Gases containing sulfur oxides can cause corrosion and failure of bellows used as furnace blowers in high-temperature environments. In order to mitigate this issue, the behavior of an effective blast furnace blower has been examined in detail. Firstly, the Sereda corrosion model has been introduced to simulate the corrosion rate of the related bellows taking into account the effects of temperature and SO2 gas; such results have been compared with effective measurements; then, the average gas velocity in the pipeline and the von Mises stress distribution of the inner draft tube have been analyzed using a Fluid-Structure Interaction model. Finally, the semi-closed internal corrosion environment caused by a 5 mm radial gap between the inner draft tube and the bellows has been considered. The gas flow rate in the residential space has been found to be low (0.5 ms–this value leads to a stable semi-closed internal corrosion environment for exhaust gas exchange); water phase in the exhaust gas is prone to accelerate the corrosion rate. On this basis, a bellows with an optimized inner draft tube has proposed, which includes corrosion-resistant honeycomb buffer rings.
