Conclusions Cyclones installed as the first stages of purification and operating with relative gas velocities of 6 m/sec, upon entry of the dust-laden gas containing 40–55 g/nm3, have an efficiency of 0.82, which is higher than the planned level (equal to 0.70). The electric filters installed as the secondary stage of purification with gas dust contents at the entrance of 5.3–8.6 g/nm3, a temperature of 170–190°C and an operational velocity in the equipments active zone of 1.15 m/sec, operate with an efficiency of 0.847. The low efficiency of electric filters is due to the high resistivity of the dust, equal to 2.7×1013 Ω·cm at 30°C, and the inadequate power of the semiautomatic supply units AFAP-80-225 (M) with mechanical rectifiers. One of the ways of intensifying the operation of electric filters used to extract high-ohmic dust is to reduce the gas velocity in the active zone of the equipment. To increase the efficiency of the electric filter it is necessary to install automatic supply units for the electric filters of the type ARS-400 with semiconducting rectifiers.
