operational systems of fire tube boiler

Common Boiler Problems, Part 1: Low Water Conditions

The only thing that allows a boiler to withstand these furnace temperatures is the presence of water in or around (depending on whether the boiler is a fire tube or a water tube design) the pressure parts at all times that a fire is present. Low water conditions will literally melt the steel pressure parts.

Fire-tube boiler - Wikipedia

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 four major historical types of boilers: low
