If you heat steam under pressure you get "superheated steam" under higher than original pressure

steam is lost in the plant through variuos way. But generally it is through heat transfer to the product to be heated by the steam. Also heat transfer through the conducting passage.
The heat transfer coefficient of superheated steam is poor. Saturated steam has a better heat transfer coefficient, and also most of the heat transferred from steam occurs because of the condensation phase change.
when steam is at its saturation point for a given pressure, any heat removed will cause liquid water to form. So when saturated steam is used to heat something else, the heated object/substance receives the condensation heat of the steam. The latent heat of condensation/evaporation is 970 But/lb @ 0 psig. On the other, superheated steam only gives up about 10 BTU/lb if it is cooled 20 degrees F. That means that much more steam would be used to transfer the equivalent amount of heat. The liquid water interface also improves the heat transfer.
Dry steam systems are a heating and coolingÊsystem that has steam that does not contain water droplets. Radiant systems are where heat and cooling systems where heat is exchanged through convection and conduction.Ê
The nuclear reaction produces heat The heat is used to make steam The steam makes the turbines spin The turbines make electricity
A steam engine uses water, steam, and heat.
The total heat of steam, also known as enthalpy of steam, is the amount of heat required to raise the temperature of water to its boiling point and then convert it into steam without changing its temperature. It is the sum of sensible heat and latent heat of vaporization.

A steam burn is an example of latent heat, because beside the heat released by the steam itself, a part of it condenses, turning into water, which in turn releases heat too.
Ordinary pressure steam scalds the skin and tissue, and whilst condensing causes further heat insult. Superheated steam acts like a thermal lance and cuts into the tissue as well as scalding and burning deep tissue.
Nothing, a steam boat runs not on steam, but on a heat source GENERATING steam. this heat source is usually coal but could be wood or a fossil fuel.
steam (heat creates steam)
Steam is generated by heat from the combution of fuel in a furnace or by waste heat from a process. The heat is transferred to water in the boiler shell, which then evaporates to produce steam under pressure.

Heat it.... The heat will first convert ice into water and will then convert it into steam. You can heat ice in any kettle.....or saucepan.......
