Combustion management within a steam cracking furnace

摘要

In a steam cracking furnace, a combustion is carried out to supply heat to the endothermal cracking reaction via indirect heat transfer to cracking coils inside a radiation chamber. In this context, combustion can be referred to as a high-temperature exothermic reaction between a fuel and an oxidant, that produces oxidized flue gas products. Different fuels can be applied, having an impact on certain combustion properties, in terms of e.g. adiabatic flame temperature and/or certain radiation properties, among others. Such fuels or mixtures thereof are mentioned in the following, starting with the "most efficient" fuels, e.g.:1.H2 2.CH4 3.NH3.
