MANUFACTURING METHOD OF SOLID FUEL MADE FROM INDUSTRIAL AND DOMESTIC WASTES Russian patent published in 2010 - IPC C10L5/48 C10L5/46 

FIELD: power industry.

SUBSTANCE: manufacturing method of solid fuel made from industrial and domestic waste consists in the fact that industrial and domestic wastes are divided into three groups at the first step. The first group includes large-sized metal objects, cords and hazardous substances which are removed from total weight of basic objects for manufacturing of solid fuel and then they are disposed. The second group includes large-sized industrial and domestic wastes. The third group contains the wastes which are less than 150 mm as per overall dimensions. At the second step the wastes of the second group are placed in screw crusher for decreasing their overall dimensions to less than 150 mm. At the third step the wastes of the second and the third group are supplied to horizontal crushing plant to decrease their volume. At the fourth step, lime is added to wastes obtained in horizontal crushing plant. Moulding of round briquettes is performed at high pressure and temperature and their drying so that final product is obtained with diametre of 15-30 mm, 30-150 mm long, calorific value of more than 6000 kcal/kg and combustion temperature of more than 1100 deg/C.

EFFECT: simplifying manufacturing procedure of solid fuel from industrial and domestic wastes.
