MOULDED FUEL AND PREPARATION METHOD THEREOF Russian patent published in 2010 - IPC C10L5/42 C10L5/44 

FIELD: chemistry.

SUBSTANCE: moulded fuel contains a dry mixture of wood wastes and wastes from starch production in ratio of 3:1 and lipid-containing animal wastes in the following ratio of components, wt %: said lipid-containing wastes 30-60; mixture of ground solid fuel and starch production wastes - the rest. The lipid-containing wastes are wastes from fish processing, meat processing and bird processing. The method of producing moulded fuel involves selection of components, grinding and mixing the ground solid fuel, moulding the mixture, wherein before grinding, the solid components are separated on vibrating screens into two fractions with particle size less than 8 mm and greater than 8 mm and the latter is taken for grinding. Each fraction is then taken for drying and the components are dried to moisture of 12-16%. The components are then mixed and the mixture is then moulded in an extruder at pressure of 5-10 MPa and temperature of 140-200°C. The ready fuel is packed into sacks.

EFFECT: invention enables recycling and utilisation of wastes from food production and improves physical and mechanical properties of the fuel blocks.
