METHOD AND REACTOR FOR THERMAL DECONTAMINATION OF WASTE GASES OF COMMERCIAL CARBON PRODUCTION PROCESS Russian patent published in 2003 - IPC

FIELD: technology of decontamination of low-caloric waste gases of commercial carbon production process. SUBSTANCE: proposed method includes mixing of air with fuel, ignition of this mixture and burning of it forming flow of high-temperature oxidizer followed by expansion of flow and tangential introduction of waste gases in this flow. Smoothly widening flow of high-temperature oxidizer is formed in zone of mixing fuel with air; velocity of this flow at initial section ranges from 50 to 200 m/s; velocity of tangential flow of waste gases ranges from 15 to 80 m/s. Reactor proposed for realization of this method includes fuel combustion chamber with axial burner, combustion chamber for gases to be decontaminated, mixing chamber and after-burner chamber mounted axially and in succession. EFFECT: enhanced efficiency of burning-out of toxic components. 3 cl, 2 dwg, 1 tbl
