Abstract RU 2131449 C1

FIELD: solid fuels. SUBSTANCE: invention relates to technology of production of molded (briquetted, extruded, or granulated) solid fuel that can be used both in household and in industrial areas. Molded fuel is fabricated from dried mixture of ground solid fuel and 13 to 38 wt % of concentrated (5-24% moisture) sludge from waste water treatment plants originally containing 70-80 wt % water. Mixture is molded at pressure 0.1 to 25 MPa and molded products are dried for 1.5-0.4 h at 50-180 C or for 5 to 30 h at ambient temperature. EFFECT: increased mechanical strength. 4 cl, 11 ex
