RESIDUAL FUEL OIL ASH PROCESSING METHOD Russian patent published in 1995 - IPC

Abstract SU 1340188 A1

FIELD: residual fuel oil heat power stations ash processing. SUBSTANCE: during comminution of initial product iron-bearing reagent is added up to mass ratio of iron and nickel of 3.7 40 1 and than two staged burning with insertion of calcium-bearing addition is exercised. First stage is carried out with special consumption of air beginning from 6 m³/h per kg of charge. After burning hydrometallurgical treatment is exercised. Heat power electrical stations residual fuel oil slimes are used as iron-bearing reactant. EFFECT: increased share of nickel in concentrate and decrease of vanadium losses. 2 cl, 2 tbl
