| description | The utility model discloses a high-efficient recovery system of electric arc furnace steelmaking flue gas waste heat, it is including the activity flue, fixed flue, the deposit room, exhaust-heat boiler high temperature flue, exhaust-heat boiler, the heat accumulator, activity flue and fixed flue in-band heat preservation device, exhaust-heat boiler establishes vaporization water-cooling radiation heat transfer room, heat convection room etc, four hole flue gases of electric arc furnace are through the activity flue, fixed flue, the deposit room, then get into exhaust-heat boiler through exhaust-heat boiler high temperature flue behind the deposit room, the high temperature flue gas is in exhaust-heat boiler and membrane wall, radiation water-cooling screen, after evaporimeter and the economizer heat transfer, the temperature of flue gas is reduced by a wide margin, then discharge boiler system, discharge after removing dust, exhaust-heat boiler absorbs the heat and produces steam, after the steady voltage of entering heat accumulator, becomes continuous steam, supplies production or electricity generation to use. The utility model discloses can fully retrieve electric arc furnace flue gas heat, it is thermal more than 70% to reach the gas that the electric arc furnace is discharged fume. |
