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%.

  • 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.
