vibration in fire tube boilers


Water Tube Boilers - Trainorders.com Discussion

Couple guys mentioned "fire tube boilers" and "water tube boilers" as if they were opposites. But steam locomotives that use water tubes always? have fire tubes as well. The water tubes surround the fire, but the combustion gases (etc) go horizontally forward through the firetubes-surrounded-by-water, same as a regular locomotive.

Fire-tube boiler - Wikipedia

A fire-tube boiler is a type of boiler in which hot gases pass from a fire through one or 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 four major historical types of boilers: low-pressure tank or "haystack" boilers, flued
