Boiler wall thickness question - RC Groups

2010-2-9 · Here are some wall thickness I measured with calipers or with steel rule. For the larger locos, at the backhead the boiler shell is exposed and can be observed and measured with a steel rule. For the smaller locos, the boiler shell extends forward, making the smokebox, and the thickness can be measured well with calipers.

Fire-tube boiler - Wikipedia

2019-10-27 · 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

Shell Boilers - beta.spiraxsarco.com

Shell boilers may be defined as those boilers in which the heat transfer surfaces are all contained within a steel shell. Shell boilers may also be referred to as 'fire tube' or 'smoke tube' boilers because the products of combustion pass through the boiler tubes, which in turn transfer heat to the surrounding boiler …
