A fuel burning apparatus in which water is boiled to produce steam for space heating, power generation, or industrial processes. (more precisely) An apparatus in which a heat source other than a hot liquid or steam (most commonly burning fuel, exhaust gas from an internal combustion engine or gas turbine, waste heat from a process, solar energy or electricity) is used to boil water (or rarely another liquid), under pressure to provide steam (or other gas) for use as a heat source in calorifiers, heat exchangers or heat emitters, or for use directly for humidification, in an industrial process, or to power steam turbines
An apparatus that generates heat (usually by burning fuel) and uses it to heat circulating water (or sometimes another liquid) in a closed system that is then used for space heating, swimming pool heating, or domestic hot water or industrial processes
A boiler is not a water heater When you see the word "boiler" or the phrase "hot water boiler system" in this website or in our publications, this refers to a gas-fired space heating system that distributes hot water through pipes to radiators or baseboards
1 A type of space heating system that heats water or produces steam The heated water or steam is circulated throughout a home or building using pipes and radiators 2 Equipment or vessel that heats water or produces steam for any purpose
Two types of marine boilers existed In the older Scottish boiler, water surrounds an internal fire-box and flame-tubes (similar to the arrangement on a steam locomotive) The flame-tubes, through which the fire's hot gasses escape, much increase the area for heat exchange Conversely, the more modern water-tube boiler heats its water inside many tubes that are surrounded by the fire's burning gasses Water-tubes' heat exchange area is larger than that of flame-tubes and the newer boiler contains less water
A heating device which heats hot water or creates steam for circulation in heating pipes, radiators, baseboards or convectors
A pressurized system in which water is vaporized to steam by heat transfer from fuel combustion Steam thus generated may be used directly as a heating medium or converted to mechanical energy
This is the heart of the engine It contains the firebox where the fuel is burnt to produce hot gases These gases pass through tubes which run the length of the barrel of the boiler and are surrounded by water which is thus heated to produce the steam that is used to propel the engine
Device used for producing hot water for either space heating or domestic hot water
