Coke oven operating limits

Objective

The objective of this research project is to define the safe limits of coke oven battery operating conditions compatible with a long service life in terms of thermal and mechanical stresses.

For this purpose a 3D thermo-mechanical model of the heating walls taking into account the assembly of bricks and joints will be developed. Different sources of stresses on the oven walls will be investigated: thermal load, coking pressure, pushing force.

Theoretical (model) and experimental investigations will be carried out at laboratory scale, in pilot oven and in coke plants to evaluate swelling pressure and pushing force for different carbonisation parameters.

As a result, the maximum acceptable production rate in safe conditions for the battery service life will be defined.
