Fire Tube - an overview ScienceDirect Topics

Mar 12, 2012A fire tube contains a flame burning inside a piece of pipe, which is in turn surrounded by the process fluid. Radiant and convective heat transfer occurs from the flame to the inside surface of the fire tube. Conductive heat transfer occurs through the wall thickness of the tube and convective heat transfer from the outside surface of that tube to the fluid being heated.Fire Tube - an overview ScienceDirect TopicsMar 12, 2012A fire tube contains a flame burning inside a piece of pipe, which is in turn surrounded by the process fluid.
