Fire Tube - an overview ScienceDirect Topics

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. It is difficult to solve for the heat transfer in terms of an overall heat transfer coefficient. Rather, what is done is to size the fire tube by using a heat flux rate.

Heat transfer enhancement in fire tube boiler using

2017-2-10 · improving the heat transfer coefficient in tubes of fire tube boiler. The increase of heat transfer coefficient is occurred by change the internal geometry of the tube by helically ribbed shape. This helically ribbed shape generates a centrifugal force on the fluid and forces the flow to be turbulence. A plain tube has a problem which is the
