what is a boiler

A boiler is a closed vessel in which fluid (generally water) is heated. The fluid does not necessarily boil. The heated or vaporized fluid exits the boiler for use in various processes or heating applications,[1][2] including water heating, central heating, boiler-based power generation, cooking, and sanitation.

“Boiler is a closed vessel in which water or other liquid is heated, steam or vapor is generated, steam is super-heated, or any combination thereof, under pressure or vacuum, for use external to itself, by the direct application of energy from the combustion of fuels, from electricity or nuclear energy.

A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a steam generator.

What is a Boiler? The name is a bit misleading, because a boiler doesn’t actually boil water. Instead, a boiler turns water into steam. Boilers can be used to not only heat water, but also heat your home and even generate power. Boilers heat water very quickly, and like hot water heaters, are available in tanked and tankless versions.

A boiler is an enclosed vessel that provides a means for combustion and transfers heat to water until it becomes hot water or steam. The hot water or steam under pressure is then usable for transferring the heat to a process.

Boiler definition, a closed vessel or arrangement of vessels and tubes, together with a furnace or other heat source, in which steam or other vapor is generated from water to drive turbines or engines, supply heat, process certain materials, etc. See more.

A water-tube boiler is more thermally efficient than a fire-tube boiler, but they are more complex to construct and the quality of the water can be a limiting factor. The water may need filtering to operate most effectively.

A boiler economizer is a device that is designed to increase the operating efficiency of a boiler, cutting down on its operational costs over the lifetime of the boiler. Although the savings on any given day may be relatively small, the impact over time can be significant, especially with a large ...
