ABSTRACT = {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 SO<sub>2</sub> 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.},
