Abstract
A heat exchanger is presented that provides for mixing of a process fluid to prevent localized spikes in temperatures. The heat exchanger includes a mixing chamber within the exchanger, where a first process fluid passes from process tubes after being partially heated. The heat exchanger further includes an intermediate shell for passing a second process fluid into the fired heater and for exchanging heat with the first process fluid. The fluid flows from the mixing chamber to other process tubes for further heating.
