Before pushing out the coke, the furnace lid is opened in advance – how much time in advance usually? What are the negative effects of opening the furnace door or lid too early?
We request that the dust removal hole covers and the rise pipe covers be opened 15 minutes in advance; otherwise, the graphite may burn, leading to poor sealing, and it may also cause the coke to overheat. The greater the time the furnace door remains open, the greater the losses – the temperature at the furnace tip drops sharply and leakage increases. It is required that the furnace door remain open for no more than 10 minutes in the case of rammed coke ovens. Everyone, take a look – is this existence a problem for you?
