Q & A > Question Details
We have been observing bowings in Radiation coils of a Naphtha Cracker Furnace for ethylene production. What technological improvements in furnace design and coil orientation and coil support system might be available to minimise the bowings? What process and inspection monitoring is needed to minimise bowings in operation? What are the effect of side burners? Generally the Cracker furnaces are not provided with explosion doors? In such case how can box overpressurisation be prevented? Please share best practices in interlocks in Cracker furnace operation.

This is a highly confidential issue. To fix the radiant coil bowing calculations will be needed. For side burner effects radiant box needs to be checked. I may be able to help if you can provide more details. ......
