Beschreibung
Zusammenfassung:	A method is described for controlling a furnace containing a plurality of catalyst-containing tubes heated by a combustion gas generated by a plurality of burners, said method comprising the steps of: (i) measuring path-averaged combustion gas temperatures on multiple paths through the furnace using tunable diode laser absorption spectroscopy, (ii) periodically measuring temperatures of surfaces within the furnace to obtain periodic surface temperature information, (iii) entering the path-averaged combustion gas temperatures and periodic surface temperature information into a computer model of the furnace, said model comprising parameters for controlling the furnace; and (iv) using the computer model and the temperature information to obtain optimised parameters for controlling the furnace. A system for performing the method is also described.
