the residue from distillation of gasoline, ligroin, kerosine, and diesel oil fractions from petroleum. Mazut may be used as boiler fuel oil, in the preparation of distillate and residual lubricating oils, in cracking or hydrogenation processes for the manufacture of motor fuel (gasoline or diesel oil), and in the production of bitumen and coke, depending on its chemical composition and properties.

The properties of mazut are as follows: density, 890-1,000 kg/m3 at 20°C; heat of combustion, 38-42 megajoules per kg (9,100-10,000 kcal/kg); relative viscosity, 5°-15° at 50°C; surface tension, 0.03-0.04 joules per sq m (30-40 erg/cm2) at 40°C); heat of evaporation, 170-210 kilojoules per kg (40-50 kcal/kg); sulfur content, 0.8-3.5 percent; resin content, up to 60 percent; ash content, 0.1-0.5 percent. The mazut used for fuel in gas turbines must have the lowest ash content (the ash must contain no more than 0.001 percent vanadium and 0.0005 percent sodium, which are particularly harmful elements in terms of corrosion).
