An advanced coke temperature control system was developed.
Final coke temperature measured when coke cake is pushed out is controlled in order to stabilize coke quality.
It has two main control functions. (1) The target flue temperature is determined by using the heat transfer model of the coke chamber in order to attain the target final coke temperature under the charged blended coal properties and the planned coking time. (2) The input heat is manipulated by the optimal regulator based on the autoregressive model in order to attain the target flue temperature.
This system was applied to a coke oven. As a result, the fluctuation of the coke temperature was decreased and the coke oven heat consumption was remarkably decreased.
