Anything greater than or equal to 212F (100C). Superheated steam used in steam locomotives, steam turbines in power plants, etc. can be any temperature from 500F to 2000F depending on the design of the system.
Note: if you can see the "steam" it is not steam. What you see are tiny droplets of liquid water that have condensed from the steam and is probably exactly at 212F (100C) because it is in thermal equilibrium with the invisible steam at the same temperature.
As you'll know, the amount of energy you can get from (say) steam, is limited by the difference between the hottest the steam is, and the condensation temperature. So if we confine the steam, we can heat it well above the usual boiling point, and thus the quantity of energy we can extract is greater.
Asia is huge. There is no overall usual temperature.
No, salt does not affect the temperature of steam. Adding salt to water increases the boiling point of the water, but once the water has turned into steam, the temperature of the steam remains the same.
In order for a high temperature boiler or steam engine to produce superheated water, or steam?
Depends on the temperature of the thing you want to cool down. If it's warmer than the steam, then steam will cool it to the temperature of the steam. If it's already cooler than the steam, then steam can't cool it.
The temperature of 110 psi steam is approximately 338 degrees Fahrenheit.
The steam temperature at 10 PSI is approximately 239 degrees Fahrenheit.
DRY steam is superheated There is a temperature below which steam will start to condense into water droplets. This is called the saturation temperature, and it varies with the pressure of the steam. Steam that is exactly at its saturation temperature is called saturated steam. Steam that is below its saturation temperature contains droplets of moisture and is called wet steam. Steam that is above its saturation temperature is called superheated steam.
The temperature of 50 psi steam is approximately 298°F (148°C).
A condensates return temperature indicates excessive steam.
Of steam seal on a steam turbine temperature in incorrect could cause damage. This could cause it not to work right.
Saturation temperature of steam is the Temperature at whihc any addition of heat does not increase the temperature of the water but produces steam.It depends upon the pressue and for every pressure there is a saturation temperature.
