KNOW YOUR BLAST FURNACE BOSH DESIGN

[00:00:00]In blast furnace engineering, the bosch angle is your anchor for the burden stability. Measured from the vertical axis, this inclination determine whether your material flow smoothly or stick to the furnace wall.

[00:00:14]So, a small bosch angle create a steep wall which drastically increase wall friction and risk of a scaffolding, especially when using poor quality of burden.

[00:00:25]This leads to poor gas permeability and dangerous operational hangs. To compensate for the lower burden quality, modern design utilizes a larger, more open bosch angle that is up to 82° to reduce friction and improve liquid drainage. Optimize your bosch geometry to stabilize the material descent and prevent the catastrophic stream that leads to explosion.
