Abstract
Aspects of the invention provide a heat exchanger that includes a shell coupled to a top tube sheet and a bottom tube sheet. The shell at least partially defines an interior region. The heat exchanger also includes a burner positioned to deliver combustion gases into the interior region. A plurality of tubes, configured to circulate a fluid therein, extend through the interior region around the burner. The heat exchanger further includes a divider that extends within the interior region from the top tube sheet to the bottom tube sheet and between one of the plurality of tubes and another non-adjacent tube of the plurality of tubes. The divider and the plurality of tubes define a receiving section of the interior region for receiving combustion gases from the burner and an exhaust section of the interior region in fluid communication with a combustion gas vent.
