Fire-tube boiler - Wikipedia

2019-8-10 · A fire-tube boiler is a type of boiler in which hot gases pass from a fire through one or (many) more tubes running through a sealed container of water. The heat of the gases is transferred through the walls of the tubes by thermal conduction, heating the water and ultimately creating steam. The fire-tube boiler developed as the third of the

how to size a kettle reboiler - Chemical plant design

2006-12-8 · If you are going to use a direct-fired reboiler (I assume you'll burn natural gas) then it would depend if you're doing this for a client, for your own company, or for yourself. When "sizing" the fire tube - which is all you are really going to have to do - use only an empirical heat flux value as your sizing tool.

Steam Generator versus Steam Boiler - ttboilers.com

2018-11-5 · The principle in the fire-tube steam boilers, is that from the surface of a large volume of feed water, steam is evaporated. This boiling process is heated by the wall of the combustion chamber (the radiant part) and by the exhaust gasses passing through a bundle of so-called fire-tubes or smoke-tubes forming the the convection part of the boiler.
