A steam boiler evaporates liquid water to form steam, or gaseous water, and requires frequent replenishment of boiler feedwater for the continuous production of steam required by most boiler applications. Water is a capable solvent, and will dissolve small amounts of solids from piping and containers including the boiler.
a form of mild superheater that adds additional heat to wet- or saturated steam, thus ensuring that all water in the steam has been evaporated, thus avoiding problems with water droplets in the cylinders or turbine. Unlike the superheater, the steam drier does not attempt to raise the temperature of the steam significantly beyond the boiling point.
The two-pipe reverse return configuration which is sometimes called 'the three-pipe system' is different from the two-pipe system in the way that water returns to the boiler. In a two-pipe system, once the water has left the first radiator, it returns to the boiler to be reheated, and so with the second and third etc. With the two-pipe reverse ...
The heated water/steam mixture then rises into the steam drum. Here, saturated steam is drawn off the top of the drum. In some [which?] services, the steam passes through tubes in the hot gas path, (a superheater) to become superheated. Superheated steam is a dry gas and therefore is typically used to drive turbines, since water droplets can ...
Diagram showing components and mechanism for a heat pipe containing a wick Heat pipes keep ground frozen and inhibit water transfer into the open pit during mining activities at Ekati Diamond Mine This 100 mm by 100 mm by 10 mm high thin flat heat pipe (heat spreader) animation was created using high resolution CFD analysis and shows temperature contoured flow trajectories, predicted using a ...
In other steam-using industrial machinery, water can accumulate in piping and cause steam hammer: a form of water hammer caused by water build up 'plugging' a pipe then being accelerated by the steam flowing through the pipe until it reaches a sharp bend and results in catastrophic failure of the pipe. Steam drier is also sometimes applied to a ...
…at a velocity of 15 miles an hour [24 km/h] the water is lifted 7 + 1 ⁄ 2 ft. [2.3 m], this was exactly the result attained in practice by the apparatus; at this speed the water was raised to the top of the delivery pipe (7 + 1 ⁄ 2 ft. [2.3 m]), and was there maintained without running over into the tender whilst the scoop was in action ...
Pipe insulation cannot prevent the freezing of standing water in pipework, but it can increase the time required for freezing to occur—thereby reducing the risk of the water in the pipes freezing. For this reason, it is recommended to insulate pipework at risk of freezing, and local water-supply regulations may require pipe insulation be ...
