If our water is in a closed or "water-solid" system, a change in water temperature has a corresponding change in water pressure in the system. These include a steam turbine to produce mechanical shaft power, a condenser which uses external cooling water to condense the steam to liquid water, a feedwater pump to pump the liquid to a high pressure, and a boiler which is externally heated to boil the water to . How do you convert water to steam? The generation of steam takes place in a boiler/steam generator. 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 due to the different fuel sources. With gas (air, nitrogen, co2, or argon) these can be considered non-condensable above 70F. The 1st Law for a throttling device that is adiabatic and causes negligible changes in kinetic and potential energies is : Because the pressure drops in the throttling device and the feed is a superheated vapor, the effluent must also be a superheated vapor. Now, as steam mixes with the air, it loses heat to the air, so you end up with warm air mixed with droplets of hot water. PV = nRT is the relationship among pressure, volume, temperature, and number of moles of an idea. SAME. Notice in the curves on this chart (click to enlarge) of water density (or water pressure) that as our little quotes above illustrated, the density of water increases (pressure decreases) as water temperature increases from 0 to around 4 C, then above that temperature the density of water decreases (water pressure increases) as the water temperature rises. What can be done to reduce steam pressure? Expansion of Steam. Water with a density of 1000 kg/m3 at 3.98 C has a mass of 1000kg and a volume of 1 m3.
