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

Steam and Condensate - A basic overview of a steam system

The boiler is the heart of the steam system. The typical modern packaged boiler is powered by a burner which sends heat into the boiler tubes. The hot gases from the burner pass backwards and forwards up to 3 times through a series of tubes to gain the maximum transfer of heat through the tube surfaces to the surrounding boiler water.

Residential Steam Boiler Basics - The Spruce

The steam boiler is an old convection heating technology dating back over 200 years and is most commonly found in old homes. Because steam boilers operate at a higher temperature than hot-water boilers, they are inherently less efficient than their hot-water cousins and are more finicky to operate.


The boiler is the part of the system that heats the water to be distributed. The key elements of a boiler include the burner, combustion chamber, heat exchanger, exhaust stack, and controls. Boiler accessories including the flue gas economizer are also commonly used as an effective method to recover heat from a boiler.
