WebMar 12, 2012 · A 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 … WebSep 14, 2024 · In most cases, convection has been identified as the way that fire is spread in workplaces, and is also common in homes. Materials of a combustible nature can easily catch fire and cause an even faster and more damaging spread of fire, which can be difficult to contain and lead to major damage and even injury.
