, coal dust and bitumen not cooled or cooled only slightly before it is briquetted.
- bitumen bitumen to be used in the usual way for road construction. So it is not necessary to make special demands on the bitumen.
- a plant for performing the method according to the invention with a Smelting gasifier, with a feed line for the melting gasifier Metal carrier, especially for partially reduced or reduced sponge iron Supply lines for oxygen or an oxygen-containing gas and for at least partially Fine carbon and coal dust formed carbonaceous material, with a from Smelting carburetor outgoing derivative for formed in the smelting gasifier Reducing gas and a tapping for pig iron and Slag, is characterized in that a drying device for drying carbon-containing material is used, which is a mixer followed by a cold briquetting device for briquetting fine coal and Coal dust are connected downstream, the cold briquetting device in line with the Smelting gasifier is connected.
- a separating device for separating of fine coal and coal dust from the carbon-containing used Material provided.
- a feed line for the insertion of lumpy carbonaceous material is provided directly in the melter.
- a steam generator is expediently provided for heating the mixer.
- 1 denotes a melter gasifier, into which a feeder 2 at least partially reduced sponge iron 3 is introduced, which in Melting gasifier 1, if necessary after reduction, is melted down when passing through a bed made of carbon-containing material 4.
- the Smelting gasifier 1 is also provided with a feed line 5 for oxygen or oxygen-containing gas, with feed lines 6a, 6b for carbon-containing material, with a Derivation 7 for reducing gas formed in the melter gasifier 1 and with their own Tapping 8, 8a for molten pig iron 9 or molten slag 10 fitted.
- the carbon-containing material 11 used is in a first Drying device 12 dried.
- the resulting coal dust 13 is drawn off and further treated in a second drying device 14. That warm from the first Drying device 12 discharged carbonaceous material having a temperature of about 60 ° C, a separating device 15, for example a sieve, supplied, fine coal 16 separated from lumpy carbonaceous material 17 becomes. For example, fine coal 16 with a particle size smaller than or equal to 8 mm deposited.
- the lumpy carbonaceous material 17 is fed directly to the line 6b Melter gasifier 1 supplied.
- the fine coal 16 on the other hand, reaches a storage container 18 and from this to a mixer 19 in which the fine coal 16 is mixed with bitumen 20 that is taken from a bitumen tank 21. Furthermore, the mixer 19 Coal dust 13 from the second drying device 14, which is in a coal dust container 22 is stored temporarily.
- the mixer 19 is heated to approximately 75-80 ° C. by means of steam generated in the steam generator 23 warmed up. This ensures that the softening point of the supplied bitumen 20 is exceeded. But it is also possible that the heat content of the fine coal 16 is sufficient to bring in the heat energy necessary for the softening of the bitumen 20, so that no additional energy in the form of steam has to be used for this.
- the mixture of fine coal 16, coal dust 13 and bitumen 20 is then by means of a cold briquetting device 24 cold briquetted at a temperature of about 70 to 75 ° C, i.e. no additional thermal energy is used for the briquetting.
- the so Briquettes 25 produced are finally a device 26 for separating Briquette fragments that are not required for use in the melter 1 Have size supplied, which device 26 also serves as a cooling device.
- the briquettes 25 are cooled to a temperature below 30 ° C.
- the briquette fragments that are not those for use in the melter 1 have the required size, are recycled into the briquetting process. You get first in a collecting container 27 and from this into the storage container 18 for fine coal 16.
- the briquettes 25 are fed via the feed line 6a to the melter gasifier 1, in which they undergo shock heating. Surprisingly, it has been shown that the Briquettes 25 have an extremely high thermal stability, which is even higher than that Thermostability of the lumpy carbonaceous material 17, as by the following example is clarified.
- South African and Australian hard coal were produced using the process according to the invention dried and screened, with a fraction of lumpy coal and coal dust and Fine coal was obtained.
- the coal dust and fine coal were using the Briquetting method according to the invention briquetted.
- the thermal stability of the so produced Briquettes were then compared to the thermal stability of the particular lump of 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 proportions with a particle size above 10 mm or with a particle size below 2 mm were in each case weighed out and given as a percentage of the amount used.
- the results are summarized in Table 1.
- South African hard coal Australian coal Charcoal Briquettes Charcoal Briquettes Thermostability + 10 mm% 77.6 86.4 77.7 82.4 - 2 mm% 3.1 2.6 3.4 2.4
- the procedure according to the invention thus makes briquettes of fine coal and Coal dust provided, which have an extremely high thermal stability, so that they can be easily used in a melter, the Disintegration of the briquettes even at the shocking temperatures of Melting gasifier of approx. 1000 ° C is very low.
- This enables the use of Fine coal and coal dust in a melter gasifier in an economical manner, namely in the kind that the briquettes produced from the fine coal and the coal dust to build up a contributed from carbon carriers in the melter gasifier, thereby saved considerable costs for the use of lumpy carbonaceous material can be.
