Abstract: A fired heater has two cells segregated by an insulative wall. A first plurality of burners are located in the first cell and a second plurality of burners are located in the second cell. A radiant tube extends from the first cell to the second cell for carrying a fluid material through the heater to heat the fluid material. The flow of fuel to the burners in either the first cell or the second cell can be terminated to accommodate lower heater duty when demand is lower.

Abstract: 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.
