New Technologies for Prolonging Coke Oven
Life Shizuki Kasaoka, Takeshi Andou |
Synopsis: New technologies were developed to protect coking chamber bricks from damage caused by hard-deposited carbon. A glass coating on the wall bricks and a wall cleaner installed on a pusher ram are used to prevent carbon from being deposited to the wall bricks. Coating can be carried out in a few minutes via a throughwall chamber with a special glaze that is applied by a newly developed spraying device. The glazed layer is automatically cleaned by a high-velocity air blast during coke pushing. The life of the glassy layer is estimated to be over two years. A supplementary burner system at end flues and a pressure control system at gooseneckes were also developed to prevent pushng emissions and stack emissions respecitively. |
