The gas cooling and heat recovery are best taken care of in a loop boiler and the design of this boiler must address the special challenges effectively. The loop boiler is both used to initiate the final cooling of the ammonia-rich gas or as interstage cooling between two converters, for instance, an S-200/300 followed by an S-50 converter.

Cooling of the process gas is carried out in the waste heat boiler, E 3206, where the exchange heat is used for production of the high pressure steam necessary in the ammonia plant. The boiler is designed to obtain a rapid cooling but a too high heat flux is to be avoided, as it may cause film boiling on the steam side, which in turn would decrease the heat transfer coefficient.
