Definitions

  • the present invention relates to a process for the preparation of stable mixtures of coal and oil, using water as the stabilizer additive.
  • coal is presently hindered to a determining_extent by the need of substantial investments having to be done to the purpose of modify the fuel combustion, storage and handling systems.
  • One of such technologies is that of producing mixtures of coal and fuel oil.
  • the first type consits in accomplishing a ultra-fine grinding of the coal, so as to produce a colloidal suspen sion.
  • Such a type of process requires high investment and operating costs for the ultra-grinding, and requires as well the use of equipment which is not yet completely reliable from the constructive viewpoint.
  • a known process using water as the stabilizer additive consists in grinding coal down-to particle size comprised within the range of from 3 to 6 mm, mixing it with water, mixing the water-coal mixture with oil and finally grinding the mixture formed down to 0.5 mm.
  • the process which is the object of the present invention comprises the following steps:
  • the homogenizing can be obtained by means of the impact of the mixture containing water, coal and oil against a surface preferably perpendicular to the flow direction of the mixture itself.
  • the water content in the mixture as under point (c) is preferably comprised within the range of from 8 to 12% by weight relatively to the mixture itself.
  • the usable oil can be fuel oil.
  • the coal ground has been mixed first with water in an amount of about 22.2% by weight relatively to the coal and then with heavy fuel oil; the mixture formed has been homogenized by means of the emulsifier equipment schematically shown in herewith enclosed figura, a brief explanation of which is now given.
  • the mixture of coal, oil and water (1) enters, delivered under pressure, the equipment, runs through the feed ing duct (2), then through the convergent cone-frustum shaped duct (3), subsequently at high speed through the duct of constant section (4), and penetrates then into a chamber (5), called plenum chamber, of cylindrical shape with movable adjustable bottom (6), going to collide with the same bottom of said chamber.
  • the mixture passes from the ple num chamber through a plurality of holes (7) uniformly dis tributed in the lateral wall (8) of said chamber into a discharge chamber (9) annular and coaxial to the said plenum chamber and leaves (10) the device.
  • the discharge chamber is bounded by the outer wall of the plenum chamber and by a cylindrical manifold (11).
  • the feeding duct, the cone-frustum shaped duct and the duct of constant section are made in two blocks (12) and (13).
  • the movable adjustable bottom allows the length and obviously the volume of the plenum chamber to be varied above all on the basis of the flow rate and of the composition of the mixture.
  • the dimensions of the emulsifier used are the following: angle between the major base and the lateral wall of the cone-frustum shaped duct 60°
  • the diameter of the plenum chamber and the diameter - of the constant-section duct have been so selected, as to obtain a 5 bar drop in mixture pressure between the inlet of the constant-section duct and the plenum chamber.
