Kettle Type Heat Exchanger or Kettle Reboiler 3D model

A kettle reboiler consists of a horizontally mounted TEMA K-shell and a tube bundle comprised of either U-tubes or straight tubes (regular or finned) with a pull-through (type T) floating head. The tube bundle is unbaffled, so support plates are provided for tube support. Liquid is fed by gravity from the column sump and enters at the bottom of the shell through one or more nozzles. The liquid flows upward across the tube bundle, where boiling takes place on the exterior surface of the tubes. Vapor and liquid are separated in the space above the bundle, and the vapor flows overhead to the column, while the liquid flows over a weir and is drawn off as the bottom product.
