      Water-tube boiler - Wikipedia

      A high pressure watertube boiler (also spelled water-tube and water tube) is a type of boiler in which water circulates in tubes heated externally by the fire. Fuel is burned inside the furnace, creating hot gas which boils water in the steam-generating tubes.In smaller boilers, additional generating tubes are separate in the furnace, while larger utility boilers rely on the water-filled …

      History of the steam engine - Wikipedia

      The first recorded rudimentary steam engine was the aeolipile described by Heron of Alexandria in 1st-century Roman Egypt. Several steam-powered devices were later experimented with or proposed, such as Taqi al-Din's steam jack, a steam turbine in 16th-century Ottoman Egypt, and Thomas Savery's steam pump in 17th-century England. In 1712, Thomas Newcomen's …

      Mains Pressure Hot Water Systems explained and compared!

      In an unvented system, a vessel is filled with cold water directly from the incoming water main. The vessel is kept under pressure from the incoming water supply and heated either by immersion heaters (a direct model) or by a heat source located outside the vessel such as a boiler or a wet solar system (an indirect model).

      Hot Water Heat Air Bleed Vent Installation & location

      The air scoop is installed at a high point above the boiler and it literally separates or scoops bubbles of air out of the hot water as it leaves the boiler. The air eliminator uses an internal float that will automatically release that air as it accumulates inside the vent.
