Resistance issues in the acid production system using smelting flue gas
Thread Content
Acid production system using smelting flue gas; the system comprises a roasting furnace, a waste heat boiler, a cyclone dust collector, an electrostatic dust collector, an internal injection Venturi tube, a packed tower, two-stage electrostatic fogging, and a 3+2 two-turn two-suction design. With a production capacity of 70 kt/a and the output increased to 80 kt/a, while the SO2 concentration remains unchanged, the gas flow rate increases by 15% – by how much can the system resistance increase?
My estimate is that the system resistance increases by more than 20%; it’s higher in cases like venturi tubes, while it’s lower for devices such as electrostatic mist eliminators.
The resistance will certainly increase; you can refer to available data for calculations – it’s not possible to estimate it based on experience alone; we need some theoretical basis.
