2019-9-27 · The steam-electric power station is a power station in which the electric generator is steam driven. Water is heated, turns into steam and spins a steam turbine which drives an electrical generator. After it passes through the turbine, the steam is condensed in a condenser. The greatest variation in the design of steam-electric power plants is

Steam Engineering Basics - John Forester

2016-3-22 · Steam Engineering Basics 3 When considering the volume of a pound of steam, consider that a pound of water has a vol-ume of only 0.016 cubic feet. Therefore, even at 200 psia, when water turns into steam, its volume increases by about 14 times. You can see that if you can use the cold sea-water as the lowest temperature, say 60 °F, the

Gas central heating boilers and furnaces - How do

What are condensing boilers? Gas boilers work by combustion: they burn carbon-based fuel with oxygen to produce carbon dioxide and steam—exhaust gases that escape through a kind of chimney on the top or side called a flue. The trouble with this design is that lots of heat can escape with the exhaust gases.
