Abstract (en)
[origin: EP0499897A1] In a process for controlling the transition temperature between the convection zone and radiant zone in cracking furnaces for olefin production from different hydrocarbon feedstocks, the feed stream is divided into two part streams before introduction into the convection zone, the first part stream is first preheated and then mixed with process steam, subsequently mixed with the second part stream untreated up to this point in time, and the resulting total process stream is passed after further heating and/or vaporisation into the radiant zone. The mixing of the first part stream with the process steam can take place before or after internal or external super-heating of the process steam. <IMAGE>
