Description

  

  Procédé de fabrication de briquettes combustibles.    La présente invention a pour objet un  procédé     @de    fabrication de briquettes combus  tibles composées d'un mélange de tourbe,  d'un charbon minéral: anthracite     ou-houille,     et d'un brai: goudron, bitume, etc.  



  Suivant ce procédé de fabrication, on  broie de la tourbe, séchée jusqu'à ce que sa  teneur en eau soit comprise entre 8 et 10 %,  en grains dont les dimensions ne dépassent  pas 4 mm, et la mélange avec un charbon mi  néral broyé au préalable en grains de dimen  sions ne dépassant pas 4 mm; on chauffe ce  mélange ensuite à une température de 80 à  120   C et on lui ajoute, alors qu'il est chaud,  un brai chaud additionné de particules solides       combustibles,    et,     finalement,    on forme, par  compression, les briquettes combustibles.  



  Les     proportions    exprimées en % des  constituants utilisés     pour    la fabrication des  briquettes     combustibles    peuvent varier et  sont     comprises    de préférence entre les va  leurs suivantes: Tourbe: 88-60%,     charbon     minéral: 7-15 %, brai avec lesdites     parti-          cul-es:    10-25 %.    Voici un exemple de fabrication des bri  quettes combustibles selon le procédé décrit:  La tourbe est séchée ,jusqu'à ce que sa  teneur en eau diminue jusqu'à 8 à. 10%, puis  elle est broyée en grains de 4 mm au maxi  mum.

   On la mélange ensuite avec de l'an  thracite broyé aussi en grains de mêmes di  mensions et l'on chauffe ce mélange à une  température de 80 à 120   C. On ajoute en  suite à ce mélange de tourbe et d'anthracite  un brai chaud, auquel on a ajouté un peu ide  poudre de charbon de tourbe et on     continue     à     brasser    ce mélange     pendant    que les consti  tuants sont chauds. Enfin, en comprimant la  pâte obtenue, on forme les     briquettes        com-          bustibles.     



  On peut aussi     utiliser,    en addition     dans     le brai chaud, de la     poudre    -de charbon de  bois, -du     poussier    de charbon ou encore de  la sciure de bois.



  Manufacturing process of combustible briquettes. The present invention relates to a process @de manufacture of combustible briquettes composed of a mixture of peat, a mineral coal: anthracite or coal, and a pitch: tar, bitumen, etc.



  According to this manufacturing process, peat is ground, dried until its water content is between 8 and 10%, into grains whose dimensions do not exceed 4 mm, and mixed with a ground mineral coal. in advance in grains of dimensions not exceeding 4 mm; this mixture is then heated to a temperature of 80 to 120 ° C. and to it is added, while it is hot, a hot pitch with the addition of solid combustible particles, and, finally, the combustible briquettes are formed by compression.



  The proportions expressed as% of the constituents used for the manufacture of the fuel briquettes can vary and are preferably between the following values: Peat: 88-60%, mineral coal: 7-15%, pitch with said particles : 10-25%. Here is an example of the production of fuel briquettes according to the described process: The peat is dried, until its water content decreases to 8%. 10%, then it is ground into grains of 4 mm maximum.

   It is then mixed with an thracite also ground into grains of the same dimensions and this mixture is heated to a temperature of 80 to 120 C. A hot pitch is then added to this mixture of peat and anthracite. , to which a little peat charcoal powder has been added and this mixture is continued to be stirred while the constituents are hot. Finally, by compressing the paste obtained, the combustible briquettes are formed.



  It is also possible to use, in addition to the hot pitch, charcoal powder, charcoal dust or even sawdust.
