Definitions

  • the present invention is concerned with fuel briquettes and, in particular, briquettes made from carbonaceous fuel particles, such as powdered fine coal.
  • Coal briquettes are conventionally formed by bonding together coal particles using an organic binder; many such binders have been proposed, including molasses, which is known for use in a low temperature briquetting process.
  • molasses which is known for use in a low temperature briquetting process.
  • Various inorganic hardening agents have been proposed for the molasses binder, such as lime (GB 2161449), phosphoric acid (GB 230306), and calcium phosphate, ferric oxide, calcium carbonate and/or aluminium oxide (GB 2187754).
  • a fuel briquette comprising carbonaceous fuel particles bonded together by means of a binder comprising molasses in an amount of at least 5% by weight, based on the weight of the briquette, and a minor amount of an inorganic hardening agent for the molasses, the hardening agent comprising an alkali metal phosphate and/or an alkaline earth metal sulphate.
  • the alkali metal phosphate is preferably pentasodium triphosphate (sodium orthophosphate) and the alkaline earth metal sulphate is preferably magnesium sulphate.
  • the inorganic hardening agent is preferably present in an amount of 0.02 to 5% by weight, based on the weight of the briquette.
  • the molasses is preferably present in an amount of 2 to 20% by weight (such as about 5 to 15%) based on the weight of the briquette.
  • Phosphoric acid and/or sulphuric acid may additionally be incorporated, generally in amounts not exceeding 2% by weight of the briquette.
  • the binder should be substantially free of synthetic polymer binders; the molasses used as the binder may be cane or beet molasses.
  • the carbonaceous fuel used in the briquettes according to the present invention may be charcoal, coke, or coal.
  • the preferred fuel is a high rank non-caking coal, typically of the low smoke type, such as anthracite.
  • the fuel generally has a particle size below 3mm; anthracite duff is particularly preferred.
  • Other coals which may be used are steam coals, and heat-treated coals.
  • the briquettes according to the invention may be formed as agglomerates by extrusion, ringroll or roll pressing, die pressing, rotary table pressing, pelletising or the like.
  • the green briquettes may be allowed to harden, for example, at room temperature over one to three days, or cured at elevated temperature (e.g. at 200 to 300°C for up to one hour). This hot curing may be carried out in an oven containing an inert or partially inert atmosphere.
  • Anthracite dust was dried, crushed and screened to approximately 3 mm, and then mixed with 8% molasses, 1% phosphoric acid and 0.3% magnesium sulphate. The mixture was then formed into briquettes and cured at 260°C for one hour in an oxygen-controlled atmosphere. The resulting briquettes were substantially non-friable and had satisfactory water-resistance.
  • Example 1 was repeated, except that the magnesium sulphate was replaced by the same quantity of sodium orthophosphate. Similar results were obtained.
  • Example 1 was repeated, except that 0.2% of the magnesium sulphate was replaced by the same quantity of sodium orthophosphate. Similar results were obtained.
