Boiler - an overview | ScienceDirect Topics

Boiler. Boilers use the heat released during combustion to heat water or produce steam for heat supply or for driving a steam turbine, gas turbines or gas engines use gaseous energy carriers for generation of electricity and mechanical power, and internal combustion engines are used in vehicles (Sims, 2002).

Boiler - Wikipedia

Fire-tube boiler Here, water partially fills a boiler barrel with a small volume left above to accommodate the steam (steam space).This is the type of boiler used in nearly all steam locomotives.The heat source is inside a furnace or firebox that has to be kept permanently surrounded by the water in order to maintain the temperature of the heating surface below the boiling point.

Shell Boilers | Spirax Sarco

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 …
