Definitions

• the present invention relates to the production of fuel briquettes and particularly the production b means of coal dust of briquettes or ba perforated or not, and other briquetted fuel products of the same description.
• the precise object of the present invention is to enable petroleum tars to be used under the conditions and with the standard plant for the production of briquettes with coal tar, and .more particularly the use,
• the subject of the invention is aprocess for the production of fuel briquettes or agglomerates, more particularly of coal dust, in which the binding material employed is composed of asphaltic bitumens with a melting point varying by preference, between 90 C. and 120 (J.
• the briquetted or agglomerated fuels obtained in all shapes offer the advantage as compared with those existing at present, of igniting rapidly onintroduction into the furnace and of producing a flame of a very high temperature, burning all the products of distillation of the agglomerant and consequently avoids ing any production of smoke.
• the steps which comprise reducing to fluid condition a petroleum tar having a melting point between 90 C. and 120 C.. causing said tar to foam, solidifying said foaming tar by sudden cooling of the same, reducing said solidified tar to Bennettely divided condition, and utilizing such finely divided tar as a binder for finely divided solid fuel.
• the ste s which comprise reducing to a fluid condition a petroleum tar having a melting oint between 90 .C. and 120 (1., treating t e fluid tar with bicarbonate of soda to cause the tar to foam by the gas liberated from said soda, solidifying the tar by sudden cooling, reducing the solid ified tar to a finely divided condition, and utilizing such finely divided tar as a binder for finely divided solid fuel.
• the steps which comprise reducing to a fluid condltion a petroleum tar hava melting point between 90 C. and 120 (l, treating the fluid tar with bicarbonate of soda to cause the tar to foam by the gas liberated from said soda, running said foaming tar into cold water to solidi the same, reducing the solidified tar to a ely divided condition, and utilizing such finely divided tar as a binder for finely divided solid fuel.
