Processes and apparatuses for relocating a reforming process heater service into the convection section rely on combining a flue gas recycle quench stream with the radiant section off gases entering the convection section. The uniformity of mixing influences the effectiveness of that quench stream. The more effective the quench stream is, the lower the equipment size required to manage the recycle design.

A thermal process device for heat treating a product or plurality of products includes a thermal processing chamber having opposed distal ends and a plurality of controllable heating zones. At least one buffer zone is disposed at each of the distal ends. The buffer zones and heating zones of the thermal processing chamber form a heating element assembly.
